Highest NA RWHP?
Most people who race ask for a more aggressive setup. Usually that means more compression. Therefore not being pump gas friendly. Also depending on where you live will cause your compression to be lower or you to run less timing on HOT DAYS. Well I live in Florida and Futral Motorsports made it a point to keep my compression safe even though I told them I can reduce timing with the timing tuner. I even suggested running a bigger cam to bleed off compression, but Futral Motorsports told me to stick with the original plan. Which was building a potent, idle perfect, street car. Well that is what was delivered to me on June 22nd. Am I picky? Yes, I drove around with my scan tool and verified my timing was 28 degree's at WOT. No KR on pump gas in Louisiana. How do I know? I filled the car up. I drove the car all the way back to Florida using 93 octane and I saw no KR. On day two of having the car home it was especially HOT. To be exact it was 97 degrees out at 1pm. I took a friend for a ride and we both could hear knocking when I hit 5krpm on a quick blast. I pulled out my scan tool to verify. I saw 3 degrees retard. I got out of the car and used my nifty timing tuner and reduced timing to a MAX of 6 degrees. I forgot to mention I had already reduced timing that morning because I knew it was going to be hot. Anyway, I took my car for another blast and no KR. It drove perfect on 22 degree's of timing on a VERY HOT Summer day. My compression is 11.7:1. My cam is not much bigger than the Trex that is going in 346's. Allan Futral wanted to keep the low rpm tq high to maintain driveability and reduce bucking below 2krpm. I have 3.73's and I think my old 4.10 combo would have been perfect for this setup NA, but on the spray on the street, 3.73's are better.
Basically what I am trying to say is depending on the combo, location where customer lives, finances available to customer and integrity of the engine builder/tuner will determine what is pump gas friendly.
And I'm not one to play the dyno queen game. As long as my car gets down the track faster than the guys in the next lane, I don't care how much power he makes on the dyno.
My point is that if you're going to build a motor that's going to require a mix of 103/93 to go to WOT on motor, you might as well build a motor that's going to take 116 to run. Why not run 14.5:1/15:1 compression and make much more power?
The car isn't mine. I have done some work on it. I will probably do some more work on it when I get back from summer break. Part of the part that I worked on was responsible for about 20rwhp in a good way
They are estimating that the car will run 9.30s at worst. It has run within a half second of that before...
Hmm... Should have that covered
Im pretty sure I know who it is now, if so, really looking forward to seeing it run it should be badass!

I know of another one that is not around here.

My car on 22 degrees of timing and pump gas is still making over 500rwhp. I am the one to play the dyno game because I built the car for the streets and not for the track. The dyno is a tool and just that. Building a car that runs ONLY on 116 makes no sense in my case. My car see's much highway time. The last time I checked you cant get 116 at every gas station.
I guess all the 03/04 Cobras I run into that have two programs for their cars so they can run more timing when they race do not have street cars. I guess all the guys in our FI section that take measures to prevent KR do not have street cars. I could go on and on, but like I said b4. If you want to see what ALL the high dyno'ing cars really make on the dyno on pump gas you have to get them all together at the same location with an independent individual pumping 93 octane into each car.
"well, i know someone that can kick all your asses".... IMO spill it or delete the thread
as for this dude running his mouth about "someone elses car" - who gives a rats ****. unless YOUR car can back it up, shut it.
- rant off.

Vinces car is most certainly a street car. It was driven home from Louisiana to Florida with the AC on getting over 20 mpg and will idle at 950 rpm. Id say thats a street car.
As for the hot weather here in Florida....yes...its HOT right now. If I could take a few degrees out of my stock 2.2 liter GMC Sonoma I would...its pings daily right now.
Vince is just smart for having some control of his motor and keeping it safe.
you were'nt very specific, but this c5 we back halved has a c5r engine in it.. vette doctors did the engine,we did the car.. heres a quote from carmen of the vette doctors off the corvette forums...
"This new set up makes over 650 rwhp With 488 rear end gears. The converter is still not what we want so that's more testing we have to do. Our goal is to put this car in the 8s on motor. Then we will be on to the juice."
