Well tuned my fully built 84.5mm sleeved Gsr motor with a full valvetrain done up with stainless valves dual springs and titanium retainers victor x manifold port match to a 76mm throttle body 3inch boost piping and a full race divided top mount turbo manifold and dual 44mm wastegates 4inch exhaust the turbo has a 1.06 turbine the car made 376.9hp with 289.9lbs tq on 15psi on pump gas power ran out due to cams. I think the number's are not very great for what i have done to the motor I was wondering if switching to ctr cams might help or would it what is the max boost some of you guys are running on pump gas the motor is built for high boost so yes I know little low boost for a gt4088r kinda figured that might be why its not putting the numbers I thought it would on 15psi please no clowning just need some advice

 

somethings definitely holding it back. I've made more power than that on stock b16 cams. the tune maybe?

the setup looks solid on paper, but without a good tune well...

 

really I think it might be in the rich side timing hasen't been played with at all except whats needed motor only has 550miles on it been working our way up whats some max boost levels on pump gas

 

that motor should be making over 400, tq looks pretty good

 

I definately know its not the cams. GSR cams can easily make 500+whp. but there are many variables and its always hard to compare numbers. What kind of dyno? intercooler? and turn up the boost with some race gas. how capable is your tuner?

what about switching to ctr cams

 

the cams are fine, no need to switch, could be just the tuner

 

really I guess you can't tell me anything without seeing the tune but I will deffenetly look into it thanks

 

Iam running EMS stigger 4 management system full standalone system

 

ive made over 600+ with the gsr cams i would look elsewhere. do you have a dyno graph to look at?

 

I will get one up on here tomarrow or sooner thanks

 

anyone have a setup close to this that i can show my tunner any dyno charts max boosting on pump gas

 

has anyone tried CTR cams

 

many have used ctr cams. i am going to in my future setup. but first find out whats going on with your current setup because as people have said, its not the cams holding your power back... its something else. good luck and post back whenever you find out!

 

I KNOW WHATS UP ITS IN THE TUNNING KINDA NEED TO RE TUNE NOW THAT ITS ALL BROKE IN PLAY WITH TIMING AND ADJUST SOME FUEL ITS RUNNING PRETTY RICH IN AREAS WILL SEE GET BACK WITH YOU.........JOSH

 

whats some max boost some have seen on 92octane fuel

 

Car we tuned Friday with a setup very similar to your's. Only difference is stock throttle body, CTR cams, full 3" CRX exhaust, AEM EMS, NAPA distributor (changing) and 11lbs creeping to 12.8lbs/13lbs

 

something is def. wrong with your car. either the tune or something else. with that setup, 15psi should be netting u around 450whp! i was making 370whp on 10 psi with a GT3582R on a 81mm LS/VTEC. u have n e dyno graphs to post up?

 

Hey alpha, do you have any graphs of that vs rpm? The spool doesnt look that bad at all.

 

my first guess would be that vtec isnt working. if that 289ft lbs were at 9000rpm, or even 8500 then you would have 470+whp.

without a dyno graph its tough to say though.

Thats what I made with a 84.5 mm LS vtec but ctr cams and 70mm TB divided mani and 1 tial 44mm WG tunned on E85. Maybe the vtec wasn't engaging like some one stated.

Sorry. I don't. We were having issues with the pickup, distributor and dyno stacks that day. If I remember correctly 85MPH is about 5400RPM - 5500RPM

 

Oh yeah, what gear is that? I could have figured it out. Lol.

 

It was fourth gear
