Ive been hearing and reading stories of cam only cars hitting tens. how in gods name is this possible. death valley, 70 degrees, and 10 year old girl driving?

 

T-rex cam, stock heads, bolt ons, bad-*** tune, 12bolt, slicks, 4500 stall

and practice

seems like they were in the mid to high 10s with that setup....

daily drivable...nope

 

Good Call. I hoped drivable.

 

cam only...no way

least not by normal "daily drivably" definitions.

mid to low 11s are possible with a car that can be driven in rush hour traffic...but not 10s...i don't think

 

That would be nice.

 

The record for stock internals/ stock cam is actually in the 10s. Race weight was the biggest contributing factor in addition to every possible bolt-on.

Depending on if you want creature comforts (besides just a light weight race seat) and good drivability then the 10s with just a cam quickly get harder to run.

I'm sure that "10 second bolt-on LS1" car isn't too much fun to drive on the street to the park on a Saturday afternoon.

I'd go with the TRex as it was designed as a max effort stock CID camshaft.

not much has been talked about on the Trex in a while

i'd be looking more towards the FMS RJ cam....it's made almost 415 to the wheels on Kraests car....through a vette drivetrain

 

Rodney's car (the cam-only LS1 record holder) is a local guy who's car is basically a trailer queen ever since he put the big gears and pro-shifted T-56 (removed 5th and 6th gears) and lightened it. That car is INSANE, but is basically a racecar.... Pretty much a step down from a stock eliminator car. I think the best he's gone cam-only (still has stock rockers and TB) is around 10.2X@ 130ish. I think the previous best when he still drove the car on the street non-proshifted was more like mid-10s....still VERY impressive.

My car did that also with a stock unported TB and no underdrive crank pulley, which together is worth at LEAST another 10 rwhp. I think the car could have put down 430 had I installed all of the bolt-ons on it.

My buddy has the F-14 and put down 423/408 with his Z06.

To answer the original post:

It's possible if you use a huge cam, tune the **** out of your car, lighten it, and put slicks on it....However, a 240+ duration .610+ lift cam on a 110LSA, 4800+ stall + 4.56 gears would aggravate some people, as would leaving at the limiter with a 6-speed... Gas mileage would suck, driveability with a cam that big sucks, etc.

 

yeah i think magnus' car was in the 2700lb range had a 5000+ converter & put down like 430 to the wheels through either a 12 bolt or a 9in...definitly not streetable.
