And here we go again. I really don't care what you say about my claims of a 12 second det on street tires (@114+mph)...We did the engine January last year He never had a problem with it (and it's kept at 15psi daily driven).</font>
Okay lets clarify...I can probably run a high 11's on a T28 and 370's. But it's not safe and it's not going to last. I don't necessarily doubt you ran that time but I bet money the car was at about 13.5:1 A/F ratio and the turbine was so constipated that there was about 50psi of back pressure in the manifold. These are engineering facts that can't be gotten around. That's not healthy.
I don't know if you are on the list but this has been beaten to death by knowledgable people...one who designs the danm turbos we use!
When I say safe, I'm talking Ryan B's over 100,000 mile motor that *will not* blow up after being boosted to high hell since 60,000 miles and nitrous'd before that.
Three or four runs down the strip may not blow the car up...but then there is that one time...boom.
A T28 will support about 250whp safely. Shaggy managed 280whp and about two months later we got an email that his turbo self destructed and fed the motor shrapnel. Bye bye DET, bye bye everything.
It's just like the guys with the JWT 50shot who put the .46 jet in (75hp) and say "hey my EGT is fine, all is well" until that one time the burn a valve because the car is running on the edge.
If you want to roll the dice and run the car to those unhealthy levels so be it. The car will not last and it's not designed to be run at those levels. It's ghetto to run it that way.
<font face="Verdana, Arial" size="2">If you have the 444cc injectors, the GTi-R nismo fuel pump, and the T28 turbo, you can generate well over 300hp's, pending on if you have a good engine or not. As a matter of fact I have my father's GTi-R set to 18psi of boost with no problem.</font>
I'll give you this, 444cc injectors, and a non stock fuel pump will go a long way to help the car live at those levels but it's still overwhelmed to put down a 114mph run.
On a 2700lb race weight car including driver (Pretty light) it takes over 320whp to go 114mph. That's not chump change for that kind of fuel system, and I fine it almost impossible to do with a T28 unless you got it hogged out beyond belief, but then it's heating the air so much the car will be very unstable.
What kind of MAF are you using? The stock DE MAF will in no freakin way even try to support anything over 240ish hp. You must be tuning with fuel pressure after that.
I'm not trying to bust your stones, but there are a LOT of people who are engineers by trade, and design the very stuff we use that have gone over this time and again. Not to mention there are lots of people who poo poo'd what they said and eventually blown their motors. It's not uncommon.
I don't like rolling the dice when running my car.
