Nonetheless your car should be running mid 135mph with that kind of power. Obviously your car wasn't working properly.
No, actually it shouldn't. Do the math, a 3800lb car + driver will no way do 135+ in the 1/4, I don't think you realize how much weight that is. I made similar power to him a year ago and got the same time with a 2.0 60', got it down to a 1.44 the same night and it went 10.63 at 124MPH, again 654RWHP in a car that weighs 3966 with me in it.

My car went 133 with 773RWHP and should go a little faster with the power I have now, again, I just don't think you understand how much weigh plays a factor. To help you out, the Veyron has 1000HP and runs a 10.3 and weighs 4000lbs. I'm close to it (in regards to weight/power) and went 10.02 losing the blower belt at the 1000'.

Not saying this is normal or what you can expect but he somehow does it.
WOW... 717hp and running for two seasons is a LOT of WOT runs. I wouldn't put that many WOT burst on my motor in five years!!
If the rod bolts hold, I feel somewhat comfortable that with a good "rich" afr, conservative timing, combined with my meth injection, my ringlands should last until they go.....

A rich tune can smoke your ringlands too. Ask the nitrous guys

Except I think that may be a little too technical to explain in this thread full of experts lol.

Hope your car weighs 5,000lbs because something doesn't jive.

I was about to say the same thing. On a TTI 60 trim went 11.4 at 117 and that was with the car pulling timing at the end of the run. Of course your 60 time probaly has a lot to do with that time.

I obviously misunderstood.. I thought we were talking race weight.. A race weight of 3800 lbs (or very close to it) isnt "hard" to do that.. An easy task? No, but no where near VERY difficult.
My race weight is 3550 (I know, 250lbs off the 3800 mark) but with a decent shot I would *easily* hit 10s and should be at the 130mph mark. Honestly not sure on the mph because it doesnt matter to me..

I was thinking "rich" in PE of around 11.6-11.9, with conservative timing, while of course 14.7 out of PE.

I've run N2O on everything from jet skis to Vettes in hp levels from 40hp (jet ski) to 250hp and have always aimed for 11.5 afr and have had great luck over the last 25 years.
This is my first FI car and just trying to do the research.

Gotcha. I think you will be fine with 600+ rwhp as long as the tune is spot on. My first turbo build was tuned by the same tuner AVENGENCE uses (and I still use good ol' Rick) and I made 650rwhp on a stock bottom end. Ran ~5000 miles until it somehow hydro locked and bent a rod. Long, weird story.

Yea probably so, but a weight difference is still substantial, from my experience to trap 130 in a 3550 car you need about 610RWHP, to do it in a 3800lb car, you need about 650RWHP. Which honestly sucks, lol.
