Exhaust performance gains??

Just my opinion but I would put the Cobra emblems on there before I would put the SVT emblems on there just because the Cobra doesnt stand for any acronym per-se where as the SVT lettering does. For me to feel justified in putting a Corba or any other emblem on my truck I would have to had raced a person for them first. I already have this in plan for a race with an 03-04 Cobra. I will offer the guy $150 to race and if I win I get his Cobra emblems. If he wins he gets my money. Even then I would never label my truck as an SVT in my sig or call it that. If anyone asked me what the emblems are doing on my truck I would tell them why. That would at least earn me respect and validate things to a certain extent as to why my truck was wearing those things. Maybe I overthink this, but that is the way I feel on it.

Yeah maybe your right bro... like I said... when I originally ordered the emblems I thought it just stood for Supercharged Vehicle something... if from the get go I would have know it was a department company from Ford I would have just slapped on the SC emblems... but I have what I have.. maybe ill hunt down a local SVT car ive seen around town and race him for his emblems... and earn those badges

Hell yeah! Thats what I'm talking about!


So have you had a chance to go to the dragstrip yet? Any dyno sheets you got that you can post up so we can see what kind of power your making?

Man I wish I did... I dont think you know of the last dramma I went through... I ran my motor for 280 miles and spun a frickin rod bearing... :fire: just as I was doing my last tune with my LM1 and Xcal2... got that A/F down to a T though at WOT... then all of a sudden ... ding ding ding ding... tor my motor apart only to find out that the dong head that put her together checked no tolerances... ALL my bearings were scuffed. Real bummer... so I said screw this... im sending my motor to a pro... soooo John at Modular Performance has my long block now I should have my new motor in about 3 weeks.... its getting the absolute works... no mercy anywhere...

From then ill tackle my drive train in a few months (if i dont blow it first at least). Im really excited on that part of the project... I found a bullet proof TC, its an ATLAS II... they use them in the baja trucks... the guy was teling me that those trucks are screaming at about 100mph and when they come to a sand hill or something they just slam that TC to 4WD and never look back... those trucks have to be pushing like 600rwhp easy... and man do they abuse... Its not expensive either... it will be manual with two levers... the beuty is that i can now go 2wd or 4wd as I please.... 2wd and 4wd high are at 1:1

So concidering I will be able to go into 2wd I can then take the EDIT: 1,500 mile drive to Mexico City and jump on their 2wd dyno

Then when I finally get the whipple 2300 ill drive back for another dyno run.

But ill keep you posted when I get my new motor.... they say third time is a charm right!!! I just want a realiable motor... I really miss driving her... its been like 6 months since ive really enjoyed her.

 

[rocket 5979]

That sucks about the problems. That is the main reason why I am going with VT engine and none other. Even if they do somehow mess it up, I know it will be covered.


It is funny to see someone crying about not seeing their vehicle for 6 months. I havent seen mine in two years! lol. I would say that by late this next Spring I should be ready to race for emblems against a modded Cobra. I will be putting my order into KB for the 2.2 in a little over one month and might just put my order into VT then also because they have such a huge backlog of engines to make! I figure order it in a month so it will be ready about two more months after that. After that I will do the tranny, if it will physically fit into the 5R tranny tunnel, when I can later in the winter and finish up by spring with a few other big things. Probably by late next racing season I will get a set of P&P'ed Patriot heads with some nice blower cams in them. After I snap my axles I will order a custom-made set from DSS and spend an arm and a leg doing it! Once stage one is done early winter I want to make around 400 rwhp. After stage 2 later in winter I want 600+. Then after things break and I replace those I will throw a small 55 shot of the juice on there and see if I cannot see 700+, but that is stretching it. I should be happy with 550-600+ for a while. Just glad this is not my daily driver! Whew all I can say is that this money is burning a hole in my pocket! Glad I decided to pay my truck off early, otherwise I would have had well over $35,000 to blow on the truck and that would be plain rediculous! As for now I should have about $15,000 to start things off right away when I get back. Sure is a PITA to save up all this energy for two whole years! I feel like I am going to explode.

 

[awdrocks]

yeah this is a intense project... and one and onlys thats for sure... I hear you on the coin... ive literally thown away sooo much money. I just bought a complete forged bottom end and paid for a lot of labor on the build... and it lasted 280 miles.... I could have already finished my drivetrain... if you or anyone is interested I have forged pistons and rods with only 280 sitting in a box.... .020 overs. My new pistons will be 3.70 bores Yep and with a warrenty.. theres only like 4 companys I would trust in the entire county with these Mod motors...

ive got the drivetrain worked out... with the new TC and TRANNY there is only like a 1/2'' in length difference... which can easily be fixed with the new driveshafts... cobra halfshafts will be fitted one way or the other.. after watching a few episodes of overhaulin and chop cut rebuild you tend to see that anything is possible when you put your "wants" to.

