Geez, I know that your guys like to hang out on other forums where you can
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....
