How did you launch your project bolt on car that ran 10.8's @126mph? I am doing a T-5 swap this week and then an 8.8 swap very soon as well and was wondering if you just dump the clutch or did you build boost on a 2 step? Also how hard can you launch a stock T-5 with a decent clutch before the trans fails or the clutch slips, this will be on 275-50-15 mickey drag radials.
What are the details of your project bolt on car? Thanks for the help!

It was launched off of a 2 step at 6k rpm or so (it varied throughout the build). There was an undiscoverd boost leak that caused it to only build a few PSI before launch though which kept the 60' in the 1.52-1.57 second range. Once the boost leak was discovered it would build 20psi at launch but it never made it back to the track before being taken apart for upgrades. It probably would have cut 1.45 or so 60's with that. This was all with a stock 4 cyl T5 out of the junkyard. The launch won't kill a T5, a missed shift with big power will though. When will the clutch slip? I suppose that depends on what clutch it is. There are a lot of different definitions of a "decent" clutch. Odds are you'll be limited to 1.80 or so 60' with those drag radials. They just don't hook all that well with manual trans cars because the initial hit is too hard and there is no sidewall flex to absorb the hit. www.stinger-performance.com/bolton.html is the link to the details on that car. |
