RWHP how much, how did you get it?

Whats your RWHP and how did you get it. Do's and don'ts?

My girlfriend's (we share this login) 66 is pushing a clam 210 rwhp and 240 rwtq. with a C4 trans.

Ported 66 cast heads
.060 over
Ballanced
crane 222/234 .498"/.527"
Peformer rpm(s)
Holley 600
Headman headers Ceramic coat
2.5 Flowmaster ex kit
Mallory Unilite dist and box
Elect fan. (the dyno sheet show 202 I added 8 for the fan)

Advice: Buy aftermarket heads, even the ported ones cant produce, It flatlines at 5100 rpm. Electric fan does wonders!!

I dont have any numbers on my car, yet. I would think you would be pushing more hp then 210. The c code 289 is rated already at 200 hp at flywheel.

:bloated: Yeah, your telling me, but the tech said it wasn't all that bad. He said we were looking at almost a 30%-35% loss in power through the drivetrain because of the cars age an the AT trans. I found a website of a guy who owned a GT350 (68 I belive) he only dyno'd 148 RWHP with a Man-trans. If I remember right those car made well over 300 horse. I guess new cars have much tighter drive trains.

I am running a supercharger, I too have not dynoed it yet, but I would think it should be close to 390. I will going on the rollers next weekend a long with some GTRs, that should be a blast.

I will hopefully have my nitrous bottle filled, so on boost and 35 shot of N2O I am hopeing for 450. I will post the results.

At your dyno run did you get to mess with your timing, or jetting?

The combo is in my signature. I made 460 rwhp on the dyno before the 42 lb. injectors, power pipe, and additional tuning which netted me 4 mph in the 1/4. So I'd say it was making around 500 rwhp before I pulled it out.

Man, your 60ft time sux:D J/K

You have a really beast there. Let see some picks HP. 460hp, with 36lb?

Just to let you guys know I made 250hp at the wheels, and the car would not go above 4900. I have been working on it ever since last weekend. She feels strong again, but I will be upgrading.

Your web page is very well done. Awesome car I might add.

What Turbos are you going with?

That was 460 w/ 38 lb injectors. Maxing them out a little! :eek: :)
You said you wanted pics, but I assume you found them on my site in my signature. I am in the process of finishing a whole new website for my car in the next couple months.

I am going to most likely do a single turbo. I'm leaning towards a Precision PT-74. Then it should run hard!
