Well i finally got my 383 back together with the new "blower" cam in it. Its the COMP 288NX Hyd Roller. It ran 11.85 and 11.92 on the first 2 runs.

I will be updating my fuel system and getting my D1SC next month so i'm 100% sure it will be well capable of 10's, since that was my goal.

My current motor that i am running N/A:
Eagle 4340 H-beams
Eagle 4340 Crank
Speed-Pro forged F/T pistons
2 Bolt block modded with Eagle splayed caps
AFR 210 with 76cc chambers
Super Victor
Demon 750
complete MSD ignition

It got really hot on me though??? I have an electric water pump but it circulates the water too quickly. I need to sort out that issue. I might have the timing off too?? I know that it will be locked out and set once i get my S/C but where is the "right" place to set it at?

 

How much stall will you be running w/the supercharger, and what were your sixty foots for both runs....?

 

You sure? Which pump do you have? I have the 35-37gpm CSR setup and I am starting to think it may not be flowing enough and may switch to a 55gpm Meziere setup. Also what radiator are you running? Is it very thick? Is it overheating during the run at WOT or just driving around the staging lanes/return road?

Nice times tho for a blower motor on nuts alone.

 

I plan on going to about 3500 on stall. my sixty foot times were 1.69 and 1.70 using BFG D/R's 275/60/15. Thats leaving at around 1200 RPM's with 3:73 gears (which i will drop to probably 3:55 after the Procharger)

 

Thanks on the times.

I'm running a return from the top left (veiwed from the front of the car) on my intake straight back into that "heater core" return line on the radiator. With the cap off i can see the coolant flowing like crazy back in there. It's almost like i'm running NO t-stat because the hot water is going right back into the rad and back down to the outlet tube and back to the motor. I'm thinking i need a restrictor to let some thru but not all of it. I was kind of concered with just dead-heading all that water flow into the motor without having somewhere for it to vent to all the time....but even a belt driven one does that huh???

I do know i need a better radiator and fan set-up. Right now i have my fan (single stocker from my 305 days) wired to run all the time. And i'm using pretty much a stocker radiator too.

My car heats up badly on one run down the track! I can start at 180 at the tree and during my coast to the end its almost 200 in one pass!!!! Once it gets above 190 it takes forever to cool it back down from there. I drove it straight to the track and it gets to 180-190 quick and hangs there if i'm moving down the road. That was another reason i thought i might have too much timing in it. This car will be street driven as well (to and from work 19 miles on decent days)

 

Thats not horribly hot considering the rad/fan you have but does seem to be heating alot more than it should. Abit better rad and alot more fan will do wonders. how much timing were you running? Shouldnt need much. Did you verify air fuel ratio?

 

Negative on that air fuel ratio check, but i think it might be running to lean (DANGER) and causing the heating up issue as well.

Another thought was the fact that i'm still using the tranny circuit in my radiator and im usually driving around at speeds where my 3000 stall isnt even engaged. i want to completely run a seperate tranny cooler and not induce that heat into my radiator.

 

That is not causing a cooling problem. I would check the timing, the hoses, and see how the radiator looks inside.

 

Wow, those are some very solid sixty foots w/out the supercharger even being intact yet, not to mention at just a 1200-RPM launch, very nice! In terms of your heating woes, it sounds like you need to back your timing down some, especially after the way you described it. Other than that, there are too many other variables, because on very hot days alone, your engine is going to run much hotter no matter what you do, even with the fan(s) constantly running. I hit 220-degrees just idling in the pits two weeks ago, and both my fans are set to trigger at 180, but it was 90+ degrees that day. If bringing down the timing doesn't help you any, then get rid of that stock radiator in favor for a better one....

 

My car does seem to launch very well on BFG's. I even have a pic with the left front off the ground about 1/2". I'm going to disconnect the vacuum advance and just rely on the mech. adv. since it set it at 12 and once i hook up the vac/adv it shoots to 20-22 and once i rev it up it goes almost to 40.

The radiator and fans will be bought just as soon as i can get rid of my R/C car that i'm trying to sell (kinda hard to find someone to dump $1,000 on a R/C car, like i did!!!)
