Hi - Anyone know of a source for an underdrive (ie smaller than stock) crank nose v-belt pulley to fit my 1588? Car is in HP, though these are now legal in IT IIRC. Thanks, Al Seim

Anyone know of a source for readymade underdrive crank pulleys for a VW 1.6? This is for a Prod engine so it is already legal. (I expect they'll be common in a year!) Thanks, Al Seim

Has anybody ever compared a Tri-Y (4:2:1) header to a 4:1 header on a dyno? My ITC Scirocco came to me with a Tri-Y. If I was building from scratch I'd use a 4:1, but I've never convinced myself that I knew for SURE that it was worth $400 to toss the Tri-Y and buy a 4:1. Conventional wisdom...

Anybody got a read on the likely impact of the new fuel rule? If I read the new Fastrack properly, the existing fuel rules are being tossed in favor of a selection of approved fuels. Is this likely to mean that IT cars will be required to run $4+/gal "race" gas instead of $~2/gal pump...

Is there any good rule of thumb for minimum clearance from tire sidewall to strut? Installing 225/45-13 Hoosiers for the first time on my Scirocco and not sure how much spacer to run. Obviously I'll install and check static gap but not sure how much tire deformation to allow for. Area where...

Has anyone used or considered using an OEM style water/oil cooler (as mounts at oil filter base) in an IT car? Sounds like a great solution if it didn't crack and has enough cooling capacity!

I've got an ITC Scirocco, haven't raced for a few years, and am trying to select a tire. From what I gather, the Hoosier 225/45-13 is the "hot setup". But I'm bothered by the Hoosier specs recommending an 8"-9" wheel for this tire. The one time I've run a tire on a rim that far below specs...

I'm in Richmond Va and looking for someone to do some cage mods to mt IT Scirocco. (Especially to beef up the tie-in between the hoop mounting and the unibody channels, which of course means welding fairly heavy steel to oh-so-thin steel. The NASCAR guys do great cage work but I'm not sure if...

I'm looking at putting a Quaife in an 020 5 speed. Looking at the Bentley manual, it doesn't look too bad but it's hard to tell. Looks like the only measuring job is to remove a shim and measure diff end float then reshim, and doesn't look like that really requires anything more than a dial...

Hi: Does anybody have a set of believable flow bench numbers for a VW ITC head? I'm playing with some computer engine sims and it's obvious that w/o some flow numbers it's shooting in the dark! Thanks!

I'm looking at building an alternate (not for IT use) budget/reliable/maximum bang for the buck "road racing only" engine for an A1 VW. No particular rules constraints. The idea is to give me an alternate engine to give my(currently ITC 1.6)Scirocco some more oomph for running some non-SCCA...
