He has an LS6 intake already...

Jermzz and I put the cam in, as well as the other mods, the car runs great, all the way up to 6800 on the dyno.

#'s are low...theres no question, the pulley should be putting him at 405 up from 400, not to 390.

This was on a dynojet...and the same exact dyno my car was tuned on.

He needs to post up the graph, but the A/F was straight across from what i remember, 3rd pull it was 12.6 to 1, on the 4th run it was 13 to 1...he put it back to 12.6 to 1, there was no difference so they left it at that. I was hoping they'd try another run or two but they assured us it was maxed out.

As for timing, i believe he said 27 degrees...

The guy said the intake seemed restrictive, but he has a lid, and an ls6 manifold is more than good enough for a cammed car.

Anyone have any ideas?

Same tuner just did your car with same mods but a smaller cam to 409.

We installed both cams too. Not that it matters, you put it in right, or you dont. haha.

Deeerrruugghhh. Maybe next time I'll read his sig. Even still, removing the EGR, and adding a pully and TB will help alot. If he made over 400 he'd be in line with other cam only cars. Even though the cam is named the "Magic Stick" it's still just a cam. Nothing truly magical unless ya'll got the gold one with pixie dust and little faries in the box.

haha... im sorry, but i knew what your first line was going to be when i saw the title of the thread... my friend and i belive that the cam is overrated...

300bhp/ton

Any particular reason?

I guess probably not juging that you believe TB porting is negative to performance and the other contrived you've been posting in the External Engine forum.

There advice on a bolt on LS1:

An MS4 has close to the same overlap as a T-Rex. My experience tells me that neither of those cam will tolerate any back-pressure in the exhaust. They are extremely sensitive to it. I've seen dyno graphs where a T-Rex car picked up 40 rwhp by removing the cats.

Some cams like the CheaTR are very insensitive to back-pressure, but cams like the MS4 and T-Rex are VERY sensitive to it. Bottom line, remove the cats, re-tune and find your missing horsepower. 385rwhp is pathetic with a cam that size. You basically got all the bad with none of the good.

welcome, this is the first time ive ever seen you in the internal engine, hope you learn some valueable information

i respect those who respect me and those who know what they are talking about and arent ****** for no reason.

The cam does need to breathe better with a higher volume intake manifold. Honestly though, you should not expect anything way over 400. You will need heads to break well over the 400 mark.

Be more concerned with how the car runs, try not to get obessed with #'s.

Remove Cats and get the pulley and you will see 400hp. You might want them to play around with your A/F ratio somemore. Mine is between 13.0 and 13.5:1 and i made 410rwhp with a MS3 through a 9in rearend.

i would listen to patrick on this. i have seen other posts and cats turned out to be the problem for those cars. even high flow cats can hurt your numbers.

heres the graph

shouldnt that cam keep pulling to like 7k?

Dub C

Its 111lsa... its suppose to make peak power earlier. When TSP tested it on their dyno it made peak power at 6400rpms.

Nevermind... i just saw that he has the 112lsa... either way it should peak out decently early in the rpms.

Yeah, if you've got the bolt-ons for it. TSP said that it should peak at 6800. Mine started to taper off after 6k (took it to 6.5k) but did not by any means drop off sharply. Definitely starving for air at that point, but the motor is stock from air filter to exhaust ports on the heads so I'd say it is performing pretty well on my car. It pegged the butt dyno the first time I drove it

Should have had your car dynoed prior to the cam install. With my car, it put down 300 rwhp with mac mids and a catted y-pipe through an SLP LM, with the 232/238 cam in my sig, gutted cats, ls6 intake, prted TB, and pulley I put down 370 rwhp. Thats a gain of 70 rwhp, which is pretty damn good. My heads are the limiting factor though, and im sure your 99 heads are the same problem. As everyone else said gut the cats, get a ported TB, and a pulley and retune and you should see 400+ rwhp. Good luck though and let us know how it turns out!

did the 99's get the 853 heads? if so, . there is your answer, . . and i think those numbers are low too

eamador11

why didnt you put a pulley when you did the cam? thats free labor for the pulley

I'd say pull the cam and degree it. Just because you lined it up DOT to DOT doesn't mean it wasn't accidentally misground and is off a tooth or two.

I agree with 300bhp, Cop car. You have no business posting tech information. You're not very informative based off of your posts AT ALL and you make the most asinine comments I've ever seen. Porting a throttle body = bad ? So.... you're telling me more AIR FLOW = less power ? OKAY...I think you have that confused with porting the MASS AIR FLOW, which is what hurts power and tuners HATE because it is such a bitch to tune with.

MS4 overrated ? Not quite. It has been PROVEN that this cam has fantastic valve events in order to make some decent low-end torque for the size it is and proven to make killer mid-range and top end. You want a cam that is over rated, look at the MS3 or the HPE S-cam. Two HUGE cams with ridiculously wide LSA's which is the complete opposite of what is necessary for a stock cube motor(which these cams were ground/developed for) but yet EVERYONE and the frickin mother praise these cams because of their PEAK POWER.

the cats are definately hurting him, but not as much as those would expect. to my calc this cam only has 16.5* of overlap, to the compared t-rex @ 25*...big difference. i doubt much if any gain will be seen on stock heads with this cam vs. the ms3. these engines aren't very consistent in terms of performance. the same cam in different cars often yields widely varying results. the biggest improvement they could've done to the ms3 was put it in a 110 lsa. it seems that most ppl who have commented on the ms4 thus far are praising it and expecting it to whip the ms3's ***...when it reality, it won't with stock heads. ms4 is a step in the right direction for our 346s, but, i agree with cop car that it is overrated.
