Great pictures - I love seeing these engines apart.

RSRanger

Not saying much yet
Just preliminarily how's 402 ft/lb rear wheel torque sound
Best is that it's all there at 3000 rpm and sustains through 7000 rpm (only went to 7K on initial dyno).
We ain't finished yet.

Godspeed, Ranger......Subcribed....

GTgears

Sounds like my old Subaru motor. It only made half that power, but it was a flat line making 200ft/lb of torque from 3200rpm to 6000rpm. Driving an engine like that is just dreamy.

this has got to be the BEST thread.

So.....what is the latest on this build? Any track time yet? This thread got quiet really quiet.

RSRanger

Trust me the wait is k!lling me.
Things are happening but the devil's in the final details. The tuning has been on going creating several maps.
The numbers so far are encouraging
It's happening.

Thanks Ranger...hoping the best...hope to be on track with you. Im really great at point bye's...Lol

RSRanger

Thanks and that's funny but I'm an old man. The older I get the faster I was,
15-20 yrs ago I was fearless (win or bring back the steering wheel), now I worry about my boys, school/college, wife, home, investments, economy, oh yes a job.
We turn into a POS, so it seems.

Yep I know the feeling...I use to be fearless in everything...hence riding a motorcycle and losing my entire left leg..LOL But I wish I had video of how I use to drive an old Ford truck and my old Camaro and Vette around back in the early 80's...Tokyo Drift had nothing on me! LOL
I can't afford to wreck, I can't afford to take any big hits to my body and I can't afford to lose anymore body parts....oh and I hate hospitals.

RSRanger

Here you go folks. Here's 2 of the RS's final runs, overlayed on the same graph, corrected to STD.

holy ****!!!!!!!!!!!

is that WHP? or FWHP?

RSRanger

All sweet naturally aspirated rwhp and rwtq.
Actually still not totally done. There are some details pending.

Just amazing, great job to RSRanger and Champion.

Has champion run a rs 4.0 on the same dyno to compare? Im sure yours makes more power!

I have seen a average of 8-10% drivetrain loss with GT3 911's, so my conservative FWHP for those numbers are 525-535 HP!!
