Dynamometer Results & Comparisons - EPS 226/234 Cam only

I have an 02 M6 Trans am & I just put in the EPS 226/234 113. After a day at the dyno it put down 376/371. It's about what I expected.

352436

What boltons? auto/man?

Good cam choice. M6?

It says M6 ^^ but I think those are pretty great numbers, I have a 230/238 and really hoping to break 400 with it... we shall see next weekend when it gets dynoed!

Wow I'm blind! :) Same cam here. With bolt ons I hit 401rwh 392rwt before the FAST 92/92, magnaflow & cut-out went on.

I dont think there to bad of numbers at all, good choice on the cam now just get some heads and it will really shine

Time to take it to the track!

i wouldn't call those numbers great. not terrible either. dynos are tuning tools so results aren't worth a ton of effort.

however, it seems to peak early for a 230* cam..

Peak seems early and low numbers. I'm guessing both of those are attributed to lack of headers/exhaust I hope.

What other mods does the car have?

It is a manual, and it has the usual headers and lid. Before the cam I ran a best of 12.69 @ 111mph (with a crappy 60ft), so I'm ready to see what it will do with the cam. I told Geoff at EPS that I wanted an "area under the curve" cam and didn't want to spin real high to get power. I did notice that they only went to 6200 rpm on the dyno, so that coupled with an early torque peak is going to hurt my peak HP numbers. Either way, I like the cam so far and the track will really tell how much I picked up (and now that I will finally be able to go by my buddies Fox body:)

Headers as in LT headers? Mids? Shortys? If you have LT's and a lid, I would say you are down on power. With bolt ons, 4.10's and that same cam, I put down 401rwh.

yeah, they are long tubes. Maybe my tuner isn't that great, not sure why the same cam is lower? Or maybe the dyno's are different? Do you have before/after times for your cam?

Nope. I haven't tracked it yet. I did have UD pulleys which you do not. Other than that, that is it and that wouldn't be a huge difference in HP. Stock exhaust at the time too.

that cam peaks at like 5800...that's not too terribly off from a stock cam. i dunno, i hope it runs better than the dyno shows. if it trapped 111 with a stock cam i'd like to think adding something like that would bump it up to 115 at least.

I think 5800 is really early for a peak too...but tell us how it does on track, you will know if its good or not.

peak looks early to me as well,i would be more concerned with that then the dyno #s..what was the ICL?
was the preload checked?what valvesprings?

This I would start being curious about the icl as well. Turk where is your graph. Maybe it can lead to something if we superimpose it and see if the curve is moved to the left in the graph.

The ICL is 111 and I have the PAC 1518 springs.

The ICL is 111 and I have the PAC 1518 springs.did you check your preload?what's the pushrod length?

Was that verified by decreeing the cam? That's what I was sugggesting

Numbers are low IMO.. Guys with M6 and a 224 cam put numbers in the 380 range.

wow let me tell you guys this. i have the same cam inside my tbss with a LS3 in it with american racing headers and stock heads with a ported intake and made 448 wrhp in a auto with 3200 circle d stall

Captain irrelevant to the rescue! :confused:

Numbers definately seem a little low, but I'm curious as to what it made on that dyno before the cam. Take it to the track and let us know how it does!

its not only about the numbers, so runing on a different dyno or seeing what it runs wouldnt change anything.

i would be concerned about where in the rpm range the cam is peaking.

I have the same cam in my car and put down about 390 with 243s. That was without a lid though.

Hmmm, Pretty Soft down low honestly IMO, i like to see 346's around 190-210rwhp 340+rwtq at 3,000rpm but like everyone else says get some track Times!

that cam is begging for some ported heads.

took it to the track one time on street tires and best et was 12.02 in a full weight truck
