I did a few more runs for this weekend when I supposed to go to the strip. I also fixed the hole that is in the a/f chart so I did one 19 psi run and two 26 psi runs.

badass, nice numbers. let us know your 1/4 times when you run.

 

[Silver88Turbo]

Awesome!! What turbo are you running? Ah hell.....might as well list all your mods cause you know ppl are gonna ask.

What really sucks is you spool at 4.5k and you only have till 6.5 before you redline... But that is some SERIOUS power!

 

[stokeless]

what is your setup; nice number

The spool got alot better when I fixed the hole in the a/f chart, but I ran once after that on a different graph. The car was loading up until then but the numbers for the last chart were 500 rwhp/465 rwtq @ 19 psi with the a/f's at 11.5 across the board.

damn sean! Impressive as usual!

Huge congrats!!!

what internals again?

 

[dbsupra]

congrats sean!

500rw at 19psi is sweet!
even [email protected] psi there is still plenty of room there. next time you dyno i want to get a call about 30psi and 600rw

nice job man.

[toyota_supra_1988]

sweet numbers

 

[X-man]

Thanks and it's stock balanced and blueprinted internals with an HKS 1.2 MHG and ARP bolts torqued to 85 ft/lbs.

 

[toysup87]

hoollyyy hell, those are some serious numbers.. awesome job man, post the 1/4 time when you run it

 

[TaSe]

Nice What does blueprinted internals help? what does that do exactly?

 

[Robbman]

You owe me some Rogaine® after that blow-off valve let off on that run

 

[bigrick]

very nice numbers, grats

I'm wondering this as well, I hear it from time to time but never knew what it meant...

 

[ZaZZn]

whats ur mod list dude?

 

[Krister]

Why is there such a small gain in power when going from 19psi to 26psi? 500rwhp vs 557rwhp ???

 

[TaSe]

no 1 have the answer?

 

[Po' Kid]

Blueprinted (and balanced) I believe means precicely machined so when they spin they are completely even and dont have more weight on one side of the axis than another, which would make them want to wabble. All it does is pretty much make em more reliable at higher RPMs and less likely to distort and spin bearings and such at higher power levels. If there is more please feel free to chime in.

I might be getting to a point where the a/r on the turbine is causing too much back pressure. I talked with SP when I bought the turbo and they said in this configuration that it should do around 680 to 700 hp at the flywheel so I figure if I can get 600 rwhp or close at 30 psi I'll be happy and then I might change a/r's and go to a .81.

When I built the engine all the pistons, rods, combustion chambers and such were brought to the same weight as each other. ie all the pistons weighed the same, all the rods weighed the same and so on.
