You do realize at your boost levels and stock weight I would still be much faster.....right? 16-18 lb's on a stock ls6 would make around 800whp.....maybe more.

I was just saying that my car is pretty much at stock weight, nothing lightened or taken out of it.

Heater even though its expensive you should **** can that IRS(though you can get decent money for it). Though they do look nastier with IRS on the rear with exhaust..

16-18# makes 800+rw on a stock ls6?

Wtf are you smoking?

Forged 347s with a cam and afrs don't hit it maxing out the blower.

My buddies 370 only put down 650ish.

It has as gooda chance taking it as your engine. Look around, 5.3's do it all the time. Stock bottom ls6 recently went 9.1.

You went a different route is all. You basically can't get a bolt-on n/a ford where I am until the new 5.0's. Besides how I did things was not just for drag racing.....I did what I did for overall performance.

maxing out what blower??? Blower would and should be sized correctly for the engine.

Just because a stock 5.3 Will do it doesn't mean a stock ls1/6 Will.

The 5.3 Will handle more than any other stock short.

Nobody has made that much with a blower anyway, they are all turbo cars with 5.3/6.0.

The impeller speed Will be maxed out, it has nothing to do with matching it to the motor. It Will only make so much boost and so much power. Which happens to be 17-18# and nowhere near 800rw.

You are thinking of matching a turbo to the engine size.

The difference between a 5.3 and ls6 bottom???? Coated pistons in a ls6. The ls6 bottom record was done with a centri blower. I don't think it's a 5.3 is stronger issue. It's a 5.3 is cheaper issue. Most use a ls6 cam.

The ls6 will flow more air than a termi.....hence it will make more power.

Blower speeds should be run at a optimal rate for it to be a fair comparison. From what I have seen it would not take as much boost for the ls engine to eclipse a 4.6 mod motor.

My estimate was a pure bullshit guess. But fore sure it will make more at equal boost levels.

I have seen mild Termis break that IRS on drag radial(which is why guys use slick with them). Axles were only used in that car so they are not cheap. Solid saves weight and doesn't hop.

Of course.. There is no replacement for displacement.

Im on phone so not breaking it down a quick search Will lead you.. The 5.3 Will handle more boost that any other stock short block.

I understand.....but ride, drive and handling is better with the irs. All that is far more important to me vs dragstrip times. Besides I bet the irs has more traction on the street.

i wish they woulda did a 4th gen with irs.

Irs doesn't have more traction period. Only thing it is better at is handling. SRA demolishes it straight line.

Uneven road surfaces and I will take irs all day long. Irs will make more traction like it or not. Remember I do not consider drag racing a end all be all......and even so there are some pretty impressive drag racing irs **** out there these days.

i will never dyno the turbo without boost, but it is likely in the 280-290rwhp range. not much to brag about.
There have been some guys with cams only c headed cars making damn good power north of 370. No **** everybody knows the c headed cars are going to be faster mod for mod. The argument was over the power they can make and the ets b headed cobras could run with boltons
