Baseline 207 WHP. Not sure what type of dyno.

Now basic built block, making 450WHP on 14 PSI. People on this forum seem to be making much more power than this on this boost level. Is there something wrong with my engine?

 

Making a Guess here but it might be the Dyno itself.

 

what dyno are you using? Baseline seems really low. Can you post your dyno graph?

 

More info ??? FI kit, exhaust, HFC's ? need info

 

We need details!!!!

 

Basic built block.

ARIAS ED Pistons 9.0:1
Eagle Rods
ARP Bolts
HKS Head Gasket
Cosworth Bearings
Valve springs and shim kit
Stock APS TT kit except for upgraded actuators (unichip, fuel system, etc)

I think that's it engine wise.

I'm not so concerned with the actual numbers as I know different dynos produce different numbers. I'm interested in the increase over stock levels.

So I've gone from 207 to 450 WHP on 14 PSI. This is an increase of 243 WHP - does this seem right?

 

seems a little low. What engine management and exhaust are you using?

 

Well from the 207 I would say it is a load based dyno so 450 is not bad it would be around 500RWHP on a dynojet, maybe a little low but not by much.

 

Engine Management - Unichip

Exhaust - APS True Dual 2.5 inch

 

You still havent answered, what dyno is this on?

 

Agreed, REALLY low baseline.

 

Do you still have your cats installed?

 

seams real low

 

It's probably kW not HP, the guy's an Aussie, explains the 207# baseline

by the same logic 450kW > 450hp, so maybe the car is fine

 

If it was really kW, that would be around 600 hp. that's too high.

 

I have read somewhere australian dynos read lower.

 

Dyno Dynamics - which is load based I believe

Those figures are in HP

Other things: high flow cats, APS Plenum

Whatever dyno you use shouldn't the increase in WHP be approximately the same?

So does a 243 WHP increase seem low to you guys?

 

It's a little low. Most guys here dyno around 230-240whp, so that comes to about ~490 whp with your increase.

 

Considering you are running cats, and stock heads, your numbers aren't terribly low - especially when you factor in your baseline.

I know aussi land has some killer unichip tuners, but IMHO you are beyond what the unichip can do for you... it 'may' be holding you back.

One other thing that came to mind is your fuel system. if you are running the out of box APS fuel system, you have all but maxed out those injectors and that also may be limiting your HP.

 

thats what I was thinking.
