TR 230 Cam Questions
Thats alot of cam he is talking about for a daily driver stock displacement LS1.
Do you think we have finally reached the point of diminishing returns on these big cams? The cams here have been getting more aggressive for quite some time now. Have we reached the limit for a [non-race] car?
Just a thought....
Ron,
ie: over-carbing
ie: Holley Dominator 1250 carb sitting on top of a low compression, mildly ported, stock displacement, daily driver SB Chev engine. Result; Poor throttle tip-in, poor driveability, lost of power/torque, horrible gas mileage.
I certainly understand the need for speed, but, it comes to a point where you can only use so much cam / carb / etc for a givin displacement in a [street] motor.

I went from the 224 114lsa cam to the 230 reverse split and picked up right at 10rwhp, with no other changes. I then removed the y-pipe and ran open headers and saw an additional 10rwhp.
There is more potential with the TR230 as long as your car is tuned correctly (which goes for any cam) and have a very good exhaust system.
Ron, my car is a daily driver and I really cannot tell much, if any difference between the 224 and the 230 reverse split in terms of driveability. The 230 does have a more distinct lope at idle. I am still using the stock idle speed (with TB drilled out) and the car has zero idle problems.
Again, if you are in doubt, the TR224 is a proven winner. You cannot go wrong with it. If you do want a little more, then look into the TR230.

Ron,</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">We will reach the limit when increasing the cam size fails to make more power. In Jason's case, he gained 10 rwhp over the mighty TR224, so obviously this is not the case. I daily drive a cam with more than 230 intake duration and less than a 111 lsa; it hunts for an idle while I dig around for my sunglasses and find the radio station i want, then its good to go. I got 25 mpg on a recent trip from Dallas to Houston averaging 85 mph, not too bad eh?

<strong>My SS is my sole mode of transportation. I drive at least 300 miles a week. Driveability and fuel consumption are big hot buttons for me...as are maximum hp and tq under the curve. The 230/224 reverse split cam picked up power above 5000 rpms and lost nothing below while maintaining comparable driveability and gas mileage compared to my TR224/224 cam. Gaining ET and mph without losing street manners is a winning combination if you ask me.</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">You have a 230 duration 111lsa cam in an A4 and the thing idles fine? <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Damn...I've been outta the game too long.

<strong>Hrm, I'd try one if I wasn't so worried about P/V clearance on my intake. I have 2.08" intake valves and 0.030" milled heads.
