How do I get past the wall at 5000 RPM!

[9 Deuce GT]

First let me start off by saying that I have never taken this car to the dyno or track, so I have no substantial proof to back up my situation other than the SOTP meter.

I like the combo that I have now. The low end is great, and it pulls hard up to about 5000 RPM. I knew going in that the pull would level off around that RPM. I thought that RPM would be fine being a street car, because I didn't think that I would be spinning it that high that much. But since I've have had this combo for a little while, I think I am getting used to it. I also like to stomp on it every time I drive it now. I would like to get it to pull hard to 6000 RPM. I suspect the intake to be the culprit. I have heard the Cobra is notorious for dying in the upper RPM's. Is there any thing I can do without changing the intake to something bigger?

My combo:

Cobra intake, TMOSS ported lower
AFR 165's
1.6 RR
TFS Stage 1 cam
80mm maf
65mm TB
1 5/8" eaqual length MACs
O/R H pipe
2 chamber flowmasters
U/D pulleys
30# injectors
3:73's

That's all I can think of right now for engine mods.

What do you guy's think. Is there anything that I can do? Is the cam causing some issues?

I'd say your issues are not in your combo, but somewhere else, seeing how stockers pull fine to 5500.

its in the cobra intake and the stage 1 cam, They are designed for low end grunt.

i'd say with a good holley or rpm2 and at least a stage 2 trickflow you would feel a good improvement

oh didn't see the cobra was ported bytmoss, I'd say definately go with a more aggressive cam if you want more top end.
