Shakedown on D1SC, 10.20 @ 134.16 well been working like mad on this car last couple weeks. since march 9th i built a fuel system, swapped cams, and put the blower setup on the car. balancer was slipping some so last nite I pinned the balancer to the crank. put the dynojet wideband on hte car this afternoon and went racing
its opening week. NO prep. track was an icerink all nite. only made 2 full passes, first two were half track hits watching the logs. I was blowing the 28" et drags off the car for 100+ feet every pass. footbrake only, no Transbrake tonite. was running just my y pipe and nothign else.
We tuned VERY conservative, getting a big more aggressive as we went. but of course i had to stop after the 2nd full pass, ******* POS header hookers..last year I blew two of the EGR things off, and tonite on the last pass the last remaining one blew off, ended my nite, really pissed me off, based on what we were doing tuning wise, car had a 10.0-9.90 in it tonite no problem.
last pass was:
60': 1.54
1/8th: 6.547
1/8th MPH: 108.14
1/4:10.201
MPH: 134.16
I was seeing 10 PSI with the air filter on. the 10.2 pass I pulled the air filter off the blower. track was REALLY done by then, I was skating down the 1320 and didn't look at the boost guage, so not sure what I picked up, by my AFR didn't move hardly at all, so couldn't have been much if anything. obviously 10 PSI isn't much, need to improve the boost.
goal was 10.1-10.2 @133-135 so car did what i wanted first time out. ran the car on 112 leaded BTW.
IAT's were 150 degress on the big end. I refuse to cut my bumper up, and have a pile of N20 **** laying around, so planning on plumbing in a 25 shot or so to cool the air charge instead. car was at 200 degrees all nite, needs a thermostat(still on stock one LOL)
last pass AFR was 11.3, timing like 16 degrees, etc. like i said was working up to more aggresive stuff, but then busted that bastard header. i can't believe what pieces of **** these headers have been, so frustrating. i'm NEVER buying another fuckign thing from hooker in my life.
all in all i'm very happy for the first time out, and for doing so much work in little time, seeing it all coming together and working right was nice. going to try to be back at the track next week sometime and shoot for some 9's boost only and hopefully have the N20 on the car to try and cool that air charge down and see what I pick up.
huge thanks to my friends, especially Timmy2Stage, KP for his advice, and of course my badass sponsor of many years now Speed Inc for all their support in rushing parts to me at the last minute all the time, those guys have never failed me in 6 years and I know never will.

those IATs are a little high for the weather you were in, in 50 degree stuff I usually dont get over 120 through the lights. Usually see a 40 degree rise in the 1/4 mile but since you only have a 3" core IC thats about right what you are seeing if you dont have a lot of air flowing across it.
Not bad for the first time out, take advantage of the cooler weather because it will get slower as it gets warmer, boost will start dropping off as the temp goes up..

Ice skating rink is correct 
The car finally found the groove at the 1/8th mile 
The tune I have in there right now is very friendly to your motor
Next time were out we'll slap it around a little bit. IAT's were getting hot at when 3rd gear was clicked. Sean refuses to cut the front bumper to let air pass through the center of the intercooler. So it's time to cool the air charge off with a little N2O. Just enough to keep it from seeing anything over 100 degrees. But we'll see how much it takes to get the aircharge to an ambient temperature.
It was a good time except for all the idiots who own catelope shooting ricers.

yup. 4X4 trucks shouldn't be racing, i don't give a **** what their reason was. some of those guys had mud in the wells and big knobby tires. what in the ****.
Kev we were seeing almost a 60 degree rise in my IAT's over the 1/4 mile.
yup. tune on that 10.2 pass was the "no way we're gonna blow this thing up cuz its so safe" timmy2stage special car has alot left in it in many respects.

Maybe a air to water intercooler would work better if cutting the bumper isn't an option, for street use it would be probably the same or maybe a little worse, but at the track with ice I'd think it would work better.....just a thought.
Nice times tho, especially for the first time out with a new setup!

The air to water unit would probably be the way to go, no air flow concerns so no butchery needed on the car for that, and you can certainly get the intake charge cold enough that way too. Meth spray may be another route, you could use the washer bottle as the tank for the meth, and run no intercooler at all if the meth would drop the intake charge low enough... lots of possibilities that would need no air movement, and are probably the same weight or lighter, at least in the nose of the car. If the air to water gets the nod, the water tank coudl go in the trunk, so the weight it adds would actually act like ballast as well... and from the sounds of the track you ran on, it may even help.

A water to air intercooler ins't an option right now. We'll be putting the kit on the car next week. The converter will be good to 140MPH. Anything over that then it will need to be cut open. Final trap RPM was 6600rpm. Factor in that the car was being short shifted on the 1-2 because all of the tire spin. On the 2-3 it was shifted at 7100rpm. Once the car is hooked and shifted at the right rpm Sean's car will see every bit of the power band.
Keep in mind this was just 2 full passes, time was limited at the track and I had about 15 minutes of tuning into it before the track
I really think the car has .4-.6 tenths and 5-7 MPH left in it. Once the IAT's get back down to an acceptable level there should be a 2lb. increase increase in boost, once that happens then I'll add the timing back in.
Just into 3rd gear there was 10lbs. of boost at the gauge. However, IAT's were only at 111-113 degrees. By the end of the run they were just over 150. I believe at the big end there was no more than 8-9lbs. of boost.
First time out with the car. It went great. Next time it will be buried in the 9's
On a side note, I do believe that Sean went quicker than ProStockJohn compared to his first time out with a new setup With half the boost

thanks everyone, much appreciated
lol the only jab i've been giving PSJ is i did a 180 with my setup in and am making 10.2 passes 3 weeks later, takes him a year to get a car to the track after just changing the oil
bottom line is this car has a buttload left in it. hell i'm hoping i have to have the converter sent out and restalled if it means i'm going 140 plus
car is a bit heavy now with this blower. probably going to have to ditch the leather seats(i had both front leather in last nite) etc.

Nice times, have you thought about a CO2 sprayer for the intercooler? I think that would really help your IAT's.
