Im not sure what your saying. If you think the stock 370cc injectors can flow more than 250whp, well they wont. Even injecting meth/ water wont make the injectors flow more. That stuff is a boost cooler!docktercolin wrote: cheap HP....... Money is kinda tight right now.........thats the way i like it. Blow it up then i have to rebuild bigger and better.........

You mean to tell me that you were trapping 114 in the 1/4 with a gt28r??? At 14psi??? and only 250whp? What were your 60' times?supreamS14 wrote:
Take it from me, I KNOW! My sr has a gt28r, It felt really good @ 10psi. I ran some 100octane race gas at the 1/4 mile strip, bumped up the fuel pressure 4psi and the boost up to 14 psi. I made at least 16 runs. Well on the 17th run or so my boost spiked to 16psi and melted and cracked a piston running 13.0 @114mph
@ 10psi I was running 13.9 @14psi I was running 13.0 And it felt good!
Im guessing @ 14-16psi I was making around 250whp
My last words would be to ask a local tuner that dyno tunes cars and get their thought's on that set up.
14psi spiking 16psi. That was my fastest time and my motor poped right at the end and I was running sunoco 100 octane race gas. I was guessing my whp and I cant find my time slip but I think it was around 2.0-2.2 60'. I just ripped threw my whole room trying to find my time slip. Its around somewhere.vanquish2 wrote:You mean to tell me that you were trapping 114 in the 1/4 with a gt28r??? At 14psi??? and only 250whp? What were your 60' times?
That trap speed is good for high elevens if you could hook.....but your time doesn't match you speed.....it would have had to have been like a 2.4 60'supreamS14 wrote:

You can see my sig and your numbers line up with what I've seen as well. Good job by the way! Which 2871 do you have? Who tuned your car? I currently run 25-26psi on my 2871 .86 on torco accelerator 107ish octane. When I ran my 11.8 I was at 338whp and 21psi on the same turbo. No meth yet....just a truboost to control the good stuffkentuckyslider wrote:As for trap speeds and times......... I had a 1.75 60' on MT ET streets when I ran the 11.7@117 but I had a 3.91 J30 R&P now I have a 4.36 skyline rear diff. I haven't ran the 1/4 with the new R&P but I had a 1.56 60' in the 1/8th with the same size wrinkle walls but a slower MPH and ran a 7.51@91. (91 vs 93mph in the 1/8th). The 4.36 and drag slicks make the car come out harder with much more midrange power but you lose mph from my experience. I will run the 1/4 when it cools down and we will see how it goes. I expect a 11.5 with a slower mph.
Question: My wastegate is maxed out at 21psi and I want to run water/methanol injection and take my GT2871R up to 24-25psi just for the track. My tuner said I need a new wastegate actuator to get any more boost for the methanol. ANY SUGGESTIONS????????
Are u running a lunch control? What are u launching at? My best 60' was a 1.9 on a 6k launch on j30 LSD and neogen tires. I avg 2.0kentuckyslider wrote:As for trap speeds and times.........

Only way is to get a external wastegate welded on. Less back pressure and no boost creepkentuckyslider wrote:I have the .64 ar GT2871. I want to get 24-25psi out of mine with methanol but my wastegate is maxed out. What do you do to get 25psi out of yours?
