Good weather today in St. Louis. Put the angry smurf up on the rollers: 660 hp and 665 ft-lbs! Pretty happy! Thinking cams next as i need to drop pressure; currently about 20 psi, so not alot of room to work with.

I have some brand new take off ‘13-14 cams and springs.
Great numbers and torque.

Gene did I read that correctly? Whipple 3.8?
First one I’ve seen or heard of.
Do you have a Dyno graph with RPM not speed or the power and torque on the same scale?
Awesome numbers!

I only have this last dyno sheet. Out of injector. Will pick up lots when I can rev it higher. This was 7000rpm. This blower comes on strong up top. I just finished dialing in ID1700s. Will have plenty of fuel to rev it next time. 15 pct/3.5 pulley and the auto eats lots of hp compared to a stick.

In Ellisville/Ballwin area. I go out to Wentzville a bit, friends own Friendship brewery out there that I like to visit.
Now that cars and coffee back, may have to do a cruise to one of those. Also trying to plan a car show at my brewery late summer/early fall.

Finally have my 2011 GT500 dyno tune this Thursday morning. Should have been done last year but my McLeod RXT 1000 clutch slip so have to install a new clutch this year. Mods are listed below:

- 100% stock 2011 GT500 long block with stock camshaft.

- KB 3.6 LC with custom designed and 3D printed inlet manifold.

- KB dual 75mm throttle body with machine ported inlet for improving air flow.

- Custom designed and 3D printed 136mm CAI. Still hasn't try my custom design 148mm CAI (AKA 148 mm Gatling Gun)

- KB Bigun intercooler with modified 1" inlet and outlet water tubes / manifold by J2Fab. Custom designed and 3D printed aluminum inlet & outlet I/C water tubes

- Custom machined lower intake manifold for Bigun intercooler and remove rear block off section.

- Old style (the Original) VMP dual pass HE with modified 1" inlet and outlet - not the later VMP triple pass design.

- American Racing 1-7/8" LT header with off road H pipe and Corsa sport muffler.

- ID 1000cc injector with VMP pump booster.

- X-clutch Triple disc clutch and flywheel assembly (15 lbs. lighter than stock clutch flywheel assembly) - Thanks James for letting me use your place to install this new clutch. I had the McLeod RXT Twin Disc before, but it slips pretty bad.

- 13/14 carbon Fiber driveshaft - I think the stock CF driveshaft is toasted after this dyno tune session as I can feel the vibration at highway speed while heading home.

- 93 octane pump gas with Boostane - Boost starts at 17psi @ 3000 RPM and reach 20psi @ 5500 RPM. Then peak @ 22psi at the end of the pull at 6600 RPM.

- 19 to 20 degree timing - I can put 1-2 more degree to squeeze out more.

Final dyno results:
* 840 RWHP SAE corrected
* 700 RWTQ SAE corrected

Torque seems kind of little low when compare to the newer 2650 TVS S/C. My pervious VMP Gen II 2.3 TVS (NOT the Gen II-R) made the same 700 RWHP / 700 RWTQ.

The KB Bigun I/C with the 1" I/C mod by J2Fab couple with my custom 3D printed 1" I/C water tubes works very well. The temperature different between IAT vs. IAT-2 is only 11 *F at the end of the pull @ 6600 RPM.

The fuel pressure stays strong and steady during the pulls.

If this is a 13/14 GT500 the final result would be at least 870 RWHP due to 0.4 more displacement, 9 to 1 higher compression ratio (07 to 12 has 8.4 to 1 compression ratio), and 1mm more lift camshaft from the Ford GT.

Maybe next winter (not this coming one) install a set of L&M NSR camshaft.
