I'm installing a gt35r and I want to use the buschur intake which brings the air flow meter . It's that gona restrct my turbo from making power?

 

Are you using stock ecu?? if not why would would you put back in the AFM???

 

Yes I'm on stock ecu . I'm using a 4" coupler reducing to 3" and I want to know if that gona be an issue when I tune because my friend had an issue the turbo was boosting 27 psi on a 35r and the car was making 370 max and the tunner said it was the AfM so he got a maf translator to be able to eliminate the AFM then he made real power 501whp

 

Well looks like you answered your own question.. 27psi on 35r and only 370whp sounds like something was wrong with that car.. Actually something is definitely wrong with that car even thru the MAF it should make 500+..

 

yeah but there some other people who have had no problem making this kind of power and he used the AFM so I'm confused

 

like i said above something was wrong with your friends car if it made only 370 with the maf @ 27 psi on a 35r.. it doesnt add up..

I have seen 520+ on 27psi thru the maf on a near stock 35r car..

 

no AFM is probably best. i haven't gone that route with my agency power gt35r setup yet, but i have utilized their supplied MAF pipe. it's 3" too.

using the stock snorkel absolutely sucks for spoolup and i'm sure it hurts top end (not to mention you have to figure out how to mate it correctly).

a solution could be dejon's gt35r pipe which i want to order soon. it cleanly mates to the 35r and then the only bottlneck then is the MAF's diameter. i don't think your friend gained all of that HP just because of the MAFT. there are a number of evo running high numbers with stock like intake piping.

if you go the MAFT route, either blow-through or MAP, you probably won't have to deal with idle/lift off stall issues and such that i have dealt with (solved with bez's map to maf patch ported to my rom). so--in effect, if you want to do it right, and the tuner can tune it, go the MAFT pro route. everything can be dialed in and you can use your own intake pipe solution.

you will need provisions for a new IAT sensor, map sensor for the SD setup, or you will need provisions for a GM MAF, couplers and UICP piping for the blow-through method.

let us know what you decide. maybe i'll go that route.

 

Well if mike says that with the maf I can make 515whp I'm just gona leave it how I have it because 515 whp is my goal

 

good choice. i'll contradict what i said earlier being that the MAFT is the right way.

the reason i haven't gotten that unit is that i don't like units that skew A/F HZ numbers. it does create a good solution for some people though. i know a good tuner and some time can get it dialed, but simpler is better [for me].

soon you may be able to switch to SD right off of the stock ECU. good luck.

PS: is the dejon gt35r pipe the ONLY solution out there (i searched--even the ebay cheap stuff) other than using an anemic 3" pipe? it's all good if you don't know, just thought i'd ask.
