buttlips, you prolly right about the 13B power in IT trim. I was just taking a guess.

You may be right about an ITA car, I was hopin an ITS built SE might fare better. At the last divisional, I came in a distant second to Heath MacMillan (4 sec behind). Nipping at my heels in third was an SE prepped to CSP. I aint a great driver either, fair to midland I'd say. I think It depends on the course too though. On a fast course, like at a SOLO Trials we had back in april (same track), I ran in IT7, cause I spanked all the CSP cars by 8+ seconds IIRC.

Well if I DO remember what I had with mine,, then I may indeed have a TC / Trans. problem. I actually thought there may be something wrong at the time, but like I said, it was my first, so I didn't have a comparison. That's why I included the "IF"s....It took 1 1/2 days to get it running so I could get it home! Of course, I only paid $300 (and got the signed title first) because the shop where I bought it said it was shot and towed in
Chuck, the real comparison we were debating / questioning, was a "13B (SE) prepared to IT,,, vs. a 12A prepared to CSP,,,running solo"?.... Thought you might be more versed in BOTH areas for rules. The only "automatic" I have Soloed is the 85 Charger mentioned above. (although it was FWD) I found it much easier to keep balanced with "LFB" than I have been able to do with the manual "7", hence the experiment!
I still want to get you guy's "prefered list" of componants for an IT 12A. I talked to Charlie about it last year but never called him back when I knew I had to put it off. I haven't been to the "Nationals" for several years. Is he still running the Corvair?

racermike

See how slow I am! your post wasn't there when I started!

Because of the better induction allowance in CSP vs the stock stuff in IT (if I'm not mistaken you can run a Weber in CSP), I would guess that a CSP 12A and an ITS 13B would be very comparable in peak HP. However, the ITS 13B should have better bottom end and a more usable power band, and therefore be the better choice.

Yep, Dad is still autocrossing the Corvair, but it's been retired from road racing. He finished 19th out of something like 65 CP cars this year's Nationals.

By the way, he is one of the 8 or so drivers that have competed in all 30 SoloII Nationals!

racermike

Yeah the 100%ers are few now days. Susan Anderson here is another. They haven't lost but one or two I think in the last decade or so! We should start a "pool"!
Well that's about what I thought power wise,, except for CSP I think it is unlimited for intake and exhaust (and port matching within 1 inch?). At least it used to be. I ran the Holley 650 for 3 years when it was in ASP. I know, I know,,,,,tooo much carb for the low end,,,,but I lived above the red line anyway! I also thought the 12A would rev a little faster and live a little better at the upper limits.
With that in mind, thats why I want to try the 12A, auto, with a high stall speed TC. I would sacrifice the low end which isn't any good on a rotary anyway, and keep the motor turning in the 3,500 to 8,000 range. Big carb and I already have the RB "street port" exhaust, (twin long tube header with 2 "power pulse"). I think I can make it breathe ok,,,,if it stays togather!

racermike

Oh, and I still have 4 bodies with no titles,,,,which is why I want to know the parts list for a 12A in IT,,,or maybe "Spec 7"???? Did they pass that for Midiv??

Rx7carl

Good points buttlips. BTW whats your dad running? Obviously a late model, but whats he got in it? Fitch sprint engine? 140? I have a 62 and a 64 bathtub style .

Maybe I'll do some work to the POS and autox it this year......ANyway, reacermike we're getting off topic, but what are you specifically asking about a parts list for ITA? I dont understand what your wanting to know.

racermike

Well buttlips and dad have been road racing 1st Gen 7s for a while. I'm just looking to start a wish list / shopping list for componants to put an IT or Spec7 together. Obviously in those classes the list isn't too long, and I just want to see what they prefer. I've watched the action for a looooong time from the corner stations if you know what I mean! Sooner or later I will be too slow to sprint 100 yards across a hot track carrying a fire bottle! I actually started competition on circle tracks (don't laugh) 26 years ago, 1 year before I found Solo. I dig wheel to wheel as much as Solo, but I have never "offically" ROAD raced.

buttlips

Mike,

Give me a call. The wish list might be pretty lenghty for posting (I don't type well). There really aren't any secrets. My guess is most of the good ITA/IT7 cars have all the same stuff.

Unfortunately, the IT7 class didn't pass this year for our Division. I was just elected RE for the KC Region, and I intend to press that issue at next year's meeting.

My phone number is listed on the contact list at kcrscca.org

racermike

Bummer, I guess the Miatas are taking over the world!
I'll call,, no real hurry.
Thanks
PS my condolunces for sitting in the "hot seat"!

buttlips

Oh yeah, I didn't answer Carl's question.

My Dad has a 1966 Yenko Stinger. It's not a "real" Stinger, but one of the kits that Don Yenko sold with the VIN plates.

He builds his own motors. They are Corvair motors that are built up. They get 260hp out of them naturally aspirated.

That car is a rocket in the rain! Ralph Nader can kiss his ***.

Rx7carl

Oh how could I forget about Don Yenko! I used to drool over those cars as a kid. And damn straight, the late models handle with the best of em!

AJC13B

When I had an auto in my car, it had a full manual shift and a 3000rpm stall convertor. Was nice to drive around with the small turbo and did a 13.9 on like 10psi and 14 inch street tyres! The car had the auto in it when I bought it though, so I can't really help! Sorry mate!

racermike

I think the stock stall speed is 2200 - 2400 (??). So you did not mod it yourself?? How was the car (at that stall speed) as far as getting into the meat of the power?? I have been hypothisizing that I might need to go to 3200 or so for my aplication.
Thanks for the reply, ANY insight is appreaciated!

Rx7carl

Well the FSM says if the stall speed is too high, then look for low oil pressure. I dunno if that helps at all.

racermike

Now that racing season is here, I wanted to try again to see if anyone has any experience in an automatic, 12A, at Solos. The "experiment" is to modify the torque converter for a higher stall speed. Drag racers may have the insight I am looking for. As stated at the begining of this thread,,,,,I know what all the negatives are and I am VERY experienced in autocrossing and 1st Gens. I still want to do this experiment anyway.
Has anybody any experience in modiffing TC or trans on a 1st Gen 12A, or have Solo experince in same??
THANKS
