the 42R is rated up to 900+HP...of course with injectors,COP ignition, etc..all the required goodies....better have a good tuner.

Will send you an attachment of the graph that we made 789 WHP the last time it was dynoed.

The car is a new all purpose drag car that I will run on the 10th November and the setup is follows
1) Magnus custom ROSS 8.5:1 pistons
2) Custom 93 mm stroke crankshaft
3) Oliver rods
4) Stage 5 race ported custom Dan Paramore cylinder head with oversized valves and Supertech valve springs
5) Jun 272 camshafts
6) HKS Kansai intake manifold
7) Nissan Infiniti Q45 90 mm throttle body
8) Garrett bar and plate GT spec 26 x 14 x 5 inch intercooler core
9) Running an MSD 2 step ignition system
10) Autronic SM4 full programmable ecu
Running 50 psi of boost is no issues and the fuel we are running now is VP C16.
Turbo has a 0.98 rear end only thus we doubt if 900 is even possible.
What do you think?

The 4202 didn't make anymore power from 49psi -55psi. The 55psi and 22deg of timing was just ***** out on the dyno
The motor was coming apart soon so we didn't careNow we are going to a 4202 housings with a 45r wheel machined to fit in the next few weeks so im sure we can push a few more ponys and psi

Everything you listed looks great but i would go aluminum rods if this is a drag car. From our testing the steel rods just beat the hell out of the bearings with revving to over 10k and 1000whp. Once we put the Groden Aluminum rods in my bearings where awesome for the first time
What peak oil temps does an engine like that typically see in the entire period from from startup till the run is complete?
TIA

His elapsed speed when he did that time was 220 km/hr and thats 136 mph, ask any of the guys here in evo m, pulling a 9.8 and 9.9 with that trap speed not running on slicks and a proper VHT launch area is very very unlikely.
To back up this fact, on the last round of the drag battle at Sepang our drag evo 3 on its first maiden run making only a limited 33 psi of boost and 9000rpm restricted rev, pulled a 10.3 out on its first ever run at 136 mph to pull the fastest time of the night. It stayed out on the 2nd heats and got a walkover on the quarter and semi finals for the night. ON the final run, the 2nd gear popped out at 7700 rpm thus conceded the run to a 11.5 sec Evo 6 from Singapore.. But no worries, the fact that the car worked well on its first shakedown run made it all for the team...
The purple satria pulled a 10.5 and even boosted up to pull a 10.4 on the next round but never came close to the 10.3 the drag evo 3 did for its power restricted run. Given the exact condition and the power it was running, its not a 9 sec car. The timers were off on the round before that. We know we were still quicker. Its no glory pulling a 9 sec with timers that make the ' wonders ' for you...
The reason for this is that the team is sorting out some technical issues with the motor and power is way way down at 33 psi from the targeted 45 psi that they will run next season.
I have no doubts, a mid 9 pull at over 145 mph will be seen then..

We also have a few mods on the oil pump. also going to a .006 wall clearance on the pistons. I'm sure on a real conservative tune you could get away with a tighter wall clearance but im always pushing to hard

Am running .007 on the wall clearance now with the ROSS
...so far so good except for the mashed rod bearings.. Believe me..over here we are pushing as hard as hard as you... you said 55 psi earlier, and we are going there after we build the new motor...have a problem with headlifting at high boost though..tried all sorts of gasket and even the AMS/TMS L19 studs...didn't changed nothing. You running O rings in yours?
