Shoot at 5500rpms it is WAY off the map. If the OP hears a "weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee" sound coming from his turbo he might want to get off the gas. haha.

was wondering, im wanting to put together my ic piping from light gauge mild steel tubing so that i can weld it together instead of using a ton of boots and clamps. anyone have a good source to get bends and such for that? and what size piping you guys think i should go with? ill need to ramp it to 3" for about 12" or so for the maf (running blowthrough 05+ mustang slot maf) but other than than, 2.5"? 2.25"?
Measure the compressor outlet of the turbo and keep the cold side piping that size, or the next convenient size up, until the FMIC and then step up to whatever size the fitting on the FMIC is. Come out of the FMIC and stay at least the same diameter of the outlet with your pipe. Once you work your way on up to the engine bay then expand out to the 3" pipe and have at least 12"-18" of straight unchanged pipe before MAFS and preferably about 4"-6" post MAFS too if you can swing it.
No, just kidding...I'm not sure how it's going to feel. I mean, it's for sure going to spool up fast. But you can build a turbo set-up using this turbo and later change the turbo (if needed). It won't be that bad. I say full steam ahead!
96 ranger. and why do you say 10:1 compression isn't ideal for a turbo? tons of people boost higher compression motors.. more static compression just means less boost for the same power level.
the sohc motors are stock 9.7:1 compression with tons of people throwing superchargers on them. does the tune need to be really good? yes..
do iat's need to be low? ya, but that's why we have high octane fuel, intercoolers, meth, etc.
my tune will be very conservative, meaning im not going to throw a huge amount of timing in it just to squeeze more out of it, it will be on the safe side for sure.
If it was me and you do rebuild your bottom end and get a bigger turbo i would go to 95+ ohv piston and drop back to 9:1 thats just me.im more of an nos guy though and it loves higher compression
I respectfully disagree. I think that high 9's to low 10's for cr is perfect for a turbocharged street or street/strip vehicle. You still retain off boost power and can still turn the wick up and make good power on boost too. I have built many a turbo systems for vehicles running anywhere from 10.1 cr to as high as 10.75 cr with outstanding results. The key is in how you fuel it and tune it. If you go much lower with cr on a turbo car then the vehicle is just plain nutless off the line. Now if we were talking about positive displacement superchargers who generate great off-idle torque but also generate very high IAT's then I would agree that 10.0 cr would be too high.

You know way more than me,like i said im a nos guy.maybe peole just say that because they dont wanna deal with all the rest or just doing cheap builds.so with good tune is a 10:1+ cr better than lower cr?does it make more power at the same boost?
a higher static compression motor will make more power because the end cr will effectively be higher than a lower compression motor at the same boost level, assuming that the cr is the only difference between the motors.
So can you put more boost into a lower cr motor?if so would the extra boost make more power than a higher CR lower boost motor? Just trying to learn alittle,everyone i know all ways talkes about lower CR and boosting the hell out of it
exactly, the lower compression motors can take more boost because there is more room in the combustion chamber to pack the air into. the lower compression, you make it up the lost power with more boost.
haha.
