My favorite is 100LL Avgas. (1.6 LP HP VW). Half the lead of most race gas, long shelf life and highly consistent, and typically quite a bit less expensive. What's not to like? Can be hard to buy as it's illegal to sell for street use so some FBOs interpret that (incorrectly) as only allowed...

There - I created a real data acq tech discussion thread. Greg - have you used that dual channel Bosch sensor? It looks intriguing. It does appear to have an unusual taper seal seat near the nose, but looks as though it might work with a regular copper washer. I agree with your sensor...

Trying to unhijack the FP Runoffs thread: Correct me if I've got this wrong, but it's my understanding that there was a rules interpretation ruling at the runoffs to the effect that the general allowance to coat driveline parts extends to intake manifolds, in this specific case, the exterior of...

Is Red Line CV2 a good choice for a very high temp wheel bearing grease? I've discovered that my VW wheel bearing cartridges come apart easily w/o damage so I think I'll replace the stock grease with "better" as everything in that area is HOT. Is Red Line CV2 a good choice? It shows a workung...

This one qualifies for the department of outdated technology - I run an HP VW Scirocco 1.6, and like many folks run a bit sporadically. A few years ago I had a pretty good setup on 8x20x13 Hoosier C2000 tires, the car handled well. I took a few years off and came back last season using C3000...

Hi - Installing a right side net in my VW. What's a tidy way to limit the straps from sliding sideways along the cage bars w/o welding? Al Seim Race Technology USA HP VW Scirocco 1.6

Who's coming in Prod and GTL? I am. Al Seim HP VW Scirocco 1.6

My HP 1.6 Scirocco is too close to the sound limit for comfort so I need to revise things. Right now it's running an L shaped system, 2.25" pipe, exiting in front of the left rear, with a short bullet glasspack (Dynomax) in the short leg of the L and a turndown on the exit. Turndown is within...

Who's coming to MARRS 4 at Summit Point on June 20-21? WDCR doesn't charge the credit card early any more so it's safe to register early. I haven't raced for a couple of years so need some prod cars there to help me remember which way to turn at the end of the straight! Greg, Frank, Mike...

Just saw a thread on another forum that got me thinking - Should stainless steel braided brake hoses be considered a limited life item? And if so, is it hours/cycles/years that kills them? Sounds silly, I suppose, since I guess most things do not have unlimited life, but honestly I've never...

This is a topic which has been touched on several times, but not recently as a standalone topic..... How do you think SCCA (ie advisory committee and CRB) should ideally handle Prod class performance equalization with respect to performance on various types of tracks? What I mean by this...

What brake pad materials do you guys like these days? Specifically, I need to upgrade to something "better" (ie works at higher temps) than good old Hawk Blue? My HP Scirocco will only go for about 10 hard laps at Summit Point before starting to pick up pad fade. I've got good ducts and cans...

At SCCA.COM Volvo HP engine size/origin already fixed, now explicitly says P1800...

Poll question is simply: Should SCCA Club Racing mandate or encourage all Regional and National impounds to be open hood for door-slammer type cars? I say yes as it adds "daylight" to the process and discourages gross violations or the perception of gross violations. Kevin says no as it...

A few years ago I installed a "mini-Denso" alternator in my HP Scirocco, identical in appearance to the smaller units at: http://www.powermastermotorsports.com/d ... ators.html I'll confess that I purchased elsewhere and maybe that's the problem - I've gone through three of these in the last...

Another great Prod field is shaping up for the Labor Day MARRS double at Summit Point this coming weekend, registration tonight shows 4 EP, 6 FP and 7(!) HP cars so far. Any fencesitters should come on out. Forecast is for no earthquakes or hurricanes.

OK, I'll take my own advice and say something positive - that also happens to be true! The HP class at the Summit Point / WDCR MARRS regional series has gotten stronger in the last few years, and represents a great fun racing opportunity. The MARRS 5 race this coming weekend (likely the lowest...

Next exciting inquiry - On at least one factory high performance engine (Ford SVT 2.5 w/ extrude honed ports) the head intake port inlets are slightly bellmouthed (maybe a 1/8" radius?) presumably to make things less sensitive to misalignment upon assembly. Given the difficulty of exactly port...

I'm having a VW 4 cyl crank balanced, it's being sent out by my engine machinist. For the first time (I have not had a crank balanced for a while, btw) the balance shop wants to know the piston, pin and rod weights. Engine shop guy, who works on mostly V8s but also I4s etc, says that the...

My old K&N filter on the HP Scirocco is looking a bit frayed, seeing some gaps in the cotton media - maybe just age, maybe somebody used compressed air on it, dunno. There seem to be several brands now of washable media filters - is K&N still the best, are they all the same, or? Has anyone...
