Here is a video of my corvette on the dyno. I am going to put a full exhaust on it and wanted some before and after numbers

84 corvette dyno 3rd pull:

 

What mods have you done to it already? I like the matching red intake btw.

 

I have trick flow heads powermax 2040 cam and first tpi intake

 

Must be a stingy dyno. The dyno my car was on is reportedly hard to give up numbers but I'm running iron L98 heads and unported tpi and pulled similar curves. I would figure yours would've been way ahead of mine. Or do you think your exhaust is that big of a restriction?

 

I do think the exhaust is holding back 50hp but I think my cam is my biggest restriction.

 

Granted, I don't know what your heads are capable of but looking at the cam specs I'd agree with you that it's probably too small to take advantage of those heads. It'll be interesting to see the after with new exhaust.

 

Yes. I am toying with the idea of swapping the cam. I will install the exhaust then dyno to see what that brings then I think I will replace the cam this winter

 

did you change the intake to tpi 84 vettes had tbs my first car was a 84 vette

my current car

 

Yes I changed the crossfire to tpi

 

update number after long tubes and corsa cat back

289.60hp and 378.21 TQ

 

Now the heads are holding you back. You should be making well over 300whp at least at 5200

 

I think its the small cam. I have aftermarket heads

 

Vast improvment from the exhaust. No doubt that held you down.

But he's peaking at 4500-ish now. Sounds like the call of the LTR's. You'd know way sooner than me but I think the runner length is keeping him down. Hard to say with a FIRST though, I thought they had a higher rpm range.

 

They do. He can peak out at 6000. What's the specs on the cam and what heads?

 

The heads are Trick Flow 23 Degree 64cc and the cam is a powermax 2040 formally compucam I think with my mods that cam is to small and holding me back about 40 hp as well as a few hundred RPM

 

The first base flows 300cfm. The runners are 1.80 open. Those are way bigger than Edelbrock runners at 1.65.
