Made a few hot weather passes yesterday..
One bad thing about blowers vs heads/cam/nitrous is the heat. Nothing knocks this car down more then high air temps
But I wanted to check out the trans brake I just installed and I have had this nagging problem with trans fluid coming out of the vent when I'm hard on the brakes after a pass, even with the trans a quart low on fluid it still did it pretty regularly. I installed a CSR transmission overflow can on the firewall so i wanted to see how that would work out.
At nearly 4000' DA (87 degree air temp), leaving the car rich and zero track prep I still managed 6.18-6.24 @ 114 or so in the 1/8 with 1.42-1.395 60's. I can leave with like 6-7psi on the brake instead of nothing off the footbrake now which should help a bit when I get on a good hookin track. Car ran 6.50 @ 107 last year in the same weather and it was over 100lbs lighter so its doing a little better then last year.
Cool thing is the annoying trans leak is fixed, after 5 passes in an hour the trans was as hot as it will ever be and not drop anywhere, nothing sucked more then smoke billowing out from under the car when stopping after a pass and wiping that mess up under the car.
Couple passes from yesterday, I'm going to put an electric water pump on it so I can cool it off quicker between rounds but other then that I'd say I'm finally done for a while. When it cools off some it should get in the 9.20s in the 1/4 I think, not going to beat it up in the heat to get a new best so I'll bracket/6.50 index race it until it cools back off outside..

That's so impressive! Glad to see you have that stuff fixed. I'm at the point of just following your build with some minor changes to race that Car Craft Street Race class since it seems deadly consistent and good enough to go a couple rounds

KraZy, noting wrong with a 400, they are just big and heavy. Good thing is I can build/rebuild one in my sleep and they can take a whole season of abuse in stride. But so will a powerglide except a glide isnt as heavy, I'm just too lazy to switch to a glide to see if it works in this car though.

The funny thing, is that I wonder how things will be for next year, in regards to parts allowed. Like if they will allow the Dart's in along with the AFR's and the Edelbrock stuff.
Add a 78mm fast/78mm fast TB, do you think it'd would help at all over the LS6 I thought you were running now?

Very nice times by the way!

I think kevin is trying to maximize his combo while not spending so much money that it would be more feasible to change blowers etc.
Awesome times Kev. Dont tear it apart until we get a good cool snap...see what shes got!!!!

I could do meth but I have had some bad experiences with it in the past, its fine for a street car thats tuned on the safe side but trying to tune close to the edge and be consistant as well seems to be a bit of a pain. Even though I will admit I never tried one of the newer proportional systems.
Plus this IC is about as efficient as a house brick I think, its great when its cooler out since its a big heavy heat sink and will stay cool for a while, but once it gets hot it stays hot for a long time as well.
No doubt an A2W with would be the way to go but thats another tank, pump hoses etc. Be easier (and cheaper) just to hit it with a 100 shot of nitrous

I hear ya Kev, doing your own work really saves the wallet, plus its sooo much better when you reap the rewards of an awesome performing car.
It'll go 8's in cooler weather, i'd just leave it alone and wait for fall to come around....I hear there is a green T/A that might go 8's as well.....be a nice race procharger against turbocharger
Keep up the great work Kev, a ton of us really look foward to your progress, it gives us something to look up to.

I dont think it will go 8s with the D1 at this weight, I need to do something with the fuel system before it gets down there. I dont think anyone has gone 8s with dual in-tank walbros..
