Hi Steve,

Here's some numbers to help you out............

502291 ....... new rear lower 'flying wing' arm set
K14123-4 ... Flash pit rear upper link set.
K14123-3 ... Flash pit rear hub carrier
K14123-1 ... Flash pit insert. For stock axle size.

You may need the insert if you don't have any or as spares??

K14123- 7 ... Flash point set (Front and rear) for stock drive shaft size!

Hope this helps Steve. Let me know if you need anything else.

Don't forget, if you go to the new rear arms, you will need to run the new rear swaybar so therefore you will also need to replace the rear bulkheads and the brake bracket. Then you will also need to either grind down the hinge pins or get the shorter ones.

Default Gearing

Hi everyone,

I was wondering is someone can give me a hint on gearing for a track of 250X130, my car is running out of gearing almost at 3/4 of the straightway, i have only tried this geraings...

51-20 1st gear
47-24 2nd Gear
and

50-20 1st Gear
46-24 2nd Gear (look better but still once I reach the 3/4 of the straightway you can tell there's no more geraing on the car)

at this track there's no need to let off the gas after the straightway when you enter the sweeper. so any ideas so the car cankeep pulling all the way at the end of the starightway.

Thank You

There is a 45T second gear spur available. You didn't mention if you were using the ED trans, but if you are using the standard trans, you could go to the 20T brake, side and centre-outside pulleys made by K Factory that would help.

No ED Transmission.

What other side and outside pulleys are available?

They come in 18T, 19T(Standard) and 20T pulleys.

What motor and pipe are you using?

My friend has a mongoose, he use the old S class centax. recently he blow the clutch wieght off the flywheel and in need of new one. however we all know Mongoose clutch has such a problem. I wonder if he can put the clutch wieght (K1497-10) and pressing plate (K1497-4) of UFO clutch into the mongoose flywheel. he already has the UFO clutch bell because S-class clutch bell is too hard to find

I'm using a novarossi 5 ports engine with RD Logics turbo II pipe, and my friend G4S has the MF12 with 2602 Pipe, both cars are running out of gearing.

I'm going to try this weekend the 25T pinion, but I was just trying to see if someone around here races at a big track that can give me a hint on what to start with...

maye the 45-25 and 18-52 would work, but I don't know about the 7T difference between 1st and 2nd gear...

I know some of the Mugen cars are running 6T difference at this track.

The 7T split is probably a bit much and will usually lead to stripping second gear. We run on a large track(60 metre front straight) and when we were using the standard trans, we ran 18/52 and 23/47 and sometimes the 51/46 spurs.

The Turbo II pipe will be holding you back for sure. It is not usually used as a full on race pipe. I would suggest you try a Novarossi 2630 or 2601 pipe with the 5 fin short manifold. This will give you much better performance and will increase your top end significantly. With the turbo II you are probably running out of RPM rather than running out of gearing.

I would say this is right on the nose Pro-speed.
As Zoom says,
The pipe I think is restricting full breathing of your motor.
I would suggest the same, 2601 with either the medium (6 fin) or short (5 Fin) header.
Then see what you have on the track.
I would also say try to keep the gearing to 5 or 6 teeth....no more.
I would also get the ED Transmission. It's less arduous on the motor.

Regards,
British Menace

In the finals, I managed to stay away from trouble and had only minor bumps and bruises. This was my first race with the IDM engine. This engine had lots of power to pull the car from the corners but lacked the top end power due to a wrong pipe combination. I was using Skyline VR12, but should have used the Picco 2607 or 2617. I was already using 22T, 45T pinion/spur combo. I was getting reeled in the straight-away but I manage to draw them in the corners.
I got up to 3rd at one point but at the end, I ended up 4th place. Not bad for my first race at this track, and I haven't raced for 6 months. The best part is that I had no broken parts.

Gotta get my hands on a Picco pipe.
I have not tried the 2617 but have been told it can be a bit touchy on its powerband and the few people I know that have tried both like the 2607 better. Try the 2607 pipe. The IDM version is available from teamxspower.com They are the IDM importer for the USA. If you still aren't getting the top end with that pipe, lean it out a touch more. The engine is very fast and gets great mileage. Really, this engine is the best of both worlds. Biggest drawback is you need to stock up on exhaust manifold gaskets.

Do you have a good backup engine? I just couldn't imagine traveling to any national event with only one engine. Also, if you get a new engine, make sure you break it in. You don't want to be out on the track during nats practice blubbering your engine around the track. You are wasting your valuable practice time as well as risk getting run over by other racers.

Define overkill on price? I would not get an OS as the conrod is still a bit suspect, but the engine is pretty fast for the cost. The JL-Red dot is a good low cost engine. I have two brand new sealed Sirio STI engines for sale in the for sale forum. A normal STI and a Murnan. The STI is a real strong engine and mine are pretty well priced. ($190 shipped for the non murnan and $270 shipped for the murnan). The IDM EVO 3 is also a great choice, but now you are looking at prices at or above $300.
