Three playing fields in USCAI, the purpose built, just write the check approach owner, the long time non pro racers with some sponsorship, and the Company cars built to sell products.

There is another class of the more grassroots build on a realistic budget, that the TV show likes to highlight. The reality is, you don't win without being in a full built race car with carpet and lights installed, and a serious wheel at the helm.

Thunderhill was a blast! And the Siskyous....where have you been all winter? Not a drop of the white stuff anywhere!

Sparky it sounds like we're headed in the same direction. I'm looking at running Pacific and the Ridge as well as Bremerton...you've got a head start as I'm still putting my junk together. Hopefully I'll be on the road by the end of April and signed up for HPDE shortly after.

I'm not looking to win anything. I just want to be better than the guy who's in last place...just a dumb girl in her 50 year old secretary car lol.

Ugh. It was too much of a gamble, and really too far for us. I'm trying to lobby them to bring it back to PIR next year There's a HPDE at The Ridge 5/7 with Hooked on Driving that I'm going to - maybe swing by at the least, say hi, and hitch a ride! :-)

Portland was.....not very successful last year. We joked that at least everyone finished in the top 20, hard to run this kind of program with low numbers.
I did hear some chitter chatter at Thunderhill about Oregon Raceway Park, I've never been but it is a bit closer.

Could've been that, at least around here, I was the only one in my circle of track friends that even *knew* about the series. Thunderhill adds another 2 total days of travel - and expenses - for me.

I guess my biggest gripe was, if you're going to move it south to CA, move it later in the year (so we don't have to worry about little things like towing in the mountains in winter). :-)

Only can see the first pic, but yes - that's what I'm thinking. The hunt begins!

I dont know if the 65-66's used the core support seal like the 67 up AC and big block cars did but it's only about $20 and can be glued in place. I know temp wise it forces more air through the radiator ,it will also prevent air from packing up under the hood.

The 67 A Sedan Shelbys used it.

i would focus on preventing air to enter the engine compartment BEFORE worrying about getting air out. a hood extractor that covers the entire radiator will be the most effective. (see pics) one pic shows the extractor is not very thick so it fits in between the engine & radiator.

Good call on the core support seal cyclone03 - it's an important piece that is often missing on vintage Mustangs. It does a good job preventing air from running under the hood. From what I can tell it's the same part number for 1965-1970 Mustangs (RADIATOR SUPPORT TO HOOD SEAL, 1965-70).

I agree. An extractor like in the link might be impractical, but definitely the best. A chin spoiler with a short tray under the valance will help keep air from going under the car. Blocking everything in the core support other than the radiator helps too. Instead of removing the hood scoop, build a tray that seals it to the air cleaner.
