Opinions follow...
As much as I'd love to see a 914 competitive in Prod, I think out would HAVE to be a labor of love. Here's the results from the 2023 Runoffs (check out that guy in an EP Civic that only made it 1-1/4 laps): https://www.scca.com/pages/2023-scca-runoffs-results E Production: Big engines class. 2.5L BMWs. Maybe a Z car with a Rebello engine (if it were driven well, unlike the ones I was racing with mid-pack). 2nd-gen Mazda RX-7s driven particularly well (like Hainsworth's). Your engine builder will be your best friend (and you, his). I just don't see a 4-banger full-prep Type 4 2L bringing the kind of numbers needed to compete in EP, especially since the '24/'25 Runoffs are at America's Dyno, Road America. Even with a 600# weight advantage - assuming you can get it down to 1800-ish with driver - you're going to need 225+ ponies to compete. And it'll be fragile. As noted above, Kip van Steenburg has a 2L 6-banger that's showing potential, but it's fragile: it appeared at the 2021 and 2022 Runoffs but was withdrawn during the test days. Watch for that car to eventually get sorted and maybe John Hainsworth driving it. F Production: Miatas and Hondas/Acuras. Miatas bring the handling and braking, Honda brings the power. IMO, it's a tough row to hoe for the 914. The 1.8L full-prep 914 has neither the power of the Hondas nor the handling/braking of the Miatas. You can run alternate brakes now in Prod (+2% weight) but you're still scrapping against those two marques. The limited-prep 2L may have a chance, given it's allowed dual Webers/Dells. Can you get a reliable 150hp for its 2030# (with driver; 2083# with alternate gear ratios)? But it's all limited prep, so think Improved Touring spec chassis with slicks. H Production: SCCA finally allowed 2L engines into HP, and the water-cooled VWs are shining there. Chris Schaafsma has won HP two years on the trot, and he has a really well built, and well-driven, Golf. Steve Sargis in the full-prep Triumph is always in the mix, as is Vesa Siligren in the limited-prep Honda CRX. But SCCA is only allowing the 1.8L 914 into HP right now, and only at Limited Prep -- and you have to keep the fuel injection (though it can be Microsquirted). That's basically Improved Touring-spec with cams. MAYBE the 1.8L limited prep has a chance in HP at 2100# (2153# if you swapped out factory gear ratios)? It would take a dedicated effort, I think, to fully develop the car - as noted it's basically a strong IT effort on slicks. I think that SCCA would eventually allow the LP 2L into HP, but someone needs to drive one in FP to demonstrate it. My historics racer is an ex-ITA prep chassis and the engine is very much within the specs of Limited Prep Prod. I have no idea what my plans are for '24 but maybe I'll buy/borrow an AIM Solo (it's what SCCA uses), get the engine dyno'd and the car weighed, and run a couple Regionals to send that data to the CRB for consideration. We'll see... GA |
