Numbers look solid!!! add thoose last few boltons and 400+ is in your future.

thanks man! and thanks to mike for the help and sam at fairway for tuning!

Do you have LS6 intake ?? Numbers are seems a little low since the graph is STD.
with your setup I believe 410-420rwhp SAE will be more like it.

TQ curve looks good, but considering those #'s aren't even SAE corrected you're about 40HP down from where a cammed/243 setup should be.

If you enjoy it that's all that matter I guess.

i agree also. I do not think he has an LS6 intake, and those 243 heads arent ported. but usually M6 with the TR230 with stock LS1 heads make 390+rwhp cam only.


Casey, slap a fast 92/92 and see how much more it picks up.

Wouldn't 7.4 pushrods be too long with milled heads?

My cam is similar and only made 350 unlocked (figure 370 locked) with ls1 heads so he might not be that far off...especially if he has a ls1 intake choking it down.

Horrible advice. The valve events of a TR230 are NOT designed for high flowing intakes. That cam was designed for one purpose, which hasn't really been necessary in almost 10 years now.

Not if you're using an aftermarket camshaft with a smaller base circle.

I was just curious because I was advised to use 7.4 pushrods with stock heads.

Could you elaborate on the FAST intake vs tr230 issue? I only ended up with a fast because it was an awesome deal at the time ($500) and I was getting a ls6 anyway.

Are you just referring how the cam favors a high flowing exhaust and increases intake to handicap poor flowing intake designs?

That's the numbers I expected...I think SAE it was 387rwhp 370rw trq

The graph looks pretty healthy, what do you think could be holding it back from making the right power?

Also, I DO have an ls6 intake..I forgot to add that to the list. Every dyno is different..that may have something to do with it.

I wouldn't worry until you at least run at the track, mine made "low" power but I sure as hell cannot find anything wrong at all...only thing I haven't looked at is actually getting a tool and measuring for pushrods to see if my 7.4s are correct.

caseypryan

Yeah I enjoy, but I obviously want my set up optimized..this build was based on a daily driver with full driveability that would make good torque. And you can't really say 40hp down from where cammed/243 setup should be...there are so many different cams out there that make very different power. And this is basically a baby-mild cam. and these 243's bone stock except a slight mill.
My buddy here in town has a G5X4 and stock 243's and made 404rwhp through an auto. So for the general area I'd say this power is pretty good..

My numbers were pretty much spot on with what I expected but maybe since I'm not completely full bolt on and have 4.10's they weren't quite as high? Also I have a heavy LS7 clutch which sucks up some power.

caseypryan

Well if the push rods were too long you would see valve float and a wobbly dyno graph especially in the high rpms.

I'll see what it does at the track because dyno numbers don't mean much.

Also this dyno was in vegas so the DA is pretty high.

Between the gears and LS7 clutch,those take a good amount out of the dyno #'s. The pushrods could very well be wrong,can't tell without checking the preload.

40hp more with that setup? No way on my dyno.

I'd have to disagree with you there Damian, stock head/cam ls1's were picking up 10-15rwhp with just swapping to the 90/90 setup. Im not saying its a justifyable upgrade, but its definetly not going to hinder him from making more power.

thunderstruck507

iTrader: (18)

I picked up right around 25rwhp above 4k (based on dyno and traps) from ls1 to my lightly ported fast 90/90.

My cam is a comp grind with the same duration, lift, and 111 lsa but it is on comp lobes and has 3* ground in.

We aren't discussing track results....D/A doesnt mean squat on the engine dyno because the weather station / correction factor will take the quality of the air into account. Thats the entire reason weather stations and correction factors exist allowing results all across the country to be compared regardless of air quality at the time of the testing. If you test in a really cool climate the correction factor actually hurts your numbers!

Also, Im surprised no one touched on the fact a reverse pattern cam with a weak stock exhaust port is also costing the OP some power (thats not what I would have spec'ed).

Drop a 230/236 in that engine and I bet the peak numbers look a good bit better.

The LS7 clutch isnt helping either which has already been touched on....

Get it to the track and see what it traps....that will let you know how stingy or generous the dyno may have been also.

If you trap a big number then you know the dyno may have read a bit on the stingy side.....some of them do.

You could also ask the shop what they typically see from stock vehicles that we can all relate to get a better idea of the type of numbers it spits out (A C6Z06....a C5ZO6....even a stock LS1 car, etc.).

Good luck....

I would have expected 410-415rwhp out of that setup. TR230 is usually 390-400rwhp and stock 243 heads are worth 15ish, from what Ive read.

check this TR230/243 setup out:

ive seen MTI throw a reverse split with a fast 90/90 and it still made power.

Nobody said a FAST intake won't "make" power. But this whole internet phenomenon of "just throw a FAST on it" every time a car posts up sub-par #'s is a crock. That seems to be the only mindless solution these internet mechanics can come up with these days....."Hey man, your #'s are low. Just go spend $1000+ on an intake".

How about optimizing the combination? Thanks to the internet, this philosophy has pretty much become extinct.

FWIW, the TR230 was developed 10 years ago as a way to crutch the engine for the lack of intake flow we suffered w/ the LS1 intakes (before LS6 intakes were readily accessible). The valve events are not designed for a ton of air flowing through the intake. It's the opposite, actually. Thanks to TR's marketing team over the years, this cam has been splattered on the internet as a great way to make power with any combination. However that isn't the case. It's a great way to make power if you don't have a good intake. If you've got an LS6 intake (or better), there are much better cams out there.
