Looks like it is moving along very nicely. Thanks for the sneek peek.

Once we get the road and track R&D results and probably some tweeks it will be ready for the market

You know us, it has to function first.

I would not want it any other way. Just remember to make it fit the "justa" too.

Any news on the exhaust?

 

I know you want a "quiet" one and I think we might be there. Even the Borla, Alta, etc. are not quiet or "sleeper" exhausts. There's a line you have to cross to get the power out of the exhaust.

My new '03 came with a twin can Borla race system on it. Leon and I swapped exhaust (he had our's) to check the difference. The noise was really close to equal, but the power he lost and I gained was very noticable

The major response we have gotten from testers is "HOLLY S**T" and everywhere I go people love the twin 3" tips.

Hope this helps,

trying to get a 250+whp car quiet on a straight through exhaust is not going to happen in my opinion..........then again........what is your definition of "quiet"?

lol............

 

I have the JCW on now, and I've heard the Borla. If the sound is close to the Borla, I'd be fine with that--in the MINI, my only long drives are to the track. I do drive it around town, so I have to stay legal... At this point, I'm more concerned about the battery box--I'm willing to trade off more noise for a diffuser friendly, non-battery box altering exhaust.

 

Staying legal is no problem, really quiet (not noticed) ain't gonna happen. Like the man said :250 whp will not equal quiet. Driving around town without horsing it and shifting at a reasonable RPM and you'll be fine:ihih:

With this exhaust you'll be able to use your HP

Is the battery box friendly version ready for prime time?

 

Hey cct1, send me a PM with your info so we can talk, or go to our web site and fill out a contact sheet

Group4autosport Diffuser and splitter at MITM

Here is a couple Pics of one of the G4 mini coopers and my mcs with the diffuser and splitter during MITM and MTTS



This diffusers reduces drag from the rear area which kinda acts as a parachute without underbelly covering, It basically covers up the big ole' gap!
waiting for a Suspension Upgrade!! So It will be lowered, front and back!!!

 

That is a lot of ground clearance

 

That looks great!

(mental note: REALLY need to save money for mods :mad2

 

Those are too cool. You guys have been playing Forza 3 haven't you? Those aero kits look just like the ones that are branded Forza in the game...

Now if you could come up with a wing that deflects air down the back of my R56 and keeps the dirt from accumulating on even the shortest of drives...

 

The faster you go the better the diffuser works and will help keep your rear window clean, just saying :eek6:


A spoiler extension or a wing that functions will help too

Mark

 

I have a wing, but not sure it is what you would call functioning. It is this style:



If it was up a tad and directed the air downwards through the tunnels, I think it would work better at keeping the boot area blown off.

 

I'd like to see a side picture of what you have :idea:

Mark

 

Can you see it here?
