For the prototype, you guys should be thinking about the ability to swap pieces easily. Let's say your plenum is the right size but you need to swap out your stacks, you should be able to remove them and replace them with the new pieces. The finished product should be one piece to reduce turbulence. Prototyping is always easier when you can take it all apart.

I'll powder coat the prototypes for you guys if you'd like.

Check for chassis stress cracks around the rear subframe mounting points

 

 
 
 
As for raising the rev limit to 7200:
 
When you search around the M50 family of engines doesn't take well to high revs without substantial modifications.
 
Engine harmonics potentially killing the crankshaft (requires proper harmonic damper at minimum)
Hydraulic lifters
Soft valve springs
Cylinder head flow
Oil pump flow
 
7200 rpm probably isnt high enough to worry so much about the items listed above but with any engine, theres the additional ring/cylinder wear from high piston velocities.
Mean Piston Speed  
------------------ ------
Under 3,500 ft/min  Good reliability
3,500-4,000 ft/min   Stressful, needs good design
Over 4,000 ft/min    Very short life 
 
http://www.unofficialbmw.com/all/engine/all_redline_rpm_vs_reliability.html
 
Piston velocity pertains to ring and cylinder wear and has a linear relationship with rpm.
A stock M50 with 6500 rpm redline  has a mean piston velocity of 3257 ft/min
raising the redline to 7200 moves it to 3607 ft/min. . 

Unfortunately the inertial loads in an engine that cause rod/main bearing wear and crankshaft/connecting rod failures increase with the square of  rpm.
So while 6500rpm to 7200rpm may not seem like a lot, the stress on engine components is 49% higher at 7200rpm vs 6500rpm. 

For full throttle rage drifting purposes this will probably list the engines life in hours instead of miles. 

in my opinion, the additional performance had from the extra 700rpm is not worth the decreased engine life. You may be able to bounce the car off the limiter for a few years worth of drift events  at the stock limit whereas you may be lucky to get through 1 season at 7200.
 
More time enjoying the car is always good.

No.

Thank you to all that attended! as always there are a few things that I feel we(the GTG crew) could have done better at but in my opinion this was the smoothest scooters yet and that is mostly due to you, the guys and girls that attend. Every one seemingly had a good time and was very respectful of other enthusiasts, staff and most importantly our hosts/neighbors. We could not put this event on with out your attendance and we could not continue to host the GTG without everyone playing by the rules. We also had a best yet turnout for BMW's and that is something I personally like to see so thanks and if you have any suggestions or comments about the event I am all ears.

black '98 318 gets 24-26 once on a trip it got 37.8 but i was sleeping in the back. the green 92 325 gets around 17. the red 93 always got around 28 the grey e23 was getting about 22 the green v12 got a little better than 18 and the grease-burner swaped chevy got 22 to 24. the 2 Audi's got about 1 balljoint per 600 miles

industrialsized's hella hooptie was best in show!!!

Camping out of the wagon this year.

I am in favor but I have different motives... Sack the man who decided to NOT bring over the euro e36 M3!

One of those guys was sentenced to death by beheading for killing two spectators not too long ago.

I added a content warning FYI. 


One time at lunch I stabbed my burrito with a fork and Chris started tearing up and dry-heaving.  
You just dont know what some peoples comfort levels are. 

Have either of you driven a 5 speed X5? If so, you'd probably have a different opinion.

^google images are a great source for Craigslist pics haha

Looks like two different cars in the pictures, ones got body colored mirrors, dents on the fender, and what looks to be a later style valance while the other has black mirrors, an early valance, and looks generally cleaner. 

Dustin hit the nail on the head...
 
We had a huge turnout at the last colgate meet. After that it dropped off. After all the exposure you'd think we'd be larger than we are now.

thanks to all that showed and screw you to those that didn't. it was great cheap fun just like last year and it's a real shame so few make having fun with their cars and like minded enthusiasts a priority only to sit on the internet and complain about how the scene sucks in the Midwest.

Do you have pics of the dip tank?  I always wondered how you guys did whole cars.....that's gotta be a huge tank.

The biggest con being no telephone # and a seller that doesn't return emails.
