    Mac L/T & Prochamber install

    The sound is deep, no trumpeting, no raspy poping. At full throttle sounds like a 5.0 with flowmasters and a O/R H pipe. Sorry, I have no way of adding a sound clip. I know, LAME!

    Mac L/T & Prochamber install

    I installed Mac long tubes and the O/R Prochamber this weekend. I was first impressed with the fit and finish. The install took 3 hours (but I have a hoist) and there are no clearance, rubbing or rattling issues. I did not do a before and after dyno pull the same day, I should have. The last...

    Help with Long Tube Header Install

    I just installed Mac L/T headers and the O/R Prochamber this weekend. The install was easier than it would seem. Start to finish was 3 hours. . . . I have a hoist though. Motor mount and starter removal is a breeze. Getting the stock manifolds and studs out is the biggest pain. Once you lift the...

    sick of hurst!

    I must be old because I think the stock shifter is pretty darn good. I power shift my 08 everytime I go to the track. I have only missed second one time and never missed third. But, I am used to drag racing with Muncie's and A833 Hemi 4 speeds. Anything is an improvement over those. I was going...

    2008 BULLITT 1/4 MILE TIMES

    I am sure it's possible to get a stock Bullitt in the 13.20's. I ran my 08 GT a few weekends ago with the stock tires, tune and airbox. It went 13.12 at 106 MPH, the only mod was the 4.10 gears. the density altitude was 350' and the air was 58 degrees outside. Like Brian said, it's all in the...

    1/4 mile times

    What altitude is your track at? If the density altitude was high, 13.71 at 103 MPH might be a really good number. I saw a 08 Bullit run low 14's at 99 MPH all night long at a density altitude of 350 feet this month! He told me his 60' times were in the 2.60's and he was shifting at 4,500 RPM's...

    1/4 mile and gears

    Even though you have to shift into 4th with 4.10 gears in the 1/4, my car is still faster with them than with the stock 3.55 gears. I have a bet with a friend that I can get my 08 into the 12's with the stock tune, airbox and the stock tires. Other than the 4.10's and road race springs my car...

    saw a ZR1 on the road today...

    It's rated at 375 HP. I had it on a dyno a few years ago and it made 412 RWHP.

    saw a ZR1 on the road today...

    I see one everyday. . .that's because I own one. Truth be told, Mine is a 1990 it has 28,000 miles on it. It would not come close in keeping up with a new one, but it still runs 12.40's @ 117. I drove a new one a couple of weeks ago, I thought about trading my GT in on it. I had all the...

    Autocross

    Make sure the rules allow you make the modifications you want to make. Otherwise you might get bumped into a class you will not be competitive in. I run H&R race springs with Koni's. I have an extra set of wheels and run Toyo 888's in the dry and Toyo T1R's in the wet. I have the Ford strut...

    The best way to make your stock 5.0 fast?

    I agree with everything you said, I was taking in to account his car was in good running condition and what is possible in good air with a good car and driver. I drag raced my 90 last year and it ran a 13.70's at 99 MPH on street tires. It had just over 200,000 mile on it at that time...

    Fake Gas Cap Removal ??

    I used a heat gun to pre heat the cap and then it just pulled off. You will need some 3M adhesive remover to help remove the glue after the cap is off.

    The best way to make your stock 5.0 fast?

    I bought a 90 LX 5spd without A/C new in 1991. With 3.73's, O/R H pipe, Flowmasters, 15x3.5 and 15X8 weld wheels, 26X10 slicks, shorty equal length headers, underdrive pulleys, air silencer removed, front sway bar removed it ran 13.40's @ 99 MPH with a 1.68 60'. I ran a NOS nitrous kit on it...

    What size tires?

    I bought a 1990 LX 5sp new, I ran 26X10 M/T slicks on it for 4 years on the stock 10 holes. The car would 60' in the mid to high 1.60's. I never broke anything on the car. The engine was stock except for headers, Flowmasters, off road H pipe, underdrive pulleys and I had 3.73 gears. It ran...

    anyone else with procharger problems??!!

    It's going to feel so slow compared to the old setup! You should run it at PR next Wednesday night just to see how much slower it is. I will bet you $5.00 I can beat you now.

    Brian, do you have the stock parts and tune so you could at least drive your car?

    4:10 guys????

    I used the factory weight oil in mine. I lost about 2 MPG on the freeway but my mileage increased around town. I lost roughly 1 MPG city and highway combined. To me, the 4.10's are worth the loss in mileage.
