I have over 10 years of chassis setup experience 80% of them being BMW and never have I needed to go anything more than full soft setting on sways with preset adjustments. On the race sway bars which are hollow bar slider/blade type the most we’ve needed was ~10% over full soft. For street...

Seeing the amount of AOA he runs on his 3D element should deter you. Lol

Whiteline offers a sway package with front & rear sway links, that allows you to dial out any preload on the sway bar. Car will need to be on a 4post lift or race stands to properly adjust them.

Correct. I didn’t want to fully seal the inlet trumpet with a 3” diameter hose, just wanted to direct some fresh air to the inlet. However we might try to cover the whole trumpet with a 4” hose. I thought about pulling air from the side of the radiator cowl but didn’t want to take away too...

Will easily be $10000, if you want to keep the DI and run PI all MoTeC controlled. You’re gonna need 2 ecu’s, one for DI, one for PI. That’ll be $6500 in hardware alone, excluding breakout boxes etc If you’re willing to ditch the DI and run PI only the M150 supports 12 injectors, that’ll be...

Spacer size depends on offset/width/tire size for clearance to the spring perch/damper.

Yea, have him message me.

He should try the stock mppsk map for the track if he’s overheating. Does he have any logs?

I don’t recall at the time, I had first delivery and installed the jb4 right after break in period. Kept getting spark blow out at the track, I ended up gapping the plugs to help with the blow out.

I ran a JB4 on my F80M3, had first delivery and back then the tuning options were limited. After about 5k miles, lots of high rpm misfire/spark blow out. Never will I touch a piggyback system again.

Air temps coming out the compressor side average about 200-250F. Exhaust gas temp average about 800F+. I didn’t have a temp gun to measure what the temps are off the manifold. If you plan to do some testing grab a temp gun for the sake of science. The goal was to contain the heat radiating off...

Yup, except for we’ve upgraded to brake ducting.

Saw an average of 10-15deg higher IAT.

High speed or low speed under steer? I would do damper adjustments before a rate change. Also any data on the hood scoop yet?

Made a proper insulated heat shield and intake snorkel today that directs air to the air box inlet you’re talking about. Results were over a 10F drop in IAT. Can read about it here: https://www.supramkv.com/threads/diy’d-a-manifold-heat-shield-intake-snorkel.18838/#post-297487

Heat management is a must for turbo powered engines and we were looking for a heat shield that would keep the heat away from the turbo compressor housing, didn’t see one on the market so @suptj & I made one. The heat shield runs full length and is butt up against the cylinder head on top and...

Fixed back seats without a 5/6 point harness is dangerous. If you were to get in a collision, there is a chance you would submarine due to no crotch strap. To run a harness properly, you need a roll bar… so these 3 things come in a package if you care about your safety.

Not true. It depends on the tune, at e53 the hpfp is holding up perfectly fine, zero signs of crash. Logs show hpfp angle in the high 90’s, max angle on the pump is at 126… so there is room to play with.

That would be a flex fuel tune. Set your base fuel map and with an ethanol sensor it’ll scale your tune according to the E content that it’s reading. With stock fueling you’re gonna be limited to ~e60 depending on the tune.

I haven’t driven on a street tire at the track for a while but when the ad08’s came out they were the fastest tire at the time. Amazing sidewalls on that tire, gave great driver feedback.
