With every bolt-on imaginable and a healthily streetported S5 TII engine. Only things that were still original were the ECU and turbo. The porting is where it's at.

 

I was going to say: "it needs to be ported and have everything you can bolt-on."

 

I did 250rwhp/250rwtq as well on a heavily streetported s4 motor with s5 turbo... i think it was maybe 12psi

 

You made the same HP as TQ? Weird...

 

I dont know, my car doesnt seem to mind 400 much, at least up till this point. And its the model of reliability...

Maybe building your engine right has something to do with it?

 

A BNR stage 4 won't get him anywhere near his 450whp goal. Not saying it's a bad turbo, but it simply can't flow enough to make that kind of power.

 

Gotta agree, I only managed about 390 or so out of my BNR 4.

 

thats exactly what i had, PLUS a full standalone, and 13 psi. are you talking wheel hp or flywheel?

 

So you were ported then? Because if so, you should have been making more than 240whp on 13psi. Sounds like you had issues to me.

 

hey Erik ? for ya man.....how do the N/A rotors do with that setup? hp by any chance? cause Im about to rebuild my block n I thought about using N/A rotors but I dunno if that would be a good idea for what Im going for :/ any suggestions?

 

to the original poster if you are still looking at getting a t70 and don't want to pay for a crazy expensive turbonetics etc... but don't want to buy a crap turbo then there is an alternative. PM bobybeach on this forum. He sells Masterpower turbos that have been proven over and over again. A t70 usually goes for about 500-600 bucks wich is way cheaper than a turbonetics t70 and it lasts just as long. Good luck man.

 

That looks like a good turbo ....

what would you recommend for around 350 (At no more than 15psi) to the wheels that would be good for autox?

What does that one you linked to cost?

you never answered my question, did you make 250hp on a dyno? to the wheels? do you have a dyno chart? The only 'issue' mine had is no trailing ignition, which cant account for more than 15rwhp and i think even that is a stretch. Yes, the engine was ported. Also, it made peak power at only 5500, before the boost died off. 13psi was peak boost, it was only there for maybe 2000RPM's between 3500-5000. I dont see what more can be done to make more power unless you magically found a way to make the tiny stock turbo carry more than like 7 pounds of boost to redline. Also, in the dyno section most people with stock turbos and 12psi made around 220-230 wheel.

 

you know I actually ran into a forum lastnight where he was talking about them a bit, and other people on that threat were saying nothing but good things about it so yea I think Imma be trying to get in touch with him pretty soon here......

so how bout those N/A rotors for a turbo set up? anyone...opinions, complaints, ideas?!?! lol

 

/\/\/\

 

you will hear people argue this to death both ways. you just have to decide for yourself. the most popular thing to do is run 9.0:1 rotors on boosted engines, its also safer/easier to tune.

 

agreed. I didn't want to touch this subject with a 10 foot poll because it does cause a lot of fighting but just to let you know I've talked to many a tuner out there and they all say stay away from n/a rotors if your looking for big power. If your looking for a fun street car than sure use em' but really high compression rotors with a big turbo is just begging for troubles.

 

yea i settled for the n/a s4 rotors with my MPT70 setup. i can hit 30psi by 5200 rpms. but i also have a bridge

 

damn what hp where you seeing? what gas where you using? any alky injection? How hard was it to tune it? How long did it last? Got any time slips? Was it a half bridge or full bridge?

 

What fuel management are you using?
