I was looking for a shop to build a custom supercharged engine. Since this site boldly prints foul language, it is obviously not the place for me.
You can say “Kick Ass” on primetime TV, so if you are offended I’m glad you read the website and determined we are not for you.
Best of luck with your custom supercharger motor build.
Too bad your morals are governed by what’s allowed on TV.
Too bad overly sensitive people like you are ruining freedom of expression. What kind of pansy is offended by the word ass?
Toss up between #8 and #18, but I would have to go with tieher #12 or #21 and then sell it to get both of the others with money to burn on more things. I am a fan of tuners HUGE fan. though I can appreciate muscle cars, and would pick a Gallardo, or Bugatti Veyron Super Sport over any of these!!
do yall do work on classic trucks?, i have a 77 f100, do yall do air bag suspension?
Heck Yeah, I have a very similar truck myself. Send me a text with a picture if you want, to 404-486-3730 so we can schedule you in.
Thanks!
I’m up here in Buford, GA. I have a ’12 Toyota Tundra 2WD (5.7 DOHC) non-Flex fuel. I wanted to install Toyota’s supercharger kit but was thinking about porting the heads first, and port matching to the SC. Do you guys work on this motor?
We work on all motors and superchargers are one of our specialties. Feel free to swing by the shop to talk or send a text with what you would like done to 1-888-978-5911 so I can schedule you in. Thanks for your interest.
I have a 95 Mustang standard trans, with a 3.8L motor i wanna make it faster but nothing over 300hp in mods what do you suppose i add on to it but not cost an arm and my left ball sack LOL.
I just added a Drag Race Mustang Photo Gallery – http://extremeperformanceautomotive.com/2012/10/09/mustang-5-0-drag-race-cars/
Maybe this will inspire you to save up for a 5.0. You could pick one up from a wrecked car from a reputable source, and do the swap yourself. Putting money into the 3.8 will just leave you wanting more.
I’m a little worried cause i dont see no mopars on this website. Can i trust you guys with my 440 big block?
Yes Dave, we have worked on lots of Mopars. The pics of the customer cars on this site are actually from just a couple of days in the shop. I should take pictures of all the cars I do, but forget.
