[Es2] Project update...

[Peter Schulz]

Geez, I know that your guys like to hang out on other forums where you can 
post pictures.....
but its a ghost town here!

I took the CQ (still with stock 7A) to Lime Rock Park last week for the 
Northeast Audi Club driver education event.
I was in the Blue run group, which was made up of a mix of the following 
cars...Cooper S, G35, chipped A4s, 911, 930!!, M coupe, M3s, 328, S4tts, 
S2000....and an RS6 for good measure.

Try as I might, 162 hp with 3300 lbs just didn't cut it in the straight aways.
The first day was extremely hot....outside temp indicator was 108 F in the 
hot pits...Needless to say, my oil temps were 130-135 C most of the day.  I 
was running over 6000 RPM often in 3rd gear....tried to run in 4th to keep 
the RPMs lower, but 3rd seemed to be the better gear, RPMS not 
withstanding.  (K&N cone, SS airbox, and scorpion airbox may have helped a 
bit  at those RPMS)

The Ron Davis double core radiator that I got through Javad Shadzi did a 
great job of cooling the engine...but those oil temps make me want to run a 
larger than stock oil cooler once I do the conversion.   wasn't Josh 
looking into a diesel oil cooler that matched the stock oil lines?

Meanwhile, my S2 engine is still at TJMMotosport being rebuilt - P&P and 
rebuild the head. Bottom end came back from the hot tank/machine shop in 
spec, so changes there will be limited to new rings, crank and rod 
bearings, AAN windage tray, etc...the RS2 EM is going to be the major 
component cost driver, but now is the time to do that...I plan to at least 
initially run the K24, but will also look into a 3inch downpipe (Matt Rooke 
said that his 2Bennet 3 inch downpipe and exhaust really let his k24 
breathe much better).

More questions from my track session....and looking forward to further 
modifications to the chassis and suspensions as a result -
CQ is running Koni externally adjustable front and adjustable rears 
(yellows) stock ( Isprings and 205/55/16 Dunlop SP 8000 tires.  Even with 
42-44lbs air (hot) in the front drivers tire, I had significant roll-over 
on the tread (over the letters!!!) Lime Rock is 1 left hander and 5 right 
hand turns.  Some of the rollover is likely to poor entry and exit from the 
turns (need more track time!!!), but also due to chassis flex.  Part of the 
eS2 conversion will include moving the battery and installation of the B4 
front upper stress bar and  Jamex rear stress bar.

which means that my front Jamex and D&W bars will be available..

I will likely go to 300# springs from Dick Shine Racing and Bilstein sports....

Brakes?  dont need no stinking brakes on this track with so little hp...in 
fact I'm still running the stock ATE disks that Bob D'Amato crossdrilled 
for me and repco metal master pads, installed in 1997....but the new motor 
will need something better than the G60s...will have to look at options as 
I currently have 2 sets of 16 inch 4x108 rims....5 bolt conversion is ways off.

IC and bumper options?  I have an S2 IC, but no crossover pipe or bumper. 
Plan (at least in my head still) is stock bumper, B4 or fabbed cross 
member, and an Isuzu NPR truck intercooler - then I have to look at either 
plumbing the IC into the stock IM, or perhaps a modified AAN IM....

comments?
