Default My K27 HFS results

I know we all like dynoplots to critique
I had my car finally get to the Dyno today @ Auto Edge.
Bob has a really neat programable system for the CIS that works great AFR's are no problem
Here is the sheet.

Tell us about the mods made to give you 11.5/1 AFR at max rpm. Usually CIS doesn't fuel the higher engine speeds well, even when using the stock K27.

It uses a unit developed by auto edge and a fuel injection engineer, I am not sure of all the ins and outs but it is a laptop programable unit with a proper fuel map that controls the pressure across the CIS I do know that supporting 600HP with this setup and CIS should be possible as we were able to get A/F into the 9's with only 75% duty all the way to redline.
Give Bob a call.

Jon, great info. Will do.
The power figures: flywheel hp or rear wheel hp? Also, what boost were you running?
Thanks.

Jon, wow, you've done a lot of stuff there!
Is the Whipflash system proprietary? Google didn't find any hits.
Besides the HFS, l/w flywheel and headers, were any other mods done to the powertrain?
Lastly, please compare the l/w flywheel to the dual mass one for starting and acceleration.
Thanks.

the whipflash is built by the shop so there wont be much info out there.

I re-geared the tranny with a close ratio 2-5 set so it will stay on boost/cam during the shifts

Nice.
How do you like the l/w flywheel? Please compare it to the stock dual mass flywheel.

I have had the L/W flywheel and clutch for about 5 years...it's a lighter feel but no noise issues that are often reported and the engine spools so much quicker and is more responsive to throttle input.

Be careful Paul, you are conversing with a guy who drives our track backwards

I dont have the bill at home, but I remember it was $1000,00 for the unit installed, tuned including dyno time. I will check Monday.
the flywheel makes a Positive difference, revs quicker I have no idle issues ext .
