This G54B is going into uncharted territory!


Recommended Posts

This Engine is the one that was in my red quest when I sold it. Now it's got a sweet tubular manifold and a bigger turbo. (It's a Precision 6466 and the one I had was a 6262). It's going to be sweet and it's going to break weak parts. haha!

 

The dyno graph at the bottom is from the old (my) setup. Best of luck to James!

I actually don't know. I know that when I made 482 it was 34 psi on a dyno dynamics, and he had it retuned around the same boost and made 547whp on a dynojet. He then turned it up and got that 597, so it would be over 500 on that dyno dynamics, easily. I suspect 35+ psi.

Wow. And thats a bad exhaust manifold!

It's made out of metal, isn't it? lol

hoping my 83 makes that sort of power soon on a t70

 

If your T70 is from ebay, you won't. Sorry.

 

pwm throttle body?

From a ford mustang. It is not very good for this application. Something with a little better design might allow better idle tuning.

 

what cam and valvetrain ? still oem 5spd ?

 

looks hella strong to me

must feel good selling he car to someone who carrys on and kick it up a notch

 

Schneider 292 regrind, AFAIK, still the same trans. 1989 Conquest trans with about 60k miles on it. I am very happy he's modding it.

 

Looks like a p fab? http://www.pfabricat...detail/2724/618

 

Teck, what size injectors used for the 500 + dyno runs. Looking to step my game up my e85 car.

 

Yes, Pfab. It probably still has the Deatschworks High Impedence 1300cc injectors I put in it.

 

Why does his turbo sit so far from the head?

 

Looks like the bar has been set a little higher

 

It's closer than it was before. Custom manifold, you can put the turbo wherever you like. :)

 

btw, this has an O-ringed block, off the shelf 30 over wisecos and stock, shotpeened rods. Unless it has been changed.

A 1.21 correction factor. The air is a little thin up there ;). So uncorrected power would have been about 495Hp? 495 x 1.21 = 598

 

The down side of corrected numbers is they assume the turbo, injectors, head and engine can flow enough air and fuel and the engine hold the extra cylinder pressure to reach the corrected #.

Goin from a dyno dynamics to a dynojet can make that different in power. Definitely in good hands though. What does he use the car for? Any sort of competition or just a highway demoralizer?

 

I meant the good Bad in regards to the exhaust manifold. Is the throttle cable run under the intake?

People who know dyno stuff quickly see the correction factor. I know it skews it high, but 495 is an improvement over 482 which is where I left it. You could use it to gauge somewhat the power output at the crank, I suppose.

 

He does drag race the car, but he launched it back when it was in my old chassis and broke the U joint on the start line on the first run, so I think he just started swapping it after that.

 

And I think the manifold is pretty sweet, so I agree, it's BAD! I turned the elbow for the throttle cable to face downward and ran the cable under the intake. It still has that arrangement in this chassis.
