Matracer's project: BRONZIT S52 - DYNO RESULTS P.8

[MatRacer]

I'm trying to think if I've had that problem with mine, and I think with the new Konis I got I haven't noticed that issue.

Yeah, the koni are harder than the bilstein... hope it will help my case

Sucks when you break stuff but it gives you an opportunity to make things stronger

how do you know that??

never been to the drag strip... I get wheel hop when it break loose on hard accel at like 5000rpm in 1st and a bit higher in 2nd when its cold outside (running 225 RS3). If I lauch very hard, no wheel hop but if I lauch semi hard, then I get some.

Also, when I get a taste of sideway fun, if I don't hammer it, I also get wheel hop.

Its worst on wet pavement.

Its, possible to avoid it, except when your getting good traction and it break loose at higher rpm in second gear... pretty annoying...

My bilstein are not new, got them used with unknown mileage... So it wont hurt to replace them anyway. Also planning on increasing spring rate.

Were you drag racing to get wheel hop?

Update



Driveshaft in the trunk means broken driveshaft... had it rebuilt like 1000 miles at a local shop but they apparently installed ATV joints... that combine with wheel hop was enough to destroy one of the needle bearing... also, they machine it a bit so it's now not possible reinstall oem type joints...

Fortunately, scored an e36 328 driveshaft for 40$!! Will get it this weekend. If I'm lucky I will be able to just throw it under the car without rebuild...

Wheel hop it really annoying and probability hurting more stuff that just the driveshaft... sublease is solid mounted and got poly TAB... the rear end is on 500 pound spring and bolstering sport shocks... will replace them with Koni. Hope it will help.

Is poly engine and tranny mount would really help reduce wheel hop? Read that somewhere but really not sure about it...

Another one!!

Wow, looks like you're having fun with this thing! :D

My S52 goes in soon, are you enjoying yours?

Sure do!!!

Really like the S52! The sound, the power curve, just enough to have a lot of fun on track event!

However, I'm running it with OBD1 and I have slight pinging between 4 and 5k rpm at WOT.... My chip is form TMS. My guest is that I'm a bit too lean in this range (vs fire timing advance)... Will probably go with a custom tune next spring.

But else than that, its a blast!

Liked how it was sitting in the driveway this morning

One more from track day.

Way to much roll

Knew my suspension setup wasn't optimal for track usage and that I got quite a lot of body roll, but zooming at this picture made me realize that it was worst than I thought...





Basically, I have 300# fr and 500# rear with stock sway bars... since our roads are really bad, its good not have too stiff spring... but for track it sucks... We will see what I will do...

[MatRacer]

New steering wheel!



Also, when to a track event last week! Everything held! Was really awesome to finally hit a track day!
