Pushrods are being measured right now, good thing is if its doesnt make power we can blame the guy who speced the cam
..LMAO!

Haha, this is his most retarded thread to date. He changed the cam, converter, MAF and fixed a signal problem by replacing a bunch of stuff. You could have lost power from the cam and gained enough from the other things to show the same results. That's not necessarily the case, but you can't rule it out.
lighter and smaller to heavier and larger converter swap... it would have made more power with the neil chance 8 inch converter in it.
Maf worked fine... the old one blew up due to the signal loss problem. The problem started happening recently... it was fine months ago.. I have tens of dozens of timeslips to prove it.
this is 100% a gain from the cam change.
The old cam fell on its face up top but like they said would be good down low... the new cam was better in both areas.

Doesn't really matter as long as there's a gain, I guess. What's this cam do on the nitrous?

Track times willtell the tale. I would have took it to the track before I posted anything. Then you wouldnt have to here any crap. But then again you changed some significant **** that could affect power one way or the other. Meaning the cam could have given you more of a gain than the dyno sheet is showing. Track times, Track times, Track times. That all that really matters in the end.
The converter could definitely effect track times more than 20 peak rwhp. Still would prove little about the cam.

Haven't sprayed the car yet..... still needs an alignment to go racing.

....moral of the story...
Go with someone who is forthcoming with information on the parts they are trying to sell you and who is established and trusted in this industry.
I can think of no better company than TSP for this.
Those who are hiding specs and information and do not have the reputation want to lead you to believe they know something that other companies don't. This makes me laugh....

Track times matter most..... regardless the bigger cam with a larger split didnt lose power... I swapped from an Art Carr to a Neil Chance converter both around 3400 stall and they didnt make that huge a difference in upper end horsepower. It is not like the converter swap is going to gain 23rwhp IMO. If it does than the cam change was still an improvement because a 236/236 wont perform on the bottle as well as a 236/248

Everyone claims to know about L92 cams, but there really aren't many people that show and supply good, concrete evidence as proof.
My question is, who is the MOST knowledgable when it comes to GOOD L92 cam/engine combinations???
Everyone builds engines differently as far as combinations go. Bottom line, if you race, you want the most from your engine in your driving rpm range. If you build a DD you want the most from your combo in your driving range. It's a touchy subject with a lot of self-proclaimed pros and specialists. Dyno figures and track times point out the best combos for any particular set-up IMO.

Converter WEIGHT is not the only thing that changes it's performance. There is a reason a converter change from one converter to another with the same stall can MPH better at the track.
Not saying the cam change didn't help but you have no clue that it did or didn't in reality.
In terms of SECRECT cam specs.... who cares. Some of the best running L92 combinations out there the numbers are not public knowledge because there are so many know nothing cam spec pirates who "learn" I mean copy them.

That VERY EASILY could be the difference in the RWHP numbers.... don't discount that fact. Any driveline change, especially a CONVERTER in a automatic has a big effect on the power at the tires.

J/K, excellent point. Both on account of the converter change, as well as secret cam specs.
It's just like tuning secrets, the good ones aren't just thrown around for free.

FWIW...
I really don't see how you could chalk it up to just a cam swap netting the power gains. Nor am I sold that a big split is the way to go.
I have a stock LS2 bottom end, stock L92 heads, stalled A4 and make 450rwhp in an 05 GTO. with a 232/236 600/600 113lsa cam.
Just don't think if I were to put your cam in I would magically go to 473rwhp.

I believe the dyno numbers where after the converter swap... I need to look at the dates and look at what files are on the shop computer by the dynojet to confirm.
It seems that everything just runs together now, and with the last few weeks of personal problems I cant remember ****. (my mom passed away). Give me some time to confirm this with the guys at the shop. I have had the converter for awhile and I think they dyno'd the car with the new converter on the spray. I need to look at the date of the nitrous dyno and see the bill on the converter swap.
