    Problems w/ new build, need suggestions

    I just finished up my new build, with an 04 Cobra Shortblock, TFS 44cc 2v heads, T-trim, 10% OD dampener and RR intake. It made 598 rwhp on the dyno at 19 psi/6500 rpms. Then the engine started making funny clacking noises. We thought it was a rod knock at first, but then it mysteriously...

    finally a new best, 11.20's @ 125-128

    Got a new best ET and MPH (in different passes). My MPH was all over the place though the day, varying from 124-128 mph in my 6 passes. Not sure if its me or the track timers. Anyway, I'm glad I got a new best ET, and I wonder what's holding my stock shortblock together. I'm #47

    04 Cobra shortblock in a blown 2v GT

    I'm considering getting an 04 Cobra shortblock for future use. Keeping it 2v, and with an S-Trim blower, what other modifications would be necessary? I've read a lot of posts and I'm getting a lot of different information. Here's some of the stuff/concerns I heard: (1) Need new...

    New shifter feels mushy in 2nd and 4th gears

    I just installed a tri-ax shifter on my T45. Shift stops were set correctly, and the plastic bushing was in place. Shifting into 1st and 3rd gears feels very solid and crisp, but 2nd and 4th feels a little mushy. Any idea what could be the problem?

    new times with blower cams

    I previously posted dyno sheets after my blower cams install. There were 2 tunes: race gas & pump gas. Pump tune made 502rwhp/430rwtq. The race tune made 518/465 on a different dyno which reads a litttle low (different tuner) I finally made it to the track, and here's my best ET with the...

    ATF leak thru shifter at high rpms

    While racing at the dragstrip, I was getting an ATF leak from somewhere. The fluid level is/was filled perfectly level with the fill hole. I initially thought the ATF was foaming up and venting out of the vent tube on my T45. But that wasn't it. I took the cover/boot off the shifter and...

    Any tricks to align/shim quadrant position to mate with cable

    Most aftermarket quadrants come with spacers (washers) to set the quadrant position correctly. Well, although I used their spacers, my UPR quadrant must not be aligned well with the hole in firewall, because my stock cable snapped after about 10k miles. It must have been rubbing slightly...

    T-45 oil leak (or burp) during 1/4 mile pass

    If you're running the car hard (like a long burnout followed by a 1/4 mile pass), is it possible that the ATF in the T45 gets so hot that it expands and leaks out somewhere? Does the T45 have vent tubes for such situations? At the end of my pass today, the track official waved me over and...

    Blown 2 valves with 03-04 cobra shortblocks?

    I might be able to get a decent deal on a cobra shortblock for my 99 GT. My near term goal is to make 550+ with my intercooled vortech set-up. I am going to stay 2v, to avoid complications and excessive cost. I heard that the dished pistons in the Cobra shortblock will raise my compression...

    T-45 4th gear lockout & popping out of gear

    Yesterday at the dragstrip, I was getting locked out of 4th gear. On the drive home I found that I couldnt stay in 4th gear, it pops out even under light load. The other gears are fine, including reverse. The T-45 was recently rebuilt (with stock components), and it only has 20 passes and...

    Here's a pretty nice underhood filter for you centri blower guys

    Found a pretty nice underhood filter for my S-Trim, that I thought I’d share with you guys. Since around 2001, I’ve been using a powerpipe with a cone filter in the fenderwell. The outlet pipe from my FMIC passes through the same fenderwell, so things get pretty cramped. Another problem is...

    11.302@126 from a stock bottom end 2v

    Well, I felt this was a little bit like cheating. We had some great 35 degree air with a slight tailwind at Cecil County. The track was fairly empty, making it a lot of fun. Got a new best ET, MPH and 60' time. The gains are not as much as I expected, considering all my new mods, but I'll...

    Race gas w/ timing advance, no gain. Why?

    I have a blown, intercooled 2v GT. My tuner set it up with 3 tunes: (1) a pump gas, safe tune (14 degrees, 420 rwhp) (2) a pump gas/race tune (16 degrees, 440 rwhp) (3) a 103 race gas tune (20 degrees, 470 rwhp) Tune #3 was newly acquired. My plans were to use the safe tune on the...

    Spark Advance

    made my first attempt at datalogging with my Xcal2. I'm getting wierd, erratic readings for "spark advance," and don't know how to interpret them: BTW, this is my "safe tune," which is suppose to have 14 degrees max timing at WOT. This is what the datalog was showing: -In neutral/idling...

    03-04 Cobra tank in a GT -can I do this myself?

    I'm bogging off my launch at the track (fuel sloshing around) unless I have a 1/2 tank or more. So I decided to buy a baffled 03-04 cobra tank, as well as all the evap parts. I never dropped a fuel tank before, or installed/messed around with fuel pumps. I have dual focus pumps in there...

    Review: Mcleod Dual Friction Clutch

    This is the single dual friction disk, not the infamous Mcleod twin disk Has anyone tried this clutch? I bought this clutch, along with an Anderson Hi Rev PP, Ford TOB, and Al flywheel from Promotion. A guy there named Walt seemed very experienced and knowledgeable, and recommended the...

    Bogging off the launch with w/ twin Focus pumps...stock GT tank related?

    After my longtube install, I was at 100% duty cycle on my Cobra pumps and my A/F was leaning out after 5200 rpms. So I switched over to dual focus pumps with a wire mod. Now, after retuning I'm at 80% duty cycle and A/F back to normal (11.5-12:1). However I'm noticing a new problem: When I...

    MGW shifter

    I just put this thing on. My initial impressions were very positive. Very solid, precise shifts. No noise. It feels like I have a new transmission. However, when it comes to shifting fast, I think its slowing me down. With the stock shifter, each shift was over in one quick throw. But...

    0-110 mph acceleration in a blown 2v

    I was originally trying to capture a stutter during high-rpm shifting to show my tuner. It didn't happen this time, but made for an amusing video. Sorry for the beep-beep, but my camera hand was resting on the steering wheel for steadiness, and the beeps happened when I shifted into 2nd...

    No gain with LTs on a blown 2v -suggestions?

    Just thought I'd share this information, and see if others had similar experiences. With a Vortech V1 S-Trim, and a 3.05" Reichard Pulley, I was reaching 10-12 psi at ~6200 rpms. This was with the stock manifolds and Bassani X-pipe with cats. Power level was ~ 440 rw-ish. I put in BBK...
