This was my first run today I ran immediately after I got to the track after driving 50miles to get there. This was the first time with drag radials at the track launced at 3.5k and bogged off the line. Second run tried 4.5k and blew my passenger side axel apart .

 

Yea man blew my drivers side last Sunday on the first run.. Launched at 4 k....

Those tires are hell on axles, unless u slip the clutch off the line.....

Good numbers!

 

yea i was trying to get my 60ft down guess I'll be waiting till next year now.. lol

 

About 450whp?

Thats judging by the trap, the ET obviously has room to improve at that trap.

Good show first time out!

 

Well I dynoed at 485 on dynostys dyno but I also had just driven about 50 miles and literally went straight to the water boxes and ran..... Oh well always next year.

 

What kind of dyno is that?

 

Dyno dynamics

 

Trap can DEF go up. 490 on a DD I trapped 126mph letting off slightly.

But hold your head up, 11's first time out on a new setup, new tires, you will get there.

Very well done! Keep going to the track. Anytime you go and can drive the car home is a good day for the FI guys!!

 

Thanks ... It sucks though because I knew my second launch was great ..I could feel it you guys know what I'm saying .

 

Oh man my bad. I didnt read your last line

Did you replace at the track and drive it home? Ive done that 45 miles from home in the dark using another cars headlights as lighting lol.

PRELOAD that drivetrain...

 

Lol I knew I was breaking them sooner or later ..and no lucky for me my friend had his truck there with a trailer

 

it sucks wen parts break...

I been interested in preloading at the line. How do u do that with a 6mt with out line locks?

 

Hold clutch just outside the friction point if my understanding is correct....wheel hop did me in my buddy watching said that's what made it go bye bye

 

instead of dumping it from the bottom out, I'm gonna try some different launches next Sunday while I still have these tires n a spare axle...

 

Switch to bias plies and kiss wheel hop and busted axles goodbye. I'll never look back since switching.

PS might wanna check your diff bushing.

 

I love Bias Ply tires. People dont get it but a sick launch on a set of slicks is like "delicate violence" lol....

I'll take RWD + slicks > AWD anyday

 

On the bias ply do you get speed wobble at the track

 

I get a little rear end drift if I don't heat them up enough or the track is very poorly prepped. After a good smoky 2nd gear burnout and correct pressure they are very stable. Even M/T themselves recommend bias ply for 6MT and radials for autos only.

 

Too many variables. Some people can trap 130mph with radials up front no wobble, others cannot. It all depends on alignment, suspension and width difference between front and rear tires on a /radial/bias ply setup.

My TN setup barely wobbled, now my car does so badly. To be honest I haven't re-aligned it to see if it would help.

 

The ultimate solution is skinny's (preferably bias ply as well) up front. But like I said the hotter I get them the less issues I've had, and it's no bad enough to warrant changing the fronts. Alignment is critical IMO.

Disclaimer: I've felt the same wobble on DR's especially when they start wearing down.
