Prolly the overall height. I love the Whipple look and performance but you have to remove the rain deflector with it. A small price to pay though. (after you pay the big one!)

If and when I ever pull this trigger, I’m leaning Maggie but man, gonna be a tough decision.

The Heartbeat is one of the most efficient superchargers available on the market. it has 850 RWHP capability.

We sell plug and play supercharger systems with all necessary supporting mods.

For example Heartbeat, LT headers, Optional pulley Rotofab, ZL-1 pump and control module JRE tune 560 RWHP on 93 octane all day long.

Feel Free to give me a call and I will put an estimate together for you. 203-753-7223

October Texas Mile update: If anyone is still interested. I still missed 5th on every pass, but I made a little improvement. 132.4 @ the 1/4. 163.8 @ the 1/2 and 186.6 @ 1 mile. Going to make a few changes and see what happens in March.

Hope everyone has a happy and safe Thanksgiving

Cool. Can’t wait to see the results. Who is doing your build? Are you planning on running spray to smash that record?

I fitted a Heartbeat kit to my 2013 LS3 a year ago. No regrets, getting used to the power now; I also had GM CNC heads fitted to help the breathing. Already had long tubes, HF cats and CAI. Motor is making 568 rwhp at 6000 rpm. A real hoot to drive, she'll light 'em up at 50 mph no probs at all. my kit only came with one pulley; are there others available for a Maggie Heartbeat? Now I'm used to the power I have been thinking about a bit more but don't want a lopey /choppy cam - I like the fact that the car is still very streetable and we use it for european touring so I like it civillised!

You definitely have room to turn it up by adding fuel system injectors, cam and pulley along with a new JRE tune. we can make 650 RWHP very easy and still retain all the comforts and driveability.

Now's the time Black Friday sales are upon us.

Ted.