Robert, are you going to use a SOHC KB, or the Cobra DOHC version? Here is a picure of my new KB 2200, bare. I hope to be building brackets over the Winter. Regards,

Man that charger looks like sex! hehe. I will be going with the one for the SOHC. I want the launching torque that the 2 valve will give me versus the 4 valve. This will also save me money and heartache too. Another big reason for me doing this is because until I get my fully built engine I will run the 2.2 on the stock bottom end with a 4" pulley and only make 9 pounds of boost. That will keep it safe until I drop the new engine in there and then turn the wick up to about 20 pounds. I dont plan on having this be a total dragracer yet which means that I dont want a rollcage or anything. But I do want it to be able to go 11's at the track. Once I do my 11 second pass I will just take it easy from there and leave it alone. Then comes the real fun with project #2 which should be a breeze in comparison...

 

[rocket 5979]

Don I must admit that I am kind of jealous of ya. You get to do what I wanted to do over 4 years ago, which is slap a Kenne Bell on a 5.0 explorer. hehe. That is going to be a fun ride when done!

I hope you get your project off the ground. Just a little constructive advise and not trying to start any wars. Ive been refraining from saying this because people seem to get offended easy and take things the wrong way. But now I figure if your really going to do this project someday at least be aware of the right mods to a MOD motor and ide hate to see you throw your money down the drain.

The ONLY way to make real power on a 4.6 mod motor is to increase the bore size. Stroking it is a waste of time... the stroke is already to long on this mod motor. Here are some dyno numbers to prove it and notice VT Engines is in this post. The SOHC BB 305 is only within 20hp of the DOHC STROKER 324!!! a DOHC 5.0 STROKER would be even worse and a SOHC 5.0 STROKER even lower!!! Nothing touches the DOHC BB, not even the STROKED 324 5.3 DOHC with more aggressive cams. The results are obvious and proven with DYNO backups. I was originally going to do the 324... but im staying WAY away from that now. I want reliable and real power.

Now a 5.4 BB/Stroker DOHC is a whole different story.

If you decide to go big bore the best is with Modular Performance or Renagade... if you go stroker I guess stick with VT as MP and Ren wont even build a stroker due to liabilities.... stroker mod motors are torn down to much. VT will also build you a BB.

And Patriot heads are junk.. stay away from those heads. If your serious about the project no one PnP heads better than Renagade.. period.. expensive and only does one stage... full massage... but the best. Look at this:

Thanks Robert for the kind words. I see what you mean about the SOHC engine choice. That sounds good, and well thought out. I do hope that a five or six speed transmission can take 500+ lbs.ft. of torque some day. The gearing would be much better for a daily driver.

I believe about 90% of my project will be mounting the KB, the bracket fabrication, and intercooled upper intake plenum. Somewhere along the way, I will need to select a pulley size. Do you know of someone who could help me choose one to give me 8-10 pounds of boost?

I will prepare everything except the engine. The fuel system will be done, as well as the transmission, brakes etc. I want to break in the PCM and combination with the stock engine. Any mistakes with the tune are more likely in the beginning. I am not going to take the biggest risk with an expensive new engine. Once dyno tuned, then i can ease into a built 331, and be less likely to hurt it.

I need to bookmark this thread. I haven't had time to think about my next project, a 98 MarkVIII. I see a new Cobra engine dropping perfectly into it. Regards,

Do you want to know why he doesnt post much about actual tech talk here anymore? It is because he got fed up with poeple like you that shoot your mouth off like you know everything.

Don,
Do you plan on swapping to a manual or staying auto? I am guessing an auto. That is one of the reasons why I am somewhat jealous of the 5.0 explorers because they still have a good strong tranny behind them that can hold a ton of power with a fews simple mods. I could go into the details about why the 4R is allot stronger than the 5R but I dont want to bore anyone. Lets just say that is has to do with the way they shift. Man if I were doing a 5.0 Explorer project I would give a place like Lentech or Level 10 a call and see what kind of tranny they could hook you up with. Even the stocker if in good shape with an extra aux tranny cooler and shift kit will take a pretty good beating. A good time to swap it out would be when you go the new engine, since I am guessing that once you drop that in that you will be turning the boost up too, right? Speaking of boost, with the 2.2 you will probably need to go with something like a 7" crank pulley to a 4" head unit pulley to get about 9 pounds. On second thought you might want to go with a 3.75"-4.0" pulley as you probably wont plan on revving your truck much past 5,000 rpms if that. By the way the 4" pulley is the biggest that KB offers so unless you purposesly throw a few restrictions in there then you will be making a minimum of 8-9 pounds or so right off the bat. Man that intercooled intake plenum is going to be a PITA but still doable. Are you planning on using anything from the intake of the Kenne Bells that are made for the 5.0 or will all the plenum from the charger head unit on down be custom? I think I have seen one fella do the whole custom thing before and man it looked friggin hard! lol. Well, I guess that is what makes it fun is the reward at the end of a hard job done. When you do start the job take a few pictures and post em up for me to see. I remember when I did my 5.0 supercharger project I tore allot of the front end off my truck because I dont like to work in tight places. It actually looked pretty cool all torn apart and laying open. I wish I would have taken more pictures. I might just have to take a short video here and there of this next one to show the progression. Your going to have a fun truck on your hands bro. Next year should be a pretty interesting year for a few of us.

