That dyno chart is flawless. Nice job yeah as you can see your toque is around 180hp from 3k to 4krpm which saves your rods plus he didnt let it all at once. Great AFR's too. Why isnt he on the boards here???

 

Kevin's on Rennlist. He's a real good dude. Doesn't try to squeeze out the last couple of Hp for the sake of safety. He's very conservative.

 

Yeah i was going to use him but never got around to use him 3 years ago. Tpny at epl got this tune dead on for these new turbos. How much boost were u running?

 

Same turbos after we put in rods. Again 91 octane. Kevin retuned it and started bringing on hp/tq earlier shifting the power curve quite a bit to the left. Smooting is 4 instead of 5 so the graph is a little more jagged. Ignore the AFRs as the tailpipe probe was not inserted fully into the exhaust. Logs showed it right at 12.0 across under load.

Boost is 1.25 bar running 100 cell HJS Motorsport cats and stock MAF which is scaled about 10% over it's limit. Power is essentially capped by the MAF.

 

Wow at 91octane it seems to run great at 18+ psi

I have went at 683awhp at 19.3psi but lowered it after the dyno. Back to 18psi. Im still on stock rods.

 

Are you guys planning on going to Hershey?


I would be up for this but I'm headed to Colorado for some snowboarding!

 

k16 billet turbo rocks! I am lucky to own it.

Meaning how much torque occurs in a 1k rpm range to much torque will bend a rod. As shown from the OP he will bend his rods with that tune.


Pdwrhound will not bend a rod because his torque is not instant and its lower in a 1k rpm span.

 

You've got me worried about bending rods now.
On my stock engine I have K16 billets, 60# injectors, 1.25 bar Markski tune, 93 octane, IPD plenum, upgraded intercoolers, etc. The tune has been tweaked to my car with multiple durametric data logs. I only take my 996T to the track 3 or 4 days a year max.
Now I just modulate the throttle and do not floor it until I am about 3500 rpm.
Should I be more conservative and wait for WOT until 4000 rpm?
Thanks

 

No you dont need to worry markski knows what he is doing.


If you look at the first post at tge OP dyno chart this is what you do not want to see on a k16g. 650hp torque. The lines are dipping and not steady which means knock is happening and timing pulled. Installing a 5bar and not retuning and running 1.3bar on stock injectors. Also the instant torque is way to high.


I do wait to floor mine around 4k rpm in a higher gear it puts less stress on the rods.

 

Thanks for the quick reply.

 

Your welcome also you might be thinking pwdrhound is also high in torque but he has upgraded rods.
