VAC Motorsports | VAC 4.4 S65 Stroker Kit Build (CP, Carrillo, Darton, Schrick)

swamp2 · 01-08-2013, 08:48 PM

Wow finally!

In summary...

539 (crank) hp - 30% gain
394 (crank) ft lb - 34% gain

122.5 hp/l VAC
103.5 hp/l stock

More torque at 3500 rpm than peak torque of stock engine (for all those who are torque obsessed...)

Impressive

swamp2 · 01-08-2013, 08:55 PM

VAC: How "aggressive" is this build? More precisely:

Is this still a daily driver, suitable for all climates, and use on track as well as a grocery getter?
Will it run well on all of the various high octane "pump" fuels across the country?
Any reason to believe the engines lifespan is significantly altered?
Is the rpm limit raised?
Any warranty offered?

Any cost information available yet?

Brian_VACsales · 01-08-2013, 08:58 PM

Another project:

4.4, 13:1, custom aggressive cams and one off headers (e46 fitment) made 570/395 on the same dyno. Fatter curver and made power well past 8k.

A 600hp, 100 octane 4.4 is absolutely possible. These are all track cars, so they are running after market ECUs.

Our S65s are for track cars. We have not explored the stock DME, that's not really our target market.

This build came in in the low 30s with billet dry sump. Not a bad price really.

So would vac be unwilling to provide customers who daily their cars the gts treatment. Namely the increased stroke on the stock bore with a custom crank and new cams that will shift the power curve to the right unlike the the present stroked motor options (dinan, rd sport). I believe several of the the tuners who frequent this forum would be willing to tune on the stock dme.

Brian_VACsales · 01-08-2013, 10:49 PM

Unwilling is not the right word, we simply have not gotten to the street stroker kits yet. We have everything but the tuning sorted and proven - that is actually quite achievable, just need to coordinate and allocate the time. 2014-2015 hopefully

Trust me, I'd LOVE to be able to offer such a solution for sale. We are not there yet, but IMO we are still in the beginning of the mod lifecycle for the S65. In 2012 we built quite a few track and street M10s, M20s, S14s, M/S5Xs, and S54s. For the S65, we haven't seen anything yet ;-)

Can't wait! I'm surprised it's been this long, I'd be willing to sell another car right now for a streetable 4.4 s65 and proper brakes.

OM VT3 · 01-09-2013, 01:46 AM

How about a low comp motor? Any info about that 4.4 you guys did with the vf supercharger on it?

Very nice honesty/integrity here.

M3PO · 01-10-2013, 05:12 PM

I would love to have something like this over an SC, any day. And twice on sundays!

I'm with you, surely there is a motor builder that can give our motors the gts treatment.

Chrishkm5 · 09-22-2013, 12:49 AM

Do you guys offer similar stoker for M5 E60 pr N85 engine by any chance

?

SECOND2NONE · 09-22-2013, 08:25 AM

How much would a build like this cost, but for a boosted engine.. You can pm me if you want

KmndntKlink · 09-22-2013, 12:17 PM

Damn this looks sick, really wish you'd sell this to 'regular' customers. Don't really want to go with dinan, their gains are nice but nothing compared to this, great job VAC! I'd be all over a 590hp/400tq stroker in the next few years

. Staying tuned (heh) for sure!

BMWM4 · 09-22-2013, 05:35 PM

so this is all NA no supercharger was installed on this setup? just a question though, why go through all this trouble instead of just adding a supercharger? whats the benefit of this over a super charger? sorry for the beginner question guys, trying to learn a little.

Imran@Evolve · 09-23-2013, 11:43 AM

Great work guys. We would love to tune a street version of this set up. May have to stroke the Evolve E92 M3 ;-)

These are track cars and the rules may prohibit the use of a huffer or any other FI. Also, alot of guy like running NA such as myself.

There's nothing like cubic inches... and an 8,400 RPM redline.

Awesome work! VAC ftw

Jive · 10-17-2013, 03:05 PM

Honest question, would this engine not be considered streetable due to an inability to pass emissions and it would also be incredibly uncomfortable/difficult to drive due to the more aggressive cams?
