grudge chassis

[Rick D]

Someone please explain what a grudge chassis is and maybe how its done. Right now I have a stock wheelbase gen1 with a stage1 turbo with about 9#s of boost in it. I was just wondering what difference a grudge chassis would make??

 

[Commuta_Busa]

a grudge chassis is purpose built for the combo. Super light and lean with a mega stretch are simply the visual changes.

 

[Rick D]

When you say built for the combo what do you mean by combo?

 

[Commuta_Busa]

Grudge bikes have very loose rules if any. There's no max wheelbase, no min weight, full slider allowed, etc. You would setup the chassis on a turbo bike different than a NA bike because of the way you're laying the power down.

It might be better if you explained what you're trying to do or accomplish... Are you looking to compete with the grudge crowd at the tracks? If so, the stage 1 turbo isn't going to cut it.

I've only had the turbo on it for about 4 months and I'm a 130# rider. The reason I post the ? was I read on another thread that you could get in the 8's easy with a grudge chassis. At this point in time I run a wheelie bar at the track and trying to make the decision on whether to extend it or not.

 

[Commuta_Busa]

if you've got a wheelie bar you should also be running a slick no wheel base extension is needed. A bar bike with a turbo should do 8's no problem. Swap you clutch out and do some pushbutton shifting.

FYI: You don't need a wheelie bar or a grudge bike setup to get a turbo busa into the 8's.

I do run a 7'' MT slick but a stock clutch with heavy springs what clutch do you recommend

 

[Rick D]

The reason I was thinking about extending it was because of the trans is stock and I know the bar is hard on it. I been running the bar for about 3 years now a I love the way it leaves the line.

I know nothing about grudge chasis, but what kind of times are you turning with the stage 1 setup?

 

[Mr Bogus]

heck there are guys running in the 8's with stock busa's where is that post? 8.90's

if you are not close now, keep working at it before you drop a ton of $$

I have seen literally dozens of turbo bikes stuck in the high 9s and low 10's due to just bad riding/bike setups...

Contact DME they are the masters with super light grudge chassis and (de-raked) fork set-ups, not the cheapest but you get what you pay for. Good luck.

Sean06 I'm still learning how to get out of hole with it but my MPH was 129 in the 1/8. Don't remember the ET though, but to answer your question better the turbo is night and day different and worth the money as far as torque and HP.

 

[Mr Brown]

Not knocking you but it seems to me that you are barking up the wrong tree. 129 mph is far too slow to run with the big boys. With a slick and bar bike you should have no problem at all launching. Pin it and dump the clutch. Unless you have totally missed your setup it ain't gonna hurt ya....
If you are using HD springs make sure you haven't broken your sprocket cover.

If we could trust most people, there are some R6's out there that should shatter the 8 second barrier!
