Anyone use one? I want more insurance than the factory crank but im to cheap for billet. I read that it significantly enhances the strength of the crank but its hard to know how much.

Since the introduction of the 2.65 rotorpack it seems 1100-1200 rwhp builds are becoming much more common. Has anybody built a motor specifically for a KB3.6 WITH 10.0+ compression, ported heads and intake and all the boost? Im curious on the specifics of your setup(compression, boost, power and...

I am putting together the parts to do my first modular build in my 07 gt500. I am intending to have a local machine shop who does a lot of modular stuff do all the machine work i need on my original 20k mile iorn block. My question is to those who have built their iorn block, what bore size were...

For the people that have broken an output shaft on their 6060..... what method did you use to fix it? I assume if you made the power or traction to break it you could use an upgrade to something stronger. My buddy told me to look into something cryo-treated from liberty transmissions. I didnt...

Has anyone had a alternator voltage regulator go out on them at all? My 200 amp PA performance alternator started giving me reading from 12-16.2 volts according to my aeroforce gauge. I think I need to take this thing off and send it to PA.... Was curious if anything similar has happened to...

If my car is sitting at idle in neutral and I try to put the shifter in 3rd and 4th gear without depressing the clutch it grinds. Does this mean my syncronizers are bad? I just had my transmission rebuilt with carbon syncros for every gear and bronze shift pads.... the same gears grind when I...

I recentley lost the 2nd gear syncronizer in my factory 17,000 mile 2007 t6060.... through a little bit of research I came across this new "hybrid" syncro/blocker ring kit from tremec wich some say will fix the dreaded t6060 grind issue that gt500's are prone to. Has anyone replaced their...

What is the easiest way to get one of theese pulleys off the car? It doesn't seem like the 3 jaw puller I used to pull the stock pulley will work here. Just curious what techniques or tools people have used. I didn't see any recommended removal procedures in the install instructions. Thanks !

So I recently had my 2007 dyno tuned on 91 octane and e85. Car has a lethal return fuel system and id1300 injectors so I can run e85. Made great power on the dyno.... Made 775rwhp on 91 octane and much more on e85. The car ran great on the way home from the dyno.... I had to stop multiple time...

So I have a dyno appointment coming up soon to tune my 07 on E85. Currently the car is tuned on pump gas. I have ran e85 before but was running email tunes so it was easy to run the car empty and load the E85 tune at the gas station as I filled up. What is the correct method of switching fuels...

I've had the division x dual pump fuel system on my car for awhile wich comes with Lethal Performance wiring harness kit that is wired in a way that the fuel pumps run 24/7 when the key is on. Since the day I installed the kit I have had a check engine light wich I have always assumed is caused...

Loaded a new tune the other day and started the car and the traction control light was already on. The dash said check traction control.... I didn't think much of it. Took the car out to try and do a WOT log and the car had a soft pedal and seemed to have no ABS. I'm curious where you guys would...

For those that are running the whipple elliptical mono blade throttle body or have knowledge of what is needed to make it function properly..... I know it is not easy to tune for drivability but is there any other things necessary like adjusting tps voltage and such? Only aftermarket throttle...

Rrecently I nstalled a new clutch in my car when the stock unit gave up. I replaced it with the McLeod RXT and it feels great. Ever since the car has been back up and running it is down on power for sure.... it is still fast but lacks much of the performance down low and up top as well. the car...

Finally drove through my stock 07 clutch last weekend and due to the cost of the clutches for theese cars I'm contemplating doing the RXT install myself. Can the tranny be pulled with the JBA longtubes installed? For those that have done it.... how was the available room and the whole install...

Is anybody using an aftermarket swaybar with their FAYS 2 watts link? I know some don't clear the main support so I'm curious if there are any bars known to work. I Also have the sway bar relocation brackets if that makes a difference. Thanks guys!!

Hello! my car has 750+ rwhp and a 4.10 gear... long story short.. I rarely go to the strip and find myself more into roll racing recently. as of now i have been using tire height to make up for the gearing when I feel like roll racing but i think i have the tallest possible tire on the...

Ive been working on getting the car running right with the 1400rwhp division x fuel system from you guys and I recently noticed a small puddle of fuel under the car after filling up with gas. The fuel hat seems to be leaking fuel from the electrical connector. I tried re-adjusting the snap ring...

I recently installed a return fuel system in my 07 gt500 so i could run E85. After I got the car running i was checking parameters on my Aeroforce gauge and the FPDC would hover around 29-30% at idle. I assume this means that the car is usnig 60% pump capacity at idle which seemed way high for...

Ive been using the one step colder than stock Motorcraft SP471 gapped at .029" on my 20+psi TVS setup and it has ran great on pump gas... but i have now switched the car to E85 and was curiouos what plugs and gaps others run in their setups. Should i go back to the NGK TR6?? Thanks

Has Anyone installed the Division X 1400rwhp fuel system that Lethal Performance sells(specifically on a 07-09)? If so, how was the install? I'm in the process of trying to install it on my 07 shelby and am having a horrible time routing the pre cut PTFE lines. Anyone have some insight on the...

A buddy of mine running a 2.9 whipple making 690 ish rwhp on e85 on the stock 08 longblock just blew a hole in the side of his block. Im not blaming the tuner as we do not know why it blew.... but it left the tuners shop with a 6800 rpm rev limiter. I was always under the impression that the...

Got these mounted a few days ago finally had the chance to raise the rear of the car a bit to help them fit better without the chance of rubbing. I really like the look of them on the car and they work pretty well considering the car has 4.10's and ~750 rwhp. They are supposed to be 29.9" tall...
