what do you mean "should pull 170, 180kw with new computer"?

go to jim mocks dyno and you will have that figure.

maybe convert to manual, or run a high stall in your auto, or fit some semi slicks for the run if traction is an issue.

id look closer at the tune cos it should be capable of mid 13s, are you having problems with the launch?

Mid 13's big ask from an auto EL....

dev5 is a large cam maybe the stock Head (no porting) is restricting the Cam's flow at high lift.

also did u get a before and after dyno readout with the Chiptorque chip ?

What was you 60 ft time? And MPH ?

You may find you might be missing in an area and gaining in others.


I think the stall might be part of the problem, perhaps either launching not well enough or even too well.

You should be able to get the 60ft time to about 2.1-2.3 and the trap speed to be around 160km/hr+.

if i stall the car up traction is an issue but if i jus sit there n punch it off the line its not too bad. 60ft time is about 2.3 secs n ova the line is high 140s or 150km/h. all the rocker gear has been rebuilt to suit the cam but the head is still fairly standard, i dunno how much its restricting me but i was still hoping for a mid 14 atleast. the car isnt running how it should ill try n get a dyno run in during the week n c what happens.

That 60ft time is really slow for that set-up. I'd be really working on those launches to drop that 2.3sec down to at least a 2.1sec 60ft. Old saying goes, "Drop 0.1 off your 60ft, it'll drop 0.2 off your ET". So in saying that, if you could drop your 60ft down to 2.1 that'd bring your ET down to 14.4, which i'd say would be about right with that MPH your pulling over the line.

try less tyre pressue and check your rear shocks, seems like your not getting a lot of weight transfer happening.

it could be the weight holding the car back, how much do you think the the tow pack and sub box weigh? it only costs a few dollars to put it on a weigh bridge then calculate your power to weight ratio from there.

as far as good weight transfer goes i reckon hard shocks and neoprene (black) bushes on the rear will make a huge improvment with the eta.

this is an old article now, but it shows what the NA is capable of with the right setup.

im runnin 15" stokies n ova line im in third n about 4000rpm i think. ive been drivin all day 2day n its been surging abit n i think its a s**t tune on the chip. the only difference i noticed was no speed limit. it feels like the car runs worse with the chip than it did b4.

Got a similar setup to yourself apart from the chip torque chip! That thing should pump along better than that! I would be expecting 14's at least!
