It's been a while since I have posted...

I've made really good progress on my '82 Vette. I have gotten the 0-60mph down to right at 5 seconds flat on a good day.

It's turned out to be a beautiful sleeper with a show car level repaint, OE wheels, and restored interior.

I have spent a lot of time on the tune and it runs quite well. No knock... runs 12:1 at WOT and 14.7ish in closed loop. From the CTS/IAT bias to proportional gains... I am very happy with how it runs.

Right now, I am running an 86 iron head Vette SA table with PE added spark that gets it to 34 degrees.

I want to wring just a little more out of the car, so I am upgrading to AFR 916 heads with 65cc chambers, hydraulic flat tappet springs (it's not a roller cam) straight plugs, and 1.6 rockers.

Is anyone running these heads? What SA table are you using? I was thinking of using the L98 SA table... but wanted to hear from others what they might have as an SA table.





Current specs...
---------------
1982 Corvette
Bored out TBs (1.95")
20psi / VAFPR
90lb injectors
Renegade intake
Headers, true duals w/crossover H pipe & Magnaflows
Erson .465" IN / .488" EX cam
EBL
TPI fuel pump
Added IAT & breathing exclusively through the fresh air chamber in the hood
76cc iron smog heads
2200rpm stall converter on a later model rebuilt transmission
B&M weights and springs set to give a 5400rpm shift point through each gear
Yukon 3.73 rear end

I ran them on an L98 tpi based motor

It seems to like mild timing. Has a fast burning chamber. Peak torque i had it in the 30-32 deg rnge. 34 at peak hp. Didnt like more

 

Thanks Orr89RocZ.


BTW... here's what it looks like...

 

That is a great looking Vette, Bet it is a ball to drive. How about some under hood pics?

 

Bored out TBs on renegade intake.

If you look carefully, you can see the GM marine pressure regulator modded into usage as a VAFPR.

 

Bored TBs...
Max Bore did the work and added bushings to the shafts as well.

 

Everything hides under the OEM air cleaner. The snorkel is blocked off and it breathes through the fresh air chamber ducting in the hood. It gets plenty of air that way and the air charge stays fairly cool & dense during WOT.

If you look closely, you can see the headers on cyl's. 3 & 5.



Looks like factory- doesn't sound anywhere near close.

 

Since you are running the ebl have you looked at the 3006 i think it’s axcn based.
Anhu or anht might be a better choice for copying the sa tables.

 

I'm not sure the L98 MAP is a good choice. It's actually kinda lazy in terms of max timing (seems like they tired to be careful about detonation due to the high dynamic compression of the TPI manifold, small cam, and the 9.8:1 static compression ratio. Even at 3200 rpm with Power Enrichment SA added on to the main timing table, it's only getting ~25 deg.

Might want to start delving into the LT4 Vette timing map...

Gorgeous Vette BTW...
