Thunder Racing Custom Camshaft - 230/236 .590/.598 112 LSA 2400-6800 RPM Power Band. Excellent mid-range & high RPM power. 3200+ stall, 3.42+ gear, computer tuning required

just curious.

I talked to them yesterday and they recommended that cam for my car.
Matthew told me that the last 3 cars they did made 420rwhp on stock heads with full boltons.

The two he told me about were a an A4 fbody and a Zo6. Pretty sweet that the Fbody could match the Z with similar mods and LS1 heads and higher parasitic loss due to the A4.

How can you compair an A4 F-Body and a M6 LS6. If they both put down the same horsepower then something is really wrong. There arent many if any cams with similar specs that have A4 cars putting down 420rwhp with stock heads. Thats just too much.

I was surprised...I wasn't going to argue, but I asked the same question. I said, "I said how can an LS1 headed car equal an LS6??? the guy with the fbody must be happy!" Like I said, I'm just repeating what the guy at Thinder Racing told me.

Both cars had full bolts ons, Long tubes, Highflows, Underdrives etc.

I agree it sounds high, but TR is standing buy the numbers...now guarenteeing the numbers is a different story

There must be something goin on there. If that was the case, there are plenty of other cams in the same profile range that don't put down those kinda numbers. The cam sounds like a XE-R 230/236, plenty of other companies have that grind, and its actually a proprietary grind from a place in texas that has been using it for a couple of years. You can't call dibs on a shelf lobe though, so it isn't considered copying. It sounds like Thunder wanted a traditional split cam to go along with all the others that are out there so they can get there share of the sales. I don't blame um'. I'd like to see them start carrying more traditional splits.

I do not think it is an XE-R. But if someone has the .006 lift number we would know.
Through countless threads it was finally agreed that TR uses proprietary lobes that fall between XE and XE-R.
Why would they change now?

Well, they are 1 degree off from a XE-R. Just enough to call it proprietary I guess. Not sure about the .200's though........

PREDATOR-Z

TR lobes were on the market before Comp XE-R lobes so yes they are proprietary.

TTT nobody running the 230/236 ???

i thought about it, prolly going f13 now though.. there is to much good info about that cam for me to run something unproven.. aren't tr lobes similar to fms lobes.. i heard the f13 is no harder then the tr224 on the springs in a search i did.. dunno if the 230/236 tr is the same way or what.
