I know that there is alot of things about cams and stuff that people have questions about but... does anyone know about web racing cams? I don't think that they have any products out for the 450r but does anyone know about them. soposidly they are more well known to the dune buggy and lt buggy crowd. but does anyone know much bout them. I would bet that they will have a cam for the 450r pretty soon with sparks hotcams and honda itself having one out.
thanks

BIG....... it was a big cam with big vavles and the increase was huge on the cams part.... with their cams though the piston has to be re cut and butterflied for the increased valve movement..... they are not drop in cams........

Unfortunently i cant give you exact numbers on the gains because we did everything at once and didnt take any "In the Middle" readings.... it was just before the 440 kit.... 23hp 21ft/lbs..... after the 440 and big valves.... 38hp 29.6 ft/lbs...........


I cant wait till i rebuild it with my 13.5 comp piston..... it is going slow cause my engine builder is selling his house and trying to add on to it at the same time...

I talked to web a few weeks ago, you might try calling them because there cams are most likely done by now. When I talked to them they said they were working on 2 different ones.

BTW Web makes the cams for LRD in case you didn't know. Also web has a core charge also, I think its 150 bucks so don't lose the stocker.

I dont like HIGH REV CDIs

Web Cams does make quite a few grinds for the crf 450 and trx450. They have one grind in fact that works real well in the trx engine it is there 493-729 grind it does require different springs though. There is another hotter grind 208-729+5 but i would only use it with at least 13-1 compression and head work. you can find there web site is www.webcamshafts.com. ask for debbie or laurie they are real helpful.

Yeah the web cams work great, I'm here in Wichita Kansas and the guys at n motion race technology only use web cams in the trx450r and their bikes rock. I know they can answer any questions if you need to as well, 316-262-8900

:wacko: I don't think anyone could lift the valves on the exhaust 1.4". That would put the valve half way down the cylinder bore if it did. The Hot Cam lifts the intake 10.1 mm, that equates to roughly .398", or slightly more than 3/8" lift. And that is a lot of lift.

Who measured these cams and how did they measure them?

Also, why would you harden the rocker on the TRX450R? It has a roller on the end of the exhaust rocker arm so it rolls on the camshaft, there is nothing to harden. And the intakes are direct lift shim under, buckets. No need to harden them either.

The sparks measurement was made at my request by a guy from exriders. He measured the whole lobe entirely from top to bottom, that's the reason for the large number.

Tice as far as rocker hardening I'm going on what I was told by a guy at sparks. For there "full race cam" they said it is not a drop in and hould require you to buy there kit seperately with springs and rocker. Mabey they were refering to hardened buckets although that's not what he said, he said rocker which doesn't really make sence to me either. I guess the next time I talk to them I will get more info.
