Umm... I think my E4 has a 35 and a 17 for a 2.0588 internal. But I didnt count the teeth on them. So please tell me Wolf, since we are running it 4.2 final its important that I know if all my small pullies are 17 teeth or not.
geez man I sure hope it is 35/17. I have the E4 C1 optimized for rubber.
Thanks in advance Wolf.

Thanks to Jonny Socko for the reminder. This has been mentioned a few times but the thread is getting so large it is really hard to backtrack through the whole thing.
There have been a lot of questions about pulleys. Not all of it has been accurate. There are two internal ratios used on the E4s. The E4FS uses the 1.8 internal ratio and all of the others use the 2.0. The E4FS uses 34 tooth pulleys on the diffs and 18 tooth center pulleys. All the rest use 35 tooth pulleys on the diffs and 17 tooth center pulleys. All the cars use 17tooth side pulleys. Side pulleys and center pulleys are not interchangeable.
The manual has an error on the part number for the 17 tooth center pulley. The correct part numbers are as follows:
503155 35 tooth diff pulley
503201 34 tooth diff pulley
503197 17 tooth side pulley
503222 18 tooth center pulley
503236 17 tooth center pulley
There has also been a lot of talk about mixing and matching pulleys to compensate for belt stretch. We have tried this and have not had any good results.

Got a few questions for you. Sent you a PM.

Had a great of practice today, made very small changes to my previous set up, just took out the rear sway bar and added a little more camber in the rear (-2.5) the car was really good with the 4.5 mod motor and very good with the 13.5. Ran the jaco blues ( our hand out tire for our state series and rp 36's. the car was a little loose with the jacos with the 36's the car was better. I also tried 1mm shims under the front and rear arms , the car reacted left to right alot better but was not faster. I went back to the arms flat on the chassis except in the front of the rear arm , i kept the 1mm shim in the front of the rear arm.

I'm actually looking to start back into touring after my almost 2 year layoff. Are electric 1/10th scale track is just not up to par so I'm going back to touring.
Should be running in a few weeks.

Marcos when you say the car reacted better from left to right are you talking about the initial turn in. I will post my setup and try the shims under the roll centers this friday. I ran car last friday on the carpet and it was sooo consistent. i will post that setup as well. i was running jaco blues on carpet and rp36 on asphalt.
