Do you even know what point your trying to make? Or which one of mine you were trying to debate?

I never said his car would be slow. I was speaking in terms of dyno #'s only. Also, if you'd read the thread in it's entirety, you would have seen my latest reply telling the OP not to worry about the dyno #'s because his track results were great.

Run along now...

So what is your opinion of the performance? Good air will give you a ET reduction of approximately .3. You should be pushing that 10.9x real soon.

Weight is what is killing me. I am still trying to get the graph from Fran and will post it so the picture is clear. I think it did real well and know the air sucked! We are putting stock rockers back on this weekend and I will hit it again next Saturday on test and tune when they prep the track better. It might have an 11.1@120 in it.

Here is the graph:

Interesting dip after 5700, then it seems to start mnaking power again.

Letting off the gas? Don't know on that one.

It almost seems like the pedal might have been lifted just for a split second....I mean it only drops for 200 rpm or so, it would be nice if there were more then one run.....can you get any more graphs or is this the only run that was made?

Well I did a search and found a post similar. At the bottom is a link to another post where they saw a similar problem:

Interesting read, whats your lift on the 1.7 ratio rockers and whats it come out on the 1.85 ratio rockers, if I'm correct in remembering if that is what you have.

.534/.537 with 1.7's
.584/.586 with 1.85's

What lobes does that cam use? That seems like less lift for the duration than an XE lobe.

Subscribed. I am looking at running the Mamo 224/228 and want to know potential problems.

I think he was making a comment that you said that cam was dated technology but then the car ran mid 11's. That's just a guess. I don't have a dog in this fight. Maybe he will reply.

Well we switched to the stock 1.7's today and the car started hitting the rev-limiter like butter.

It's making power past 6200 now. I think it does have an 11.20 over 120 MPH now in it.

Very weird it never hit the rev-limiter on the 11.46 pass. Today it was hitting it good so something has changed.

I can't wait to see track times with your setup now that it's supposedly fixed. Nice...

Are the heads the LS6 Patriots? If so, what size chambers? I forgot if that was posted, sorry.

I get a little sewing machine noise so I am ordering longer pushrods then it will be 100%.

I would have ran it today but the track was just too packed. Next Saturday I am going again. I think it will go 11.20@120 but who knows.

Where you getting coil bind with the 1.85 rockers? I am asking because I am trying to figure out why they hurt your power so bad. Where they making your valvetrain unstable?

Intercooler2

iTrader: (24)

No coil bind. In this case it is valve float at upper RPM's. Who knows maybe it is early on too just hard to see.
