We've seen many pictures of the installation of the flip drive but has anyone seen a increase in boost with just installing this drive?

I'm curious too! Unless your getting belt slip I don't think you will see an increase. I would say the biggest advantage would be for someone who wants to pulley down and overspin their blower.
madmatt9471 just finished installing his flip drive and will be on the rollers in a couple of weeks. Let's see if he makes any more boost considering he's not changing pulley sizes.

It will be curious to see how many of us have belt slippage.

Why I am going 8 rib and later this could be an option

R6_C5_CLS55

I pullied down on my F1R from 8 rib 4.2 to 8 rib 3.85 combined with a 7.25 ATI balancer. At 7K engine RPM the blower impeller will be at ~97% of the maximum rating. The car should be on the dyno within the next two weeks. Since I am using a LS2 block and AFR 225 heads and only have four studs per cylinder we also made several restrictor plates made to test with this set-up so I can keep the steep ramp up in boost but limit boost up top to avoid head lift.

How much boost do you think you will make est?
I have a ysi 2.85 pulley and 16 psi stock ls7 block

R6_C5_CLS55

Without any restrictor in the inlet, I think it will make 25 PSI at 7,000 RPM. I don't think we will be able to keep the heads planted at that power / boost level so we will use the restrictor plates to limit the peak boost / power.

My Novi kit would slip a little more after each dyno pull. Every non cog system will have some slip ...

I will be doing some Dyno Pulls on Monday April 6th @ RPM Motors (Charlie)

We will doing doing some clean-up/tweaking on the tune, I have a goal of what I'd like to get - so we will see

Thanks,Matt

The F1R is just taking off at 65K, you'll need to spin it near 80K to see 25psi. Head lifting should not be problem as long as you keep detonation and cylinder temps down-a cam with overlap will go a long way there. Folks have made 30psi+ with 10 bolt heads no problem, again just don't let it rattle and don't depend on the kock sensors to tell you when it's rattling.

Ron all the belt slippage occurs around the crank pulley, the Flip drive should go a long way to eleviate any of that. I think we'll finally be able to get the most out of our blowers now.

R6_C5_CLS55

According to ATI the maximum impeller speed is 68K RPM. I don't plan to exceed that so I will be spinning a maximum of just under 66K RPM. Previously, at just under 59K RPM the manifold pressure was very near 20 PSI (19.4 PSI read digitally). I guess I'll get whatever it makes with the balancer, blower pulley, and flip drive on the car now.

I have not heard of anyone making 30+ PSI reliably with 10 stud heads / blocks, especially not ones that are not o-ringed. Can you point me to some of these people as I would like to ask them how they have their cars set up and what kind of maintenance that type of set up requires?

Out of curiosity, to what do you attribute the bug push for and development of the Warhawk and LSX 6 stud / cylinder blocks and heads?

Thanks.

Anyone making a cog set-up that works with the Flip Drive ?

STEALTH 99 C5

The flip drive will do it's job where it counts , on the track and the street . You may not see an increase in power on the dyno , just more consistent numbers , as many see belt slip after a few pulls without the flip drive installed .

0Arun@ChampionMotors

Cog will only work with a auto-the stick will toss belts. I think a YSi can be spun with 35mm belt, as well as a F1A or C, the R may require a 50mm.

Hey Arun I am excited to change over to the flip drive,and make more boost,we only managed to get 16lbs,how much more can we expect,out of my set up and I spoke with Mikey and were hoping to get the automatic in place.asap.

ajg1915

I'm going to convert back to an auto from a six speed as I am just going to drive the car on the street for fun.

IPS Motorsports

2.85 inch pulley and only 16 psi, interesting, I would have guessed that small of a pulley making more boost. What compression ratio are you running?

As for the COG setup Arun is mostly correct you need to have the auto in the car!

Could someone please post some pics of this system !! thank you .. anyone have it on a ecs novi set up

What are you hiding up your sleave bro!
