Mods With Stock Tune

[Kimberley Scott]

I cannot understand spending some money and not other money, do it right or not at all. Much rather drive a well maintained safe 255 rwkw tune for X dollars than a 300 rwkw unknown tune for the same bucks.

yes 330kw on stock valve springs

[RAP1D]

Low 300wkws on stock valve springs isnt that uncommon, there's 3 cars I can think of with 330/340 on stock BA springs. they all suffer valve bounce at high rpm, but it depends on how you drive and where you limit the rpm.

Its a good move to do the springs at this level, but not 100% needed.

but chris, surely there would have to be more mods doneto the car - ie exhaust and intake mods, not just a stocker, the standard cat can't flow that much - if mine is at 13psi with 313rwkw, with no cat, how is this possible?

[TOM1111]

I agree with senna

you would have to many more things then just a tune to get 330rwkw

injectors are a must and I would say cat aswell

I've seen cars with high 200's with stock valve springs, but it was only good for maybe 2 runs, then the springs would sh*t themselves, you would have to have a free flowing cooler and exhaust for that much power IMO

I replied in this earlier and still not sure, how a totally stock car, with only the addition of a cooler can change anything.

1. intercooler doesnt gain kw's it gives you the potential to gain more kw's as it has greater potential to reduce heat in the intake which when boost is increased can give more power safer. so everyone sayin coolers gain power are pulling themselves

2. if the intercooler is the only change with the still very restrictive piping how can it overboost as the pipe can only flow so much before its not effiecent which seems as soon as you want to modifiy them, so that's still stock air flow with the cooler

3. boost spike (overboosting) usually only occurs in mechanical boost controller situations as the t pieces by turbosmart are a crappy ball bearing type where adjustment is so dodgy, the boost controller in a falcon is electrically controlled so the spike its capable of is so small it wouldnt change anything.

I have owned a heap of different turbo cars and the biggest way to get a turbo car to spike is the exhaust, apart from the skyline it was externally gated. on the falcon putting an exhaust on the falcon would mean less back pressure which would stuff around on the wastegate hence giving you boost spike and sending the car into its safty mode and retards straight away.'

Without changing anything but a cooler I cant see how any difference would occur as its still flowing through the same as it was with the standard cooler, I only put mine on to deal with the intake heat that would be goin into it during summer not for power gain. it has just made it overall a better car to drive its not as doey in the heat.

no one has really come up with a good argument as to why u cant put just a cooler on it if u use the stock piping just to help with intake temps.

Agent orange, keep in mind that people have gotten close to 300rwkw with the standard pipe work (ie those running the monza cooler) its restricive but its not that restrictive. You might be right about just changing the cooler not effecting the standard tune but at the end of the day most places will do a dyno run for like $50 and all anybody has said is stick it on a dyno just to be sure that it is still safe... that $50 is cheap insurance

I am running 330rwkw @ 16psi on stock BA valve springs .. mind you they are about to be replaced because I know they are at there limits .. and they dont bounce

[AGENT ORANGE]

O im not sayin dont stick it on the dyno at all, just I cant see how it would make like earth moving change only placing a cooler on the car.

im not starting anythin just talking from what I have owned and how they have reacted to mods. ill be gettin mine tuned early next year I cant wait

Yes mate I was just talking about valve springs in relation the power... those cars all had exhausts, intakes coolers ect done to support the kws.
