3.5" on F22 will yield less boost vs F20.

 

so All-in-All how many people here On the s2ki have gone beyond the tech2 7psi pulley and still running more than that on CTSC.
And what are the power difference Before and after?
As I read somewhere in a tread before..the Maximum for AP1 SC is a 3.19" pulley to make the Peak available Efficient Rpm on the SC which if I remember is around 55-57000 RPM on the SC right...?
And that possibly will yield around 13 psi +/- more or less right...?
And Above that isn't what Paxton Rated it for ..
So to make it most of it its possible to keep the Stock CR and Tune it without a Knock on regular gas and Get the most WHP out of the Novi 1000 on a F20c Engine...

 

IM on a 3.5 inch pulley (ap1) at 9200rpm
im at 10.8psi
4060385 is the belt im using as well
stock head and gasket (upgraded valves and springs)

 

I would be worried about pressurizing that CTAE manifold, especially given the fact that its temp will always be fluctuating, which is just going to weaken it over time.

I don't think its a good candidate for forced induction

 

Don't wait 3 days for a belt. Just go to a NAPA store and get a 25-060385. Should be about $20.

 

called summit, no luck..had 4060380 or 4060390, but not the 385. jegs? not familiar, but thanks!

bc: I think I saw it on Amazon, but was still looking, that may be my only option.

 

ya i think NAPA should have a cross reference belt .....they are pretty good to deal with...but i had mine when i ordered from Amazon in like 3 days to my door....so i guess its how fast you need it??

 

I wanted to ask something for all you guys who installed the AEM yourself.
I have a 1012 unit and I Cross-referenced it with the user manual about the Pinouts of the A,B, and C connectors on the OEM ECU and the EMS,
I Found 4 points that I am kind of Concerned so I need to get it out of the way.
1.First the A3 and A4 pins on the A connector to the ECU don't have a thing connected to them and they are Empty and on the AEM EMS pinout is says A3 EVAP Bypass solenoid Valve and A4 says EVAP control Canister Vent,
2. The OEM ECU A31 says VAP(air pump voltage signal) and on the EMS That Spot is Empty.
3.on the OEM C24 there is nothing and on the AEM EMS there is Air Pump Electric Current Sensor.

On the end should this Matter and should I change something?

In the end are there any boosted CTSC Out there with Stock Pulley and Tuned on AEM EMS?

I think that the Carbon of the CTAE can hold the Pressure...And in the end its not too much of a Pressure.
Thanks.

Doesn't matter, don't worry.

Yes there are a few out there.

 

I asked since European and US OEM ECUs differ a Little in Wire connections right?

It seems there are Fewer Members with More Aggressive boost on CTSC than I Imagined,