Thats cool bro... I kind of thought it would go this way. I should have kept my mouth shut. I dont claim to know much... But I do read and all I sent was actuall facts from peoples experiences. Facts.. DYNO and testimonial... Just another insite on mods... and im sure we can all learn a little more once in a while... with the simple fact that you want to purchase PATRIOT heads is kind of a dead give away of how much research you have done... or for all means... what you know as you state it.

I beg not to start a war... I was just giving friendly advise... please dont take things so harsh. Just asking to open up a little.... maybe I do seem to be condesending... not my intesion.

I like these threads are are very imformative. Like you said... you do things your way.... thats great... oh well... at least hopefully i saved you from buying Patriot heads... if thats the case then my post was worth it to me... just given a helping hand.

Good luck and I wish you the best of luck on your projects.... PEACE...

Well at least we got an understanding now. As for the Patriot heads? Well it seems that every company, especially when dealing with us spastc car nuts, are going to not be able to satisfy all the time. I have heard mixed feelings on the Patriot products just like I have heard on pretty much every other mod offered for the 4.6 and 5.0. I originally started with planning on a set of VT heads and their blower cams too, but I knew if I was going to do that then I might as well buy an assembled longblock. I didnt and still dont want to spend that much money in one drop. Either way the heads will be a little ways off, I am not even focusing on them that much at this point. My focus is on the head unit and the tranny for now.

Cool deal bro... im GLAD we got though this. I can soak in a lot before I burst.. You know its not a lot of people tackling this job and it would be a shame to go our seperate ways.... By the way I know who Troll is.... as a matter of fact he is the original reason and my inspiration for this entire project. Troll... if you read this... HATS of to you and your team.

When I first got my SC I was going to stop there... I honestly thought it was a waste of time and money to dump so much into an X.... YEAH right untill I saw those Vids of Troll and some other 2nd gen doing donuts .... I said... ok the project starts NOW.

Nail that drivetrain... once we are there we are golden....

 

[rocket 5979]

Hey Don if ya want the formula to compute for the pulley sizes it goes as such: First find the ratio between the two pullies. We will use a 7" crank and a 4" head unit pulley. That gives a difference ratio of 1.75. Then the formula for the rest is, (supercharger size in liters X pulley size ratio) divided by (Engine size in liters divided by 2) X 14.7 - 14.7 = Boost output.

In your case it would be (2.2 x 1.75) / (5.0 / 2) x 14.7 - 14.7 = 7.9 psi


I dont know what size crank pulley you decide to use but I would suggest going with the smallest one possible and going with the biggest pulley possible on the head unit for whichever given boost you plan on running. What this will do is give more surface area of beltwrap for the head unit so you dont have belt slip in the upper rpm's.

Rob, I am going to use the 4R70W. I have a spare 97, but I may just pull the 98 and build it. I have installed just about every AOD shift kit made. I dealt with the owner of Level 10 before they got big, and expensive. I bought a kit for $210 which included Kolene steels, and blue frictions. To get them again when I called for another AOD, they only had them as part of a $450+ kit. I have not driven in a Baumann kit AOD, but I have installed one in a Mustang. I really liked my AOD with TransGo HD kit, in my 91 Mark VII. That's the trans that got the blue frictions, Kolene steels, and AODE OD band, etc.

I expect to end up in the 14 pound range of boost on a 331. There is an Eagle Trans/torque converter company who has a $565 torque converter that sounds promising. I have a spare complete 97 302 that I will build brackets for, to mount the KB. I hope to have the outlet around where the alternator is now, and cut apart an upper intake to make the plenum. I am leaning to the Victor 5.0, because the upper plenum looks bigger. I will buy whatever intake seems to be closer in dimensions to what I will need for the intercooler.

I will take lots of pictures. Regards,

I believe that there is only one crank balancer/pulley for the Explorer. I haven't measured it, but I'd say it's not over seven inches. Thanks for the formula, those are good facts to have. Is the result based on a decent air inlet temperature? I won't have hot AIT, but possibly lower than average. Regards,
