    More wheel photos on my Gen 5

    The back space is not the only issue, the the outboard side of the caliphers could interfere. In other words isn't the G5 calipher deeper.

    Intake Air Temp question

    If the the G5 has the same a/f versus rpm table as the previous generations it can benefit from leaning out the a/f at high rpm and wot. The G4's have seen hp gains by fooling (adding resistors) both the IAT and ECT sensors. Give Sean Roe a call and discuss it with him. This is where most of the...

    It does not matter. [WowQUOTE=MtnBiker;3198133]Basic rule...the clutch should only be engaged to change gears, and for as little time as necessary. At lights put it in neutral.

    Clutch Wear Question

    Bill You never drag raced a viper. Put drag slicks on any viper and clutch life goes down dramatically. If you don't drag, correct, it is a non-issue.

    Intake Air Temp question

    High IAT = less hp. In the past CC would throw more fuel into the engine, therefore, less hp again. The G2 over 5000 rpm would routinly run 11.5 at wot when the temp was over 80 deg.

    Intake Air Temp question

    The short answer, the probe of the IAT sensor is hotter than the actual intake air (not by too much) because the probe itself is not totally insulted/isolated from the engine bay heat. That added heat is primarily convected and conducted heat that enters into the sensor body from the engine...

    Pirelli PZero Corsa vs Michelin Pilot Sport Cup

    The 355 is really 27", for some reason the advertised diameter is off. When I put the 26" drag radials on my car it did not seem to care.

    Ralph Gilles' Dyno Results

    The Dynojet is very repeatable over long time periods. If you look, Ralph used the SAE correction and a low value of smoothing, that is very common, therefore, that should give you close values from different locations. The point here is that Ralph's car is putting out about 48 hp more than...

    Ralph Gilles' Dyno Results

    Temps do not matter a lot, those are corrected numbers. Usually in cars with half shafts or CV joints you see 15% losses. Most of these cars have been around 530. That is way diff from ralphs 578. I will dyno mine within the next 30 days - we will see.

    Can the Gen 5 Autocross - A Primer

    I would estimate the course at 1/2 mile, it was not long. There were 3 sets, within a set you raced approx every 4 minutes. My best time was a 31.1. There were two places where I consistently hit the limiter (64 mph).

    Can the Gen 5 Autocross - A Primer

    You cannot tell you have stability control, it is so non-intrusive. It is probably more apparent on a high speed road course. The launch is a problem though, you have to shut off stability to get any sort of launch.

    Pirelli PZero Corsa vs Michelin Pilot Sport Cup

    I drove 800 miles in the rain with the P-Zero's, they are excellent rain tires. I ran an autocross course last week with the P-Zero's. We ran the course 13 times. The tire on the outside shows definite track usage. If anything the tire performed too good for a street/race tire. I started to push...

    Do You Know How Hot Your Sills Run

    Fluke just released a $1,000 camera, however, those are low resolution. Do a Google on a Fluke Ti25 (predecessor to the 125 or ti10), see if you can find a used one. I have some pics of a plugged cat, those are crazy.
