I have done dozens of track timeslip/vbox comparos. The ET is almost always identical to the .10 second 9 of ten times. Sometimes the timeslip will be a little quicker. The vbox almost never reads quicker. But if you can really get a consistent .10 quicker at ATCO then the Vbox, that is quicker than Sac or Famoso.

Drews VT3 project build is the end result of our work over the past 2 years to design a low compression option for the S65 motor. This design will allow the S65 to run 10:1 CR which will allow the use of higher boost safely on pump fuel. A requirement in our design process was the ability to use the OEM Alusil cylinders in order to achieve OEM oil consumption levels, cylinder noise and engine longevity. The only way we feel to do this is to keep the stock displacement and use a custom made Mahle Alusil spec piston that will allow a factory seal by using the OEM BMW piston rings. This requires a motor that is in perfect working condition as we use the original block and cylinder machining. We do not sleeve or bore out the motor for this upgrade as this will compromise the Alusil cylinder seal quality. As an added precaution we also upgrade the rod and main bearings to add another level of safety to the design.

Outside of the motor we have designed a custom fuel delivery system that will allow proper fueling for the elevated levels of boost we will run and a custom belt drive system that retains the factory tensioner. The combination of these upgrades will allow the Vortech V3 supercharger to make 700+ HP on our existing VT2 hardware while retaining OEM quality drivability to the vehicle.

say the motor had done 100,000miles would the cylinder holes be round still, dont they get bigger over time and how much boost will this motor be able to take?

don't think i've EVER heard of anything like this happening on any motor. i understand the cylinder becoming weaker over a certain amount of time due to normal wear and tear. But never heard of a cylinder becoming "bigger over time."

isnt the wear and tear by defenition removing material from the cylinder walls so in effect making the bore bigger? hence the need to bore and sleeve and/or go with larger rings.

you could be very correct sir... i've just never heard anyone saying it that way. "i have 100,000 miles and my clyylinders are a lot bigger so i have to replace the cylinder walls."

yes thats a better way to put it!! so can you go with bigger rings and not need to sleeve the motor, iv seen gintani put sleeves in there stage 3 motors i would think its a good idea if you wanted to run big boost

We measure the cylinders to ensure proper specification before assembly. If any problem is found a new block will be sourced. Boring and rehoning a Alusil cylinder is a process which rarely ends up well in terms of cylinder seal quality. Sleeving can be done, however there are several drawbacks and potential issues with installing sleeves in an engine like this. The best solution in our opinion is to reuse the stock Alusil bore, retain the structural integrity of the block and run custom designed Mahle LC pistons designed for boost with OEM grade PWC and piston coating. It is an expensive solution, but the end result is an engine that runs like a stock motor with no durability compromises or excessive oil consumption/engine noise.

I've put close to 2K miles on the car since the Stage 3 build, the oil level indicator has not moved and I have not had to add any oil yet.

how long to you think it would take for the cylinder to be no good? we all dont want to leave it to late! haha and how much boost will you guys run on this motor

PG did some research on this and ultimately decided against sleeving. PG saw tightie's sleeved bottom end being assembled at Auto Talent and liked what he saw. So when it came time to make the decision himself, he researched it a bit, and here's what he came up with.

PG told me that the machine shop who bores all of the stroker motors for RD Sport refused to sleeve the S65 block when PG asked about it. By the time PG asked about sleeving in mid-2010, the machine shop had already bored 8 or 9 S65 strokers. They said the S65 block is very strong, but sleeving it would weaken it too much and they refused to do it. PG asked Dinan the same thing and got the same answer. PG then asked the his race shop buddies their advice (same guys he chose to build his motor), and after looking at the S65 block, they advised against it as well. After hearing three recommendations against it, PG decided it wasn't a good idea to ignore all three recommendation and he decided against sleeving the block.

Nice! That 60-130mph looks fairly close to around 6 seconds. Were you able to top your VT2-625 times?

Ive taken multiple bmw engine apart well after 100K miles, you can still see the original honing marks on the cylinder walls almost everytime. You will usually see conicity if you have some wrist pin issues early on.
