cool! sounds like you might have a vacuum leak or something. cool thing is even with all the emissions, pulling the intake is like a 15minute job...

TheRX7Project

no... I have a RB Holley manifold with a 600CFM Holley on it. It's not a vacuum leak. It's just that it's running so rich it loads up under 1500. **** it. After it's good and warmed up, it runs excellent save for the idle at 1500. I took it to work the other day (about a 30 min drive, mostly freeway) and it felt nice. Not too bad loud on the freeway. I got on it on the way home, getting on the freeway, and the back end kicked a little when I nailed 2nd. It does tend to die if I let off when I shift, I may have to learn to no-lift shift.



I haven't taken her past 7k RPM yet, since it's a 115k motor, and I'd like to keep it running for the year at least. It needs an oil change too.



I need to redo my exhaust- add a muffler, and raise it up a little. I did the under-axle run with the car lifted up (yes, I put a jack under the rear tire and jacked it up, apparently not enough), it's a little too low to the ground. Hasn't hit anything yet, but I'd like to keep it from doing so.



But overall I am happy. It fires right up, every time, and runs decent enough that I don't feel uncomfortable driving it.

I think the under-axle thing was popular with AE86's since they have similar suspensions in the rear and it gives them that ever-so-popular jay-dee-emm spec look....but like anything the japanese made it better a long time ago (for racing).

popular here for racing! back in the day when we did pro7, over the axle made less power than under

TheRX7Project

There were dyno results mentioned stating the same.



Now I just need a new fan belt... ******* squeel.

j9fd3s

oh are you running 1 belt AND the mechanical fan? thats gonna slip no matter what

TheRX7Project

Everyone on the Axis keeps saying 1 belt should be fine as long as it's tightened right.



I'm thinking Yoohoo...

It is possible to snap off the crank nose with an overtightened belt. It is common when building up the engine to torque the pulley bolt to 100 pounds so as to stiffen the crank nose. This reduces end play a bit so is done during the build up rather than after. So the spacer length may be changed to maintain end lay at that torque. A fresh belt and some spray on dressing will reduce the noise.

It's not so much the noise I care about as it is the possible overheating. I need a reliable drive for my water pump.



BTW, no rats nest, no AC no air pump.

with an electric fan. yoohoo would work too, more belt contact = gooder
