LS! stroked. What supercharger?

[HZute-efi-VS5L]

Ok. So many know about my engine issues I had in my GTO..

Good news! No split sleeves! Very lucky!

So Im now looking at getting Dynomotive in VIC to build my engine to a 383 stroker.

So I guess Im after feedback on Dynomotive. Engine comes with full 12 months warrenty on parts and machining.

Engine will be built with the following:
Manley steel 4340 crankshaft
Compstar/callies “H” beam con rods
CP forged pistons (10.5:1 comp)
Fully machined block
Torque plate honed .005”
Balanced and blueprinted
Cnc ported “243” LS2 casting heads
Custom cam shaft to suit heads
Dual comp cams valve spring set
Double row timing chain set
Hi flow oil pump
Hi Performance hydrulic lifters
Chrome moly pushrods
Yella Terra roller rockers
25% underdrive harmonic balancer
Arp balancer bolt
Arp head stud kit

So my Raptor Blower wont be big enough. So what type of supercharger should I go for? I dont want something crazy! or something that puts my engine on edge. I want something with plenty of go but easy to drive like the raptor is. Do I go side mount? Or maybe top mount?\

I can still use my intercooler I gather?

Car is a 6 Speed with genuine Tru trac 3.9 diff. Gearbox and Diff are both brand new.

Cheers!

The local guys that will be fitting it and tuning it. recomend the Whipple charger?

[evl.346]

procharger/2300/whipple.
depends if you want low down grunt or something that has a good top end?

[HZute-efi-VS5L]

Honestly I dont want something that is hard to drive. So the missas can drive it if she wanted. So dont want it darty. Hense why I want supercharged not turbo. Smooth overall power I guess.

People will generally recommend what they personally run themselves. I'm just finishing a Harrop HTV2300 build on mine, I like the bottom end kick of top mount PD blowers. Whipple are a good piece of gear too. If I was to go centrifugal (side mount), I'd get a pro charger.
Go on you tube and look up vids from marks workshop, that guy has fitted more superchargers than I've had hot dinners.

Best to run what you builder has experience with. Any of the above will crap all over the raptor.

was half way through editing my post then time expired

but i have the 2300 and i love the instant grunt low down. its very easy to drive (manual) my gf drives it easily and says its actually easier to drive mine over her own car.
They only boost under 3/4-full throttle meaning it drives like a std car unless opened up and very economical off boost.

never had a ride in a procharged or whippled car so cant comment on those

honestly i wouldn't let dynomotive touch my car with a 10ft pole.. after ****ing a clutch install, 3 diffs and axles in my mates car i'd suggest you do a bit of a search on them first

a 383 stroker and a whipple?? you must have incredibly deep pockets if you are considering that. you won't be getting much change out of $25k for that kind of build.

if you are looking for something easy to drive look at a side mount blower or a turbo set-up. A big PD blower on a built engine will deliver you massive gobs of power right off idle but might not be what you are looking for, whereas thats exactly what i would kill to have. It's horses for courses my friend. If you were really happy with the drive style of a centry blower i'd be going down that route again. A PD blower like a whipple will be a completely different animal.

you'll be looking at a good clutch with the kinds of power you will be putting down either way, so there's another $2k. food for thought

[HZute-efi-VS5L]

interesting about dynomotive feedback. Searching produces some brilliant feedback also......

Clutch. Yes already have a near new twin plate button thing. (2k worth)

[HZute-efi-VS5L]

double post.

[VY-SV8]

if it was me going PD blower, i'd be looking at a Eaton TVS series of blowers. With the internal bypass valve it makes them far more economical to run on a street car when you don't need massive levels of boost, a system that cannot be done on a whipple due to their design. Not to mention they are about 8-10% more efficient across the board at anything under about 20psi.

[evl.346]

Agree with the above comment. Magnusson blowers are also cheaper compared to the harrop version and also whipple chargers.

[jezza85]

I went a 2.9 whipple with the plan to throw in a 427ci bottom end in with in the next 12 months, but this combo wont get you much change out of 30k.

If you want something that your wife can drive id be looking at a procharger or vortech style side mount. 383 will give you tyre frying torque in n/a form sooo would be a handle full with the top mount for your wife. Least with a side mount she should be able to drive it at low revs with bugger all boost which without knowing what your wife is like when it comes to drive should suit and will keep you happy when you eventually mash the pedal and build the revs.

Its probably not worth stroking your motor out if you plan to go forced induction. The better value for money would be to pickup an iron block and transfer your reusable parts over. The problem with a stroked LS1 is you dont have a huge amount of sidewall strength left for high boost applications. Considering the relatively minor price difference id do it properly from the start.

That said, a properly built N/A LS1 stroker will drive really well (although the "numbers" might not look as impressive). The most important thing is to work out EXACTLY what your going to do BEFORE you spend a single dollar on it. Try to build the engine to a set plan, not just upgrading bits as you go along.

Also, whatever your budget is double it to do what your thinking of doing. Costs always come up and theres no point taking shortcuts as it will bite you in the long run.

Whatever you end up doing... post lots of pics.
