Took a little time for myself today and got the new Underpressure Power & Performance 76s mounted up. These are their biggest billet wheel turbos and I'm excited to see what they can do. Don't forget they now offer Garret turbos with their kits now as well! PM us for ordering questions.

2011 Callaway Camaro

2011 Callaway Camaro all buttoned up and ready to hurt some feelings. This car runs like a stock car on E85. No cold start issues no bucking it's truly like it came off the showroom floor. Stock tuned numbers on another Dyno were 489/504 STD.

2011 Callaway Camaro. Swapped out the 1 bar MAP for ZR1 3 bar and some Injector Dynamics 1050X to compliment the DSX Tuning flex fuel kit and external pump. Ran into some heavy belt slip from 5500-7k. Made 595/[email protected] on E85 then fell flat to 4.5. Hopefully the 3.4 Griptec pulley will give us the boost we need!

Working on the on board air install for the Jekyll & Hyde Performance twin turbo C6. This will be controlled using our Maxxecu / Maxxtuning AB stand alone ECU. Can't wait to see what this can do with our new Underpressure Power & Performance 76mm turbos. Freshened up motor from Late Model Engines and coupled with the RPM Transmissions TH400/9 inch setup. Last season we lost a close race due to running out spring pressure so this will help us a ton.

Final numbers after the cam swap came out to a stout 808rwhp and 707rwtq @13.1psi. Once the owner gets used to this new power level he plans on a 3.0-2.75 pulley swap for 16-20psi goal.

Update time! Car just got off the dyno! Under further review the cam was installed a tooth off from previous installer. We tossed a custom TSP stage 3 blower cam in there. (Hint we are making 13PSI) Closest one to guess the new number gets a Jekyll & Hyde Performance shirt. If your size is not in stock then $25. Let the guessing begin. How much can you gain just off a properly setup combo?

Details on build: LY6 6.0 truck motor, TSP ported LS3 heads, East Coast Supercharging 2200R, 3.15 pulley, Innovators West, Inc. 10% overdrive, 8 rib DD, Fore Innovations triple pump, Injector Dynamics 1700s, pump E85. Good luck!!

Good parts/Bad install and bad combination = bad Dyno day. Customer purchased vehicle with a gen IV LY6 coupled with what seemed to be a very large cam and some aftermarket heads. He slapped a Novi 2200R blower on it with a triple pump setup along with some nice ID 1700s. Further research showed the cam has an outlandish 19.5 degrees overlap which isn't helping the cause. We decided to see what it would do before ripping into it. First pull on E85 was a puny [email protected] with "18" degrees. We ended up a few pulls later with 38 degrees!!๐Ÿ™„ @WOT and [email protected] ๐Ÿค” not a lick of knock no need to keep wasting time it is obvious cam was installed off or something is off on reluctor. We shall tear it apart as planned and get this thing running the way it should for the customer. Stay tuned for a true Jekyll to Hyde transformation.

Clean as a whistle! Enjoy this beautiful Z06 with only 8k original miles!! Equipped with a built 427, F1C ProCharger, Injector Dynamics ID1300s, RPM Transmissions powerglide. SAE 908/770 STD 945/802 @22psi and 21 degrees. Last it made [email protected] with the 6 speed setup. I say that's a victory going to glide swap. Can't wait to get it on the local track In a few weeks. Meth was not used so we still have that and a 300 shot to throw at it!

Great time tonight before I got eliminated in semi vs a sweet UGR lambo. 2nd fastest in my class tonight [email protected] to his 7.66. Was capped at 22psi due to spring selection. Air control going on car next few weeks so won't have worry about that. Only going to get faster. Better vids will be up once I get emails.
