My boss owns a 1.7 914 with a single carb. He is looking for a little more zip.
I forgot to ask year. I suggested going to a dual weber set up and maybe a better exhaust to add a few pony's. Any one up that way with a shop that can help him out.. He is not that good with a wrench!! Greg |

budget would be important part of the discussion and future goal for the car.
I really like the stock injection when it works but it was not cheap to sort out with todays prices and it limits options in the future. If i were to do it again i would seriously look at the dub shop throttle body fuel injection system that can be tuned for a future engine build too. |

If i were to do it again i would seriously look at the dub shop throttle body fuel injection system that can be tuned for a future engine build too. (IMG:style_emoticons/default/agree.gif) I consider that system about once a month for a big bore /4 I'm contemplating. He may not want the hassle of tuning and keeping the carbs in sync. Maybe some short sidewall tires, 195/50 series for more pick-up at the expense less top end. If he can't or won't tune dual carbs then go Fuel injection either OEM or the Dub Shop system which is pricy but comes in kit form with all parts and harness that a competent shop should be able to install. Tuning the Dub Shop kit likely to require some dyno time to get it dialed in. If he's not willing to do that and insists on keeping a single carb . . . this whole thread is moot isn't it? (IMG:style_emoticons/default/blink.gif) On the tire sizes . . . glad to see that being considered. Most people forget about tire size effect upon acceleration. No one is going to want to hear this, but 14" Fuchs were stock on 914/6. 14" forged aluminum wheels offer an effective acceleration boost by virtue of size & gearing effect. But not only that, but reduction in rotational inertia is a HUGE deal. Modern 16", 17", 18" wheels and tires are heavy and have lots of intertia that needs lots of HP/Torque to overcome. 1st gen Miata came on 14" tires, plently of good choices still out there for 14" rubber. Regarless of all this, the car will never be fast in a straight line and will always lose to a 2020 Toyota Camry in a straight line. But in the curves . . . now we're talking. |
