Rumor has it that serpent will unveil a new car for the summer of 2003 that will be 100% different from the 705.............


Did'nt they just release the 705 3 or 4 months ago..........


Makes you wonder what the heck they're doing over there..........

That's why i worried about that 17 t pulley, because all the tracks here in Puerto Rico are parking lots and they are very tight tracks, we run a championship here in 4 tracks ,, only one have a 250' of straight way , so I need that combination for the other tree tracks ,, plus that my 705 like I told you before is from the second generation and he came with the 47t and the 23t brake pulley, so i need to solve this as fast as i can because the next event is this sunday!!
So if this 17t pulley is not big deal for you , why every one who runs in the winternats is using this pulley,, i saw the track in a video and this track is bigger enough to run with the stock combination, look at the MY TSN set up sheets for that tracks of all the runners in there and you'll see

Andrew you are right about the gear ratios and the type of tracks that it benefits from. Just wanted to get the best out of the engine. I find that when run on tight tracks, the Impulse / 705 is often overgeared. In the in fields of tight tracks, the car can bog down and overheat because the car is geared too high and not correctly. By the time 2nd gear is engaged, you are already somewhere at the end of the straight and you already need to slow down.

I find that the best way to use the powerband of the engine fully is to play with the gearing. The lowest gearing is unfortunately the 15T / 18T and even that I find that it is still too high for medium sized tracks.

Agreed that you can play around with the Centax clutch spring but the wear and tear of the clutch shoes and thrust bearing will be more severe.

All other cars (V1R, NTC3, Mugen) have internal ratio of 2.5 thereabouts. I believe the GT4 has also an internal drive ratio of 2. It makes it easy for car with low internal drive ratio to gear down and get very good acceleration out of the corner and in the in fields on small tight tracks. The Mugen and V1R cars (with the exception of the NTC3) have problems when it comes to very long tracks but that can be overcomed with large pinions and smaller spurs. I believe no one sees the day to have the chance to use a 20T pinion on the Impulse / 705...

You are right about this Paul. I believe even Andrew used the 17T 22T/47T conversion himself.

I'll probably get to used the 20t pinion this weekend. Ran a 19t pinion last year. Track straight I heard is going to be about 240 feet. Goling over to Maui for their on-road champs this weekend.

Wooow, lucky you It actually depends on what type of engine you use. If you have a high revving engine, you might want the 19T instead. Good luck at the races

May use the RTU. Haven't used it for awhile after I found out Ritchey stopped his engine sales. I got a used RTO, but the piston and sleeve is worn out. I think the previous owner ran it too lean. It was fast when he had it. I wonder if Ritchey sells piston and sleeve for the RTO?

Roy, just send the piston and sleeve to OSROCKET (John Bohland) and have it squeezed. I have done this to going on 20 engines (I have 15 cars and many back-up engines fo on-road and off) and they all work flawless and the extra is that for the first 2 gallons you have much more bottom to mid punch with the original top end!

#801256 17T Pulley/flange is a part that I found in a new Parts List that I have. It maybe a typo on the part number.



Thanks for clearing up the confusion......
