Are you talking turbo kit alone, or the motor, trans, converter, rear end, drive shaft, fuel system, and tune all together to pretty much replicate it?

you mean the stock 10 bolt, torsen carrier,stock trans & fuel system wont work to make 1142 hp? LOL, LMFAO

yeah what did i cost in all aftermarket parts? 20k?

Oh and we can also include a motor that will hold the power instead of one on borrowed time, but still 4 bolt heads, probably $30k with the suspension wheels and tires/safety stuff that will be needed + buying a car. Kind of a rough number.

Me and a friend of mine are kinda doing the same thing. We got a junkyard ls1 and a 4788 turbo to go into a 1994 firebird we picked up for 600 bucks. The ls1 is just for now until we can get a purpose built motor for the car. This give us alot of incentive for the backyard builders kinda guys.

whos turbo kit are you using ?

The numbers are very impressive. I'll be more impressed if you can get it to last as is.

Sorry, I just giving you crap and it was an outrageous number that will never see the street or track.

Ya we made 900hp with and ALL STOCK LS1 and a T76 turbo and it lasted 1 run. Put a hole in #7 piston.

So the timing was only 10.5*?

Wrong direction, 20 plus the 9.5 degrees.

Wait, that's almost 40* of timing!

very sweet, congrats! who built the motor thats in it now?

You guys make me want to convert my 370 nitrous built motor to a turbo setup. On the juice I'm barely making 700hp. I'm jealous......

MaxxMitchell

lol no more like 29.5 unless I missed that family guy episode.

Basic physics. If you double the pressure/density of the charge you double the output, unless of course you see a backpressure problem and reversion issue.

You can pretty much plot a turbo car power output vs the power output at atmospheric pressure, with degrading gains as you go as a result of chokes in the system such as backpressure, compressor efficiency losses as you go off the map and the discharge temperatures rise exponentially as you near the edge of compressor efficiency, and of course driveline losses with auto cars as you input more torque the converter slippage goes up

Holy chit that IS a ton. It would have to be roughly half that to survive based on my experience. I run <20 with less power

With e85 it'll take the timing better than you think, but yes obviously that much timing is just for the dyno number and it wouldn't hold on the street/track. I bet it won't push any coolant at 20 degrees though.

mine on E85 doesnt pick up appreciably above 18, not to the point id risk it. I always like less timing leaner than bunch of timing and try and cover it with fuel

On my rx7 we ran up to 26 degrees to see what it would gain, but vs 20 it only made 10rwhp more so left it turned down at 20.

It was still making power with the added timing(and not just a few hp either) that is why he ran so much.
