It was a pretty night about 58 degrees and the beast was feeling real frisky. So after much rumbling I agreed to take her out Here is a video of our dance. Some one had commented earlier about not liking the sound the V makes with Stage1&2 intakes. The guy the beautiful beast was dancing with did not like that noise either!:glol

By the way, is that really you?!

Its me this is/was the third trip to the strip. First trip was a 13.5 (had traction controll on and standard auto) second trip was 13.2 (performance mode standard trans)
I finally figured it out on third try the 12.5 and 12.4 were both with sport mode performance and power brake to 3,000 rpm.
They have open track Friday night and Sunday afternoon $10 to watch $20 dollars to race sign a release and drag all night against random cars. The 12.5 run was against a dyno tuned z06 2006 vet took it by about 2 links. Fun Fun!!:party amazing what 407rwhp will do. There was a Lamborghini out Friday night based on his time the V would have hurt him bad. I think it was a trainer model.

Woo-hoo!

What a ride!

:party

Makes a person wanna sing ...

Born to be wild .....!

Floyd,
I am still currious as to what tunner program was used to do your tune?
Did they give you a CD copy of your tune, incase you were to need it in
a different part of the country?

CONGRATS!!!!

Do you think there is more to be had with some fine tuning and more driver runs??

The program used was LS2. I don't have a copy of new settings however the change from factory was so slight that a return to origional GM would not be a big deal. The reason I took it in for a tune was after of install of intake (stage 1 and 2) it was throwing a too rich code occasionally with hard acceleration. I had F/A checked at a second shop to be sure was not to lean.

I think I could get to 12.0 115 with a different intercooler setup. I want to install a fan but have not gotten to it and wonder if 2009 will give us a 550-600 HP xlrv.
The number of street cars that show up that can turn times like this are mighty few. Is a blast!!

RedV............takes a bit of HP to drop down to 12.0. The gain your looking for will need more than the intercooler setup. I do however have an idea if you don't mind loosing a little top end. The vette's have two choices for gears in the rear, if you go with the shorter gears you would have a screaming banchee on your hands. Cost would be about $3,000 unless you know someone to change out the pumkin. You would be in the mid elevens with this set up and about 3.9, 0 to 60. I'm only guessing at these numbers based on my old dragstrip experience back about 100 years ago.:glol :glol I think I could get to 12.0 115 with a different intercooler setup.

I don't know they don't time 0-60 at houston strip but with a 12.4 1/4 mile I am guesing I am at 4.1 0-60 right now. I don't know if I cold get to 12 flat but I will let you know next time we get a night with temps in 40s. Don't happen to often in Houston.

You have an advantage of the humid weather in Houston. You will get faster runs in humid weather. Takes a lot of mods to get 12.4 down to 12. Gotta do something big to get 4 tenths off that run.
Do you break loose on the line?.............If you do put your shifter into the gate and push it up to second gear. stomp it,...........and the minute you think you have one revolution on the tires, kick it over to D and let it shift itself. I used this technique a long time ago with just an automatic and was NEVER taken off the line by another car in my class or for that matter by any street eliminator runs.
Tenths don't come off your run without big dollars being spent, that's why I suggested the lower gears. That would be a big bang for your bucks. I remember changing gears to 411's and then to 357's. I thought I had a lightening bolt by the #ss. That night I went to Lions drag strip in LA and beat Mickey Thompson, Don Nicholson and a bunch of other no names and won street eliminator. The Ford fans almost tore down the stands.

Inrteresting...I was under the impression that the ideal combination for internal combustion engine was cold dry air. of course low elevation.

Hmmmm, me too. . .

Cold and moist is the way to go. In fact, water injection systems were quite the rage and are still looked upon as a way to both cool the air charge and make it more dense.

You are correct. Humidity does nothing more than displace oxygen from the air,and less oxygen=less power. Dry, cool air is the best.

Nice to see an XLR-V being modded/drag raced. I'm in Houston too...next time you're going out, let me know, and I'll bring my CL65 AMG out to play. That would be a good matchup!

This seems to explain water injection pretty well. This is from web site of methane injection manufacturer.


Will water injection increase my horsepower?: Yes, but not directly. Water injection works to eliminate detonation, also known as knock. The big gains come from the ability to increase boost as well as the full ignition advance allowed by the ECU when it does not detect knock. While the cooling of the intake charge will produce some power increases, those increases are cancelled by the charge space occupied by the water vapor. In other words, there is slightly less room for air and fuel. However, by using up to 40 percent alcohol with the water, additional cooling takes place before the turbo, and the alcohol works as a fuel in the charge. This results in an increase in power.

You will notice that any increase in charge arrived by cooling is lost due to the space occupied by the water molecules. If you can get the cooling without the water you get the best results. The alcohol boosts the octane to about 110. This is where the extra power comes from.

Yea, I guess I should have included cold and low altitude (density)with the moist air. If you would have watched the drags at Fontana last weekend, as the sun set the times got better and most had to peddle it down the track because they wheren't set up for those cold conditions. Most dragsters where running 330 to 335 MPH in 4.2 and 3.

Hello Red, we've test and tuned our STS-V with the new modified s/c lid with revised ECU tune and gained over 25 rwhp and 16 lbs of torque. I think this modification could definitely help you get closer to that 12 second flat run. Let me know if you have any questions.

Craig

Is that th result of lid alone or does the 25rwhp include the pulley effect?
