Static compression is 10:1 all mods are in my sig just like to share what do you think of the
E.T Expected with an full weight T/A and 200 to 250 of NOS
433 RWHP and 420 RWTQ

 

Great numbers man.
WHY Didnt you raise the compression Littel more?

If you have a good rearend I think 9s are possible.
Good luck.

 

Was the convert unlocked?

 

Yes I don’t think the stock rear will hold

As you know its very hot and our fuel is 90 octane and my future plan to install a single turbo.

 

no it was locked

 

Really need a lot more info to know if those numbers are good or not. I am personally hoping for 480 rwhp unlocked with my 383 but I have every bolt on possible and a great set of heads.

 

Tell me about it its so damn hot here I even parked the car in the garage last week I dont even wanna drive it even with A/C.

 

See my sig for more info and the car is a dally driver (full weight)

 

I too thought 383 would have made more power. 10 to 1 explains a lot though.

 

Why is 90 octane the highest you have available, that fuel source is robbing you of a bunch of hp. How many degrees of timing are you running?? 20 at most ?? Just curious. I bet she comes to life when you put the turbo on it. Good luck.

 

Actually ran 26 deg with that fuel and 0 ping we do have most racing flues (VP and torco) but is a bit expensive for a DD car.
I did the dyno with less than 200mile on the engine the car feels stronger at this time
After 600 miles and the temperature is normal even in heavy traffic.

I think it will have some more pones the next time it visits the rollers with
A tune for spray

 

I think it's good bro! More than mine! That's what numbers I hope to put out with a 90/90 set-up. My old numbers were without the ASP crank pulley and only 750 miles on the new motor. Should be 395rwhp right now.

 

Thanks man I also compared mine with a similar 383 on a C5 he’s has a bit more.

 

Great numbers

 

I think the numbers are good considering the smallish cam/heads combo, convertor and 10:1 compression. Get some track times!

 

Derrick,

If he put a bigger cam in there and your heads on it it would pick up ALOT of power.

Not bad numbers for the combo.

 

The track is closed for summer
but the car feels like it had sumitomo's
and the blue ovals are ignoring me


What cam/head do you think will give me the extra power for my DD bird?

 

What's his combo?
