I presume that's with no cooler (as mine was).Quote:

i think you would be sick if i told you........we have run as much as 31 degrees at full boost!usually around 28-29 at boost...brodix heads NEED alot of timing!Quote:

I'm running cast iron street heats with 28 degrees timing. My EGT's usually 1580-1640 depending on air quality. How about yours?Quote:

Air to water is amazing. I'm glad you posted. Just this week, I was pondering whether to scrap air to water for the convenience of air to air. But your charge temps say it all.Quote:

How many gallon water tank would you recommend? I was thinking of a large bilge pump, and using 3/4 inch heater hose. Everything else in the car is high dollar hose, and I thought for the I/C I wouldn't need steel braided. Any particular GPH required for the water pump? Do I need to put a screen inside the tank to prevent ice from clogging the pump? Are plastic tanks better at keeping the ice cold, since they probably don't sweat as much condensation?

I just looked at your car photos. Looks like a bad biotch. What are you getting out of it? Are you going to bring it to Orlando for FFW Spring Break? If yes, what class would you run?
Greg, I have not had a chance yet to test the dyno findings at the track. I think it would similar. I am running a 10 gallon aluminium ice box with a screen. I highly recommend using a screen for two reasons. #1 it will help prevent the ice from eating away at the pump impellar blades ( this could reduce the pumps capabilities) #2 the pieces of ice could make it into the water side of the cooler and flatten out the fins ( this could reduce the cooling capabilities of the cooler).
I used an12 rubber hose that just pushed onto "push on" an fittings. I can shoot a photo of my pump ( bought from Grainger for approx. $130.00) and how my lines are run.
I actually run from the tank, to the pump, to the indash cooler, to the tranny cooler and then return to the tank.
Blown347hatch, thanks for the comments. Sounds like you have a nice ride. I have not run the car on the strip since the conversion (powerglide, 10 point, chassis and suspension upgrades). If i can get the FAST seq on soon we might bring it out to Orlando. It will probably be with the 302, i don't think the 345 will be done yet, so i would probalby just run true street. I am hoping for 800-900 @ the wheels with the new 345, FAST seq and YSi.
I will look for you out there. Thanks for the tips. True Street is a cool class. I ran there in that class last year. Posted a 9.20 and was the 7th fastest. The fastest guys are the turbo cars (go figure). What are you hoping for? Looks like something in the 8's.Quote:

I am going to have to setup the susupension and go through some trial and error on the torque converter. If the car is not set up right and i'm not going to come to FL and make some half *** pass. Like you said there are far too many fast cars there. What trans are you running? If auto what is your stall? (stahl?)
I have PA's Supercomp C-4. I also have their 9 inch converter. If I take the low side chip out of the 2-step, it will stall to 5200. I leave with a 3800 chip. The last time out, the cold air made the car find some extra power, and it wouldn't stop standing straight up. I smashed the hell out of my headers, and didn't get a full pass that night. My balancer split from the YS-Trim and the Cog set-up. So, the motor's at Ronni Crawford's shop, and turbo here we come. I'm hoping for low 8's after working the bugs out. It will have a air/water intecooler, 4 inch tubing. 91mm turbo. I think power won't be the problem, going straight and keeping my pants clean will!Quote:

I am running a 9inch with stall to 5200 also. The new YSi makes a but load of torque early so i think i am going to change up the converter.
Yeah, i imaging with the 91, and a matched head/cam setup you should make about 1100-1200hp to the wheels. Hey, who the hell want's clean pants.......oh, nevermind. I forgot about the Honda Drivers.
You hit it right on the head as for the plans to switch to a glide. It's supposed to also soften the hit as little with the 1.76 first gear. What is the C4's first gear? Something like 2.40 or 2.60? I am going to take some shake down passes on the C4 before switching. We'll see if it lets go.Quote:

Do you think I can get by without a wing on the back?
Wolfe racecraft 10 point with through the floor subs, window net, etc..
As for the wing, I use the rule that if you are near, at or above 150 mph go with a wing. I think you are at the point that you should seriously consider putting a wing on. You may not think you need one right now (seat of the pants feel) but with you new combo i'd imagine you are going to need as much rear down force and stability as you can get.
I put a Racecraft Inc. wing on mine. It's pretty clean. Having it painted right now to match the car.
It sounds like you will also be limited to 8.50's with your cage as well. So, without the wing, are you saying that the car may be more inclined to spin on the top end? I've gone to great lengths to keep the car mild as looking as possible. I know the chute is going to hurt that look though. Do you still think you are going to Orlando FFW?Quote:

I understand the mild look. I'm not saying the car is going to be unstable, i am just saying it will be more stable. Sounds kinda stupid, i know. From what i understand aside from the downforce, the wing extends the deck surface which adds in a smoother transition of the air going over and under your car. With a smooter transition at the rear of the car the air is less turbulent: less drag and a more stable rear. I'm no expert but that is the way i understand it. If you get a chance take a look through a few websites, magazines and chassis shops. Heck, you may even want to talk to a few folks. You will notice more people run wings than not. My experience is that they do run the wings more for that added stability than for the cool look.
I hear ya. So, are you still on for Orlando? If so, I'll look for ya.Quote:

No $h!t! The weatherman also hates my guts. I am almost guaranteed to make rain whe I show up at a track. Last year, I sucessfully managed to cause a rain-out to be called at Spring Break Shoot-Out last year. This year, since I am not running my car, I think everybody should owe me. ;)Quote:

Yeah, we'll have to get a pool going just to keep it sunny. I'll keep you posted on my progress to see if i can make orlando.
Later.....
