Can anyone post some dyno graphs of FI cars making power over 6700RPM? Please list the mods done to the motor. Thanks!

JET

 

Yeah this would be great to see Im wondering how to get my 3.5 maxima engine to make power over 6000!

 

+1. I would like to see one as well. I am hoping my car will make power above 6700, once it is completed. I have a cams, port work, and a built bottom in.

Thanks

 

Making power above 6k rpms is going to be dependent on multiple factors including boost. Higher boost is tougher due to flow limitations - so not sure how helpful that link is (because it shows only a 6 and 8 psi curve). I'm having trouble finding JT's experiment with cutting all the runners off the stock lower plenum - that should've shifted the torque curve way to the right. Anyone recall this or got a link?

 

SFR TT kit w/ non ball bearing t3/t4 60-1 hifi's
Tial 38mm wastegates w/ dump tubes
2.5 inch down pipes
HKS knock off exhaust
AAM plenum spacer
Utec w/ map selector switch and map sensor
RC 440 cc injectors
HKS EVC 6 boost controller
Innovative wideband 02 guage
HKS SSQV BOV
CJM fuel return kit
Walboro pump

 

It's been my understanding that the lower plenum from RevUps will allow power to be acieved all the way to 7k.

I plan on bringing my polished MREV2 and stock lower plenum to PF when I go down there.

 

They help some from 6000-6500+ but not enough IMO to warrant the TQ drop and weak midrange it provides. I tried this years ago in my stock block set-up and made bad peak numbers even. IMO its a BS mod but I know Jet wont agree because he has it.

Jet-look for Forefedz's dyno making power to at least 7000rpm (he revs to 8300rpm's) with BC stage 2 cams, stock heads otherwise.

This is a G35 I tuned with F-Con V pro...

575rwhp/Mustang Dyno...
Greddy TT kit...
JWT cams...
Upper plenum..
17psi

 

If you can rev that high just by switching out cams and the other head components, that is definitely something to look at that is dirty.

 

i saw this too

 

+1 on all


point to BC stg2 cams

 

In time I will have results on some new things

 

BC 264's with head porting and +1 valves: (BC cams in stock! 3 sets of heads are in the works right now)

Revup lower(red) vs Cosworth plenum(blue):

 

Hal,

do you guys change out the valve seats on the heads you do? My head man recommended to not go with oversize valves on my heads. He said that there just isn't room on the stock seat to accomodate them and I wouldn't gain any flow unless going to a larger seat. What do you usually do?

Isn't that Mike's car? Does he still have his custom plenum and front facing throttle body?

 

...Yes it is Mike's car... and yes he still has the plenum and TB......he does AWESOME fab work!!

 

we have a few cars that pull all the way up. there are soooo many variables to the equation.
