Eric, do you have 1 or 2 clamps on the Accusump? One thing to watch for with Accusumps is to not put to much pressure on the clamp/s as it squeezes the tube and slows the internal pistons travel/responsiveness. Last one I used I clamped it at either end so the clamps were bearing mainly on the tube end fittings.

Great to see that you have the beast ready to rumble Eric and look forward to hearing what sort of numbers it punches out. Also looking forward to hearing what you car weighs now with the LS motor.

Good luck, Kel.

Thanks Kel, I have 2 clamps, one at each end just as you stated.

Hopefully all goes well, I'm a bit nervous!!!

So the initial report is good/bad.

The good.... they said the car is running great! Still have some tuning to do, they had to order a couple new jets for it.

The bad... the power is down a little than i expected @ 369whp, not sure on torque yet, the top end power seems to be hurt by the crappy short tube headers, and would have been better to use a single plane intake manifold...

but its a lot better than it was and i have some areas to improve on, but i'll take reliable over fast!

[NZGTRA17]

Good to hear the car ran well Eric. At what rpm was the 369 peak power? What sort of dyno was it run on (i.e. Dynojet or other)?

[Dawgfan]

Eric, how much beefing up did you have to do to the front end for the extra weight and torgue?

I have no idea, I have not seen any of the graphs, I dropped the car off and they are tuning it. I will pick it up tomorrow and i'll have more to report then....

I dont even know what kind of dyno it is, they are a reputable chevy tuner here though.

The process was very complex...

Step 1 remove old engine

Step 2, insert new engine

Step 3 Save 185lbs and add @100hp



The ls1 is lighter and cheaper to add power and should be as, or more reliable. no reinforcing is necessary, my car already has all the GTS chassis bracing plus some!

[Dawgfan]

I know that I have been told that my WC car will have to have a cross brace and maybe more chassis work to handle the torgue???

[eric1h]

SOme of the WC cars have the GTS bracing, some have some, and i guess some have none. hard to say.... but the GTS is 450hp stock so if you have the same bracing as a GTS(search for the thread here) then it should not need any extra. Anythig more than 450-500 and you will have to start worrying about chassis flex

[Cobra4B]

Our GTRA has all the GTS bracing... odd that the WC doesn't.
