That's the thing - the DV recirculates after the MAF, so all air is accounted for even if the DV is leaking.

 

but the air that the MAF things is going to your IM is being leaked out of the DV and getting put back in before the turbo to be recycled. it never really made it.

 

Indeed, but the turbo is reusing the air that got by the DV, so less air is going through the MAF at that moment.

 

I don't think it reduces the a amount of flow through the MAF, though.

 

Fixed any possible fuel issues. Upgrading to FIC 1050 injectors Kevin has on hand, so I should be able to make pretty good power I assume? On MAP's website they had an EVO 8 with similar mods, but with O2 dump and cams and made 446hp on their mustang dyno, so I figure with a megan O2 housing on a IX motor with all other mods the same, I should be able to do 400-420 on a mustang, or 450-460ish on a dynojet. Or is that being too optimistic?

 

You will need aggressive cams, ditch the cat, and e85. That should get you 450 on a Dynojet pretty easily. I have a mild cam and am expecting 430-440 while still being able to beat on it reliably.

 

That seems a bit much for 450whp dynojet on 93. I guess we'll just have to wait and see. E85 isn't an option, cams aren't worth it, and neither is ditching the cat. A test pipe over this cat would yield me another 3whp, and I was told that at my mod level cams wouldn't do that that much more anyway. Not worth the price for another 10whp. E85 would make more power, but it's too big of a hassle, and I don't know where to find it out here.

 

sounds like you have it figured out then . my mild cams gave me a 30ish whp bump but that's on a mostly-stock setup. i've never used 93 oct, but you are shooting for 60whp more than i'm making on 91, but using a less aggressive setup. if you made 450whp on that setup, i'd be seriously impressed. that would be amazing. good luck, man and post the results! i may let my tuner talk me into that extra 2psi he was asking for LOL

 

Are you sure you are talking dynojet numbers though? I know I can't hit 450whp on a mustang, but my tuner said I should make around 410-420whp on their mustang, which would put me at around 460-470whp dynojet.

 

I don't think you guys are talking apples to apples.

aka, you are not talking the same dynos.

I don't even remember what turbo you are talking about, but most of the EF turbos can hit 450whp on a dynojet easy.

 

yes, sir.

ef2.5 with a few bolts-ons, a HFC, and 93oct.

 

Yeah, I agree. MAP made 446whp on Mustang dyno with an EF2.5 on an EVO 8 with a couple mods that I don't have. If they did that on a mustang dyno with an 8, I figure I should be able to get 450whp on a dynojet with a IX. I could be wrong, but I guess we'll just have to wait and see. This heat definitely won't help matters.

I'd call that more than "just a few bolt ons" lol the only thing I don't have is cams, and at the current mod level and tune before the rebuild, I was told cams wouldn't make a very big difference, especially for the price, so I got the ported manifold instead.

 

Not sure why you were told cams won't make a big difference?? I make 450/350 (Evo 8) dynojet with an ef3 toxic fab manifild, o2 dump, and s2s with other supporting mods of course on 92 octane. I think you may fall a tad short of your goal of 450 without cams but I could be very wrong. I'm just giving my .02..

Also cams are more then just 10hp up top they broaden the entire power band just with s2s my buddy's IX picked up 40ish in the middle of the power band and another 15 up top with a much smoother power band. Ppl forget its not always peak HP gains you have to look at how it can improve the power band as a whole

 

I agree with you, but for the price they wouldn't make a huge enough difference like they would on an 8. If I do decide to go the cam route, I'll look into the GSC S1 cams. Their range is 3000-8000rpm which is what I want. I like good low and midrange power. We'll see what the car does in a couple days. I can't see it making less than 450hp dynojet though on a built motor with supporting mods. With the stock motor, stock turbo, stock intercooler, stock upper IC pipe, stock turbo manifold, 5psi less boost, and smaller injectors I was making aound 380-385whp on VD. I can't see adding those mods, and that boost and only making another 20hp. Like I said, I guess we will see.

 

By no means am i saying it can't be done.. i'm not sure if you noticed my post last page but i'm currently sitting at 420/415 on a dynojet with a 2.4/EF4 with GSC R2 cams.. granite it i'm running super rich and was in a 100 degree weather on 91 pump but im also pushing 30lbs of boost as well... so making 450 on pump is no easy task
