i want 2 pull 145RWKW

[E-T-H-A-N]

i have a vp calais 3.8l v6. i have pacemaker extractors, 2.5inch catback and ss cold air induction. i want 145RWKW what do you guys sugest 2 get 2 that ? im already getting injectors and a comp cam is high on the list. forced induction is also an option.


any ideas ?

[Zuicider]

what comp cam? will lose alot of the cam if u dont get sum heads

[E-T-H-A-N]

the 1 i want requires headers and exhaust kit. no head work

[Zuicider]

thats a small cam, oh well just et a tune after the cam, if its not too small and u should be close

Should nt too hard, one of the guys on here was running 140rwkw N/A vp calais if i remember right

[Cobez]

Why 145rwkw specifically?

i own that motor now its running a wade 992 cam but it also has ported heads and a slight increase in compression. If you were to bump the comp up some more and run a bigger cam you'd get it but i think anything close to that is decent.

if forced induction is an option, i'd just go and grab an sc14 and bolt that on. easy and cheap power

Why 145rwkw specifically?

stupid reason. beat my mate who pulls 140rwkw in a vs clubsport but i like the amonut of power he has its nice its there if you want it but its not rediculusly race only purpose.

buy the supercharger in my shed and youll be well on your way to 145rwkw

He'll still beat you, it will have more torque.

Wouldn't a VS Clubby make more than 140rwkw?

Also, 2 cars that make similar rwkw on a dyno can drive very differently on the road. You've got to remember that dynos are primarily a tuning tool.

not without mods no

Well there you go. Thanks for that.

Beat me to it. Torque wins the race!

masive head work.
get a real good machine shop to bore the block then sleeve it to fit chev 400 piston.
don't for get to upgrade the oil pump mains caps and oil passages if you go that way.
A local guy races commodore engine in speed way and gets about 600hp out of them.
he works at the machining place so can do all this.
MUST have torque plates to to the machining or nothing will be round.

torque plates?

[greenfoam]

powerslave has his engine for sale I think? it's a 140 rwkw V6, But you will need much more power than that to beat the 5 litre with 140

[centy]

plates that they bolt to the block or head to pull the block/head into the shape it will be in when assembled.
Apparently the v6's warp when assembled and tensioned so good machinist use torque plates to prewarp the block so when they bore and hone it it will be round when assembled.
same thing when line boring and doing valve guides and seats if you want it right.

another thing to help you beat him is learn how to drive it like you stole it and have the cops chasing you.

load up box and diff when taking off from a start.

[Zuicider]

never heard of that centy, if its bolted in correctly and the tool is sharp and coolant is applied there should not be any chance of the bore going oval. never had the oval problem with line boring either. unless u have a clapped out machine with excessive backlash

[Pub247]

torque plate boring and honing is nothing new any decent machine shop should use this it simulates a head being bolted on so your bores and nice and true
i dont know what your talking about with guides and valve seats. I think you should noy beleive everything you read and working in a business reconditions motors teaches you more than the internet can....

Yep, rule with a VN seems to be to load it up so hard the body begins to groan/creak.. if you don't get to that point, your foot is not hard enough on the brake.

[centy]

you can go just a little more if you realy try.
The american have been working these engines for big power many more yeatrs then we have so are the best place to go for answers.
Also local engine reco guy has and uses torque plates for his work.

[customvt]

stroker kit with heavily ported heads and good exaust and you should beat him
