**checking pockets for $.02** I kinda like that small Utah track! The only thing I'm wondering, is why are y'all running 2-speeds? You could convert a regular single speed buggy, + 9port :-) , and the right suspension set-up = $$$$$$$$

Wow, all this talk of guys running 9 ports and mod on-road engines in GT cars....
What's keeping ya'll from just moving up to the "F1 of R/C" 1/8 on-road pan car?

I am not advocating that less ports is superior, but they do make power fast than more ports. I have no doubt that a properly clutched/geared 9 port is superior in power to a 5 port.

But on a dyno side by side the 5 port will make power sooner than the 9 port.

Love the discussion we were having but we all know what is about to happen so I am going to sign off. please PM me so we can continue Or anybody else!!

No really.... that's not an answer.

If you have to resort to running a $$$ 9 port in a GT car at races, why not just race in the 1/8th scale pan car class with the big boys?

Good discussion, I'm not technical about engines. But I like running both 7 and 9 ports. Both clutched the same. Only difference for me is 9 has better top end. I usually gear down 1tooth on the spur for 7 port to get the same top end.

Northeast we run open GT, so don't ever see using a 5 port. As tracks are big.

There are big boys in GT, 1/10 and 1/8. Why do you keep flaming things. We get it you like racing GT's with 3 ports, so have fun.

I can only speak to my area open GT is only preferred.

Jermaine,

You must be misunderstanding my question, because I’m not flaming anyone.

I was just trying to understand why anyone would spend big money on a 9 port on-road race engine, send it to a “engine mod” guy for more tweaking and drop it in a buggy based GT chassis, when awesome 1/8 scale on-road pan cars exist for those engines.

I’m just asking a simple question, in the hopes that some of the “pro & sponsored” guys racing in the GT class will answer.

Why aren’t you “pro & sponsored” guys racing your $600 to $800 on-road engines in the chassis & class they were actually designed for?

First your was post was not poised as a question, really a continued sarcastic way to protest your opinion on open GT.

I'm not a pro or sponsored, but really doesn't matter. For me racing GT is fun and not as fragile as 1/10 and 1/8 but I want the the same speed without the headache of cutting tires constantly and other things that are involved with the other classes.

Thank you, finally an honest answer without any personal attacks made against me for asking why you don't want to race in the 1/8 scale on-road pan car class with a 9 port on-road pan car engine. Thanks again

I have a ISON motor will work well at my home track LH, but I may get a modded motor to, for bigger tracks and even LH. Cause my car will handle like a 1/8 Yes Mike Lyday its gonna be fun.

Hehe ... I can see you are openly optimistic about your new car Pete.
Should be a fun year with all the new cars and experience gained from past years of running GT bearing fruit I feel.

I have put quite some effort into building my car and also hope to see her do well on the circuit.

Regards
BM
