the highest RWHP on a LS1????
i never see any z28 or t/a with over 1000 HP
Ronnie Duke probably made at least that much (387C5R, F1R, N2O) when he went 8.5
Also don't forget the Skylines are typically fully backed by the manufacturer, so they have unlimited resources. There are only a handful of Supra's over 1200RWHP (I can really only think of one or two and they are pretty much all out race cars). I don't know of any street Supras that are over 1200RWHP.

Our TSI emu will not longer be required due to the new maf.
FYI Bone stock 03 cobra 160#injectors and a fuel pump with a t-76 or t-88 ran 8.5@155mph
it made over 1000rwhp FYI Bone stock 03 cobra 160#injectors and a fuel pump with a t-76 or t-88 ran 8.5@155mph
it made over 1000rwhpKeep reading stuff on the internet, that'll learn ya...
The Cobra motor is quite the beast, too bad it ONLY makes 390HP (rated) from the factory with the blower (still down on power to the LS6) and gets shitty mileage to boot... Hmmm Maybe the car wouldn't be so damn heavy if they'd just bow down and put an LS1/6 in it?
1200 FLYWHEEL hp for 1krpm is not so inpressive and won't run inmpressive.
the 2jz motored solara race cars, need 100+rwhp just to run what n/a huge ci motors do, even though the solaras surely weigh less.
Nevertheless, there were some excellant threads at this site last year debating the strenghts and weaknesses of LS1 versus LT1 versus SBC versus CR5 motors. Maybe PSJ could resurrect that thread and we could just add on to it?
As I recall, one of the most controversial points was that LS1 motors have not proven to make the power of sbc motors; 15 sbc head bolts versus 10 LS1 bolts was a point of debate.
Fuel Injection tuning and development is still in its infancy, and most of the LS1 motors that are out there are still basically running "upgraded" stock parts. There are very few race-developed parts available for the LS1... whereas the big HP small blocks are running things like Tunnel Rams, HUUUUUGE roots-blowers, Cylinder heads developed for nothing but all0out racing (like Winston Cup SB2 heads or even the myriad of 220+ CC intake runner aftermarket pieces.)
The fact that the LS1 is already as capable as it is... shows just how good of an engine it is. I think that once the aftermarket for the LS1 matures... and the racing teams start developing parts for them, we will easily see results similar to those of the SBC if it doesn't surpass them significantly.
I'll have more definate info for you on Friday after the guys get done in TX at the dyno day (can't let any cats out of the bag yet).
I too am using the LQ4 block with 9/16" ARP head studs, drilled and tapped deep into the block, plus head o-rings and block receiver grooves. And, after much pain and suffering, I think it will now hold together under 1000 hp.
But tell us about your setup? Blown, TT, NOS, . . .
