Fully agree with FBII, two years ago at a Rotary Dyno Day stock Gen 1s were getting rwhp in the 70s, the worst 68. I had every possible performance bolt-on from air intake to muffler, plus numerous deletions and a full tune by a rotary racing firm: my best was only 124rwhp.

 

I have a bizillion hp...no not really I have none at the moment but I figure once I get the 12at with massive bridge, and performance headers and exhaust, with lightened flywheel and racing clutch, intercooler, lightened drive shaft, and some others I figure I'll be pushing over 220 probably, just a guess

 

What do you guys think im lookin at?I have an 85 GSL 13 B streetport Holley carb and intake RB header and exhaust, lightweight flywheel and MSD coils

 

What if i added a 9 in camden and only ran like 8 psi(high compression rotors)

 

God I hate you!


My car is completely stock and never dynoed so I have no idea. (Stock rwhp) - (25 years of power loss) = (current horsepower)

Speaking of which, does anyone have the specs for original stock rwhp? I assume the 102 or whatever was flywheel horsepower. Just curious.

 

600 rwhp 20b weeeeeeeeee

 

I'm going to be conservative and say 200hp at the flywheel for my setup, a streetported S4 13B 6 port that supposedly made 150rwhp on stock FI and custom 3" exhaust. The engine is now carbureted with a 600cfm edelbrock and jay-tech intake manifold along with a holley fuel pump. Assuming about a 20% drivetrain loss, my estimated 200fwhp is about 170rwhp. I'm hoping for more, but I'm not holding my breath as the port job seems kinda mild just from feeling around in the ports with the intake mani off, but it seems like a good port job nontheless.

 

I'd estimate 160ish FWHP on my 6-port 13B...

 

Dyno Dynamics 166 rwhp

 

not enough.

 

never is

 

446 rwhp at 14psi

 

140 RWHP. 13b gsl-se engine weber and exhaust. clutch so bad that you could smell it after the dyno runs. It would've been more had it not been slippin. lol..

 

im probably at about 120rwhp with a holley 465cfm carb, RB intake manifold, Monza Headers & catback w/ the rest as 2 inch pipe ( welded myself ) no air pump, and all emissions removed.

 

I have a stock 12a and its no where near enough power, what would be the best way to get it past150hp if possible???

 

496.2rwhp is the most I have made so far.

 

360 rwhp @ 12.5 lbs with nice mods.

 

I am making max 120rwhp, but dang is she fun. ^.^

 

by god, enough to burn out a clutch in an attempt to perform a donut on dry blacktop, in second gear, with a passenger.

 

78hp at the wheels completely stock with an '85 GLS.

 

Hopefully somewhere around 150 rwhp. Full exhaust, some emissions removal, and a little bit of weight reduction.

Sorry, it's early...didn't notice it was the first gen section.

I had an 85 GSL...miss her dearly =[

 

no idea... any takers on a rough estimate?

 

This one made 580HP at the flywheel on an engine dyno.

 

whats is that engine

 

S5 13B turbo
