I miss Rockingham. I used to consistently trap 2-3mph higher there than in Jacksonville, yet I could never hook. I consistently rattlesnaked my way to a 4-wheel burning 1.7x 60' each time as compared to my consistent 1.6x 60's in Jax. Strangely, though, I'd get the same ETs at each, so I guess it all evened out.

Rockingham best - 12.110@113.6
Jacksonville best - 12.112@110.1

 

It was stock when i did 11.6@117.44 now i have springs and retainers!

 

Jus a quick question for you guys ( and gals!) - When you quote 'whp' do you mean flywheel of at the wheels?

 

Uh, the "w" stands for "wheel." If we just said HP, then the question would have merit, but since we say "whp," it automatically means "wheel horsepower." You may also see "bhp," which is "brake horsepower," but that would be flywheel.

 

Hmmm.... Does the air in the US have some kind of 'additive' thats absent here in the UK. You guys quote VERY high figures for essentially what is a 'stock' engine? As far as i'm aware we both use the 4G63 core - can't really get my head around it??? Hence my question.

 

The 4g63 is capable of this hp easily, so that isn't in question. The problem is claiming 469 on the stock engine AND turbo. We disproved the 469, but his 432 seems to be valid. This is tough, but doable on the stock turbo. It's completely doable on the stock engine with head upgrades.

 

I agree - I have seen a 900+ hp 4G63 BUT it is extremly modified and no way a'road' car. I can not even believe 432 at the WHEELS! On std internals and std Turbo, you can't really tell me that you are going to see a 'reliable' 350hp+ ATW figure???
Here's a scenario, below i have listed some mods - please tell me in your prof. opinion what figures you would expect - assuming the engine was mapped/fueled correctly with NO det.

Piper cams (285)
Blitz I/C with hard pipe kit
Blitz ind/Exhaust and De-cat
Blitz VTA DV
Sard Reg
1000cc inj's
Walbro FP
Custom fuel rail and lines
Mappable ECU Autronics/Motec/Gems
Equal length SS Exh man.

What do you think then?

 

don't those piper cams have high lift? 285 duration...wow...i don't see those being optimal for the stock turbo. i think on a dynojet or this high reading mustang you'd be at 400 or more.

what kind of 1/4's have you put on those kinda mods? are those in your evo6?

 

hmmm... maybe I should strip off all my mods and down-tune and go for the LOWEST WHP, stock turbo Evo 8.... seems easier than trying to win the highest whp, stock turbo Evo 8! LOL

 

I was at Aercomp about 2 weeks ago chekcing out some EVO's that were being tuned. That dyno is definitely miscalibrated. Evos on pump gas with mods were making 370-390whp. NO WAY that is correct and these were 3rd. gear pulls.

 

Holy fueling! 1000cc. I believe BoostedJoe was running 660's or 680's. You must need a ton of fuel in the UK, unless you have BIG turbo plans in the future. I hope you mean Blitz intake also. Joe uses stock exhaust manifold, stock ECU remapped, but c16.

 

The inj. duty cycle is not at 100% for obvious reasons - I wanted my fueling to be 'extra safe'! , and be able to cope with future mods. As you are probably aware you can adjust the fueling etc etc on a mappable ECU - so there for the car is going to be tuned as good as the guy who maps it - now I could have my car mapped at 2bar boost and have loads of det etc - that would push the bhp/torque figs up - but would it be reliable and how long would my engine last???

Why are UK vs US figs so far apart - particularly when we have similar mods? The kind of whp you guys talk about are on cars with at the very least forged ints and big turbo's etc??? ...............BUT there again they are reliable cars.

 

So come on guys - what do you think? BHP/tor..... figures that you would expect in the US....

 

Not all US cars are like this. This is with C16 race gas, not regular pump gas, too. The guys in Orlando are expert tuners and drivers, so the make more power than most on average. At the same time, that dyno is believed to read higher than normal, too.

 

I love pissing contests!!!!
