Hey I wonder if anyone can fill me in about how much whp I should expect. I've got a IX. My mods are Injen Intake, Injen upper and lower intercooler piping, ETS 3.5' widebody fmic, Cobb 3" TBE, Turbosmart MBC, Walbro 255, HKS 272 in/ex cams, and I'm going to get a custom tune by Cobb Tuning this Tuesday. I was thinking this set up should make some pretty sweet power, but I called Cobb and they told me to expect only about 300 whp. I was bummed because I expected way more. My friend has a IX with only exhaust, headers, hard intercooler piping and AMS EBC, plus a custom tune, and he was putting down 320 at the wheels! How is it that I've got everything he has (minus the headers) PLUS the ETS intercooler and cams and Cobb says I would only be around 300!? Tell me it's not true! Thanks for any info.

 

it depends on dyno but I'd say 340+

 

i made 330 with tbe intake cams and ebc and walbro 255.

 

i did 370whp on 24PSI with my full bolt ons and same cams as u. with 4WS. You should try him out.

 

wow. that sounds more like it. So ithis is probably a stupid question, but who's 4WS?

 

http://4wstuning.com/ go on his website. His name is Tamer, he is located in Florida. A good friend of mine. I only deal with him when it comes to tuning. He is very knowledgeable and provides Fantastic customer service !

 

cool. thanks.

 

Between 370 to 390 with a aggressive tune to the edge,make sure you have some head stud's and the fuel pump for added safty,my evo made 362whp with just a stage 1 buschur kit not bad for 1,200 buck's

 

he probably meant 300 on a mustang dyno. 300 on that kind of dyno will yield much higher numbers on a dynojet.

 

Tuned correctly, 355+ whp on a Mustang Dyno (if your motor is in tip-top shape) could be achieved. A customer here with Kelford 272s, Megan 3in tbe, Injen kit, Forge UNOS mbc, and a Walbro 255 fuel pump was tuned to 370+whp.

 

It is a mustang dyno. I guess they're pretty conservative.

 

DAMNIT I HATE THESE THREADS!

go take it to a dyno and find out!

 

 

i would say around 370whp also... i made 340whp with the same bolt ons and cams but i have an 8... damn mivec lol

 

Ready for this BS. Just got back from Cobb, and I made (wait for it) 269 whp! WTF!? It's a mustang, so they said it could be as much as 315 or so on another dyno but damn! That just sucks! 269! So I asked what the problem is and the tuner said that my car's not holding boost. He tuned it to 22 psi but it tapers down to 17 psi after 4500 rpm. They don't know why it won't hold boost Cobb says that the dyno printout looks like the power would continue to about 315 whp if the boost didn't drop. They said it could be a problem with the MBC (but it's brand new, so that's probably not it), plus the shop that installed the cams said they tested for boost leaks and didn't find any. So what the hell is wrong with my car? I just dropped $1600 for the cams, install and tune and I got 269 whp? Anyone know why I might be losing boost? Any help would be greatly appreciated.
