horse power

[explorer_john]

i was wondering if anyone knew how much horse power mine has. it is a 4.0 v6 and how i can increase it.

 

[5.0 explorer]

not sure on how many horses, in the ball park of 150ish at the crank??
but with a nice cat back exhaust system and a intake system would be a good start in increasing HP's !!

More like 210 Crank H.P oem

 

[Joey P]

Yeah, if it's the sohc, then 210 hp. Don't know when they stopped making the ohv, but that was 160 hp.

Depends on what 4.0 you have. The SOHC or the OHV.

 

[explorer_john]

mine is a sohc thanks anyomre suggestions on how to increase it

 

[5.0 explorer]

I believe they stopped making the OHV in 97
I could be wrong tho..

Open intake, 2.5 inch catback exhaust, all syn oils, 91 octane gas, apten chip will get you approx 20-25 more crank H.P

 

[explorer_john]

cool what exhaust exactly would be good

 

[5.0 explorer]

the Magna flow system is nice
I like the Gibson single side duel outlet system

I think the Flowmaster system sounds like crap in the 4.0L

 

[explorer_john]

thanks

 

[spindlecone]

I think from a HP gain standpoint all aftermarket exhaust are about the same, I have a magnaflow, works for me

 

[explorer_john]

does it change if it a dual out or not

 

[spindlecone]

IMO. one will gain more HP from a single catback than a dual catback

 

[aldive]

IMO. one will gain more HP from a single catback than a dual catback

Agreed.

I don't know about that one, I have the OHV in my 2000 XLS.
