Dyno'd the car today and was pretty impressed with the numbers.
I was only expecting about 165hp at the wheels.
My car originally was a 305TPI Auto rated at 195HP at the flywheel.

 

I would think with a Stealth Ram, headers and a freed-up exhaust you'd expect more than 165 from it, even on a stock 305 long block!

With a bigger cam to complement the rest of the combo (getting rid of the factory "peanut" cam), plus tuning, you'd almsot certainly get another nice bump in power again. Nothing earth-shattering- maybe just an LT-1 cam, which would still be a fire-breather compared to the factory 305 peanut cam.

What did you do different on run 3 to get that nice little bump in torque/power across the baord?

 

It sat for 17 minutes. Cooled down more is my guess

 

those dont seem too bad. does your car have the L98 cam or the peanut cam? cuz i figured an L98 cam would pull to over 5000 with stealth ram.

 

I gots the peanut cam.
and ya, letting it cool down gave us the higher numbers.

I figured it would be low due to the torque loss that I felt after putting the HSR on the 305.

 

So would you say the HSR is kind of a waste of money for a stock 305 TPI?

 

i think with the L98 cam it would still be a nice match with HSR

 

Just for comparison, Ian (iansane) had 225hp/249ft lbs with a 305/stealth ram combo with the LT1 cam. He probably has a bit more in the tune as he pegged the wide band O2 sensor at > 10:1 AFR. Gives you an idea of the rear wheel gains possible with just a cam swap

Wow that graph looks much better. Made good power all the way to 5k.

 

Wow, that's kinda surprising. I'm amazed at the torque difference between mine and yours, Zeph. Mine's down at 250 while yours is up almost 275.

Do you have any tuning done?

 

STIFFLER on this board got 227 rwhp with just bolt ons ...on a 1991 305 TPI 5 speed.

 

nope, no tuning done yet. I am just running the base ARAP program, and I believe that is an Auto prom. A few people mentioned that the Manual prom has more aggressive timing in it so it should make a little more power.

 

I don't doubt that for a second. CheezX on this board got 230 rwhp with just bolt ons on a 91 305 tpi 5 speed. His torque curve looked nothing like Ian's though - it was the typical peaky tpi wall curve. Peak numbers don't tell the whole story but those are definitely good numbers out of the 305 tpi in 91/92.

Not entirely sure why you posted that but I was just trying to provide a data point on what a cam swap could do since Damon brought it up, and specifically the LT1 cam.

I always liked your ride Zepher, that is nice man.

 

thanks, I appreciate the comments.

 

Just give others results on 305's what they got . thats all
