Most all my customers use SCT for logging.

But any logging software can gather the same info.

The filter over the headers is a major contributor to loss of power with heat.

what would be the best option to combat this issue?

I had the duct work from paxton that places the filter behind the headlight. I took that off and mounted a filter directly on the unit, it seemed like it ran better that way, even with the filter sitting above the headers.

You may need my Tensioner relocation kit and different belt routing.

How would the belt routing contribute to the issue im having?

That tube is your best option, it may initially feel better when everything is cold with the filter over the headers.

But the Tube will be more consistent.

It is common for the tensioner to compress the belt against it self and cause belt slippage.

Let it cool off totally and see if the power is back like it was before it gets hot, If it is yes chalk it up to high IAT's and timing. do a visual CK on meth if its in the washer bottle like most and its full to lid then a hard pull it will drop to bottom of neck. your tune is safest for meth so if you run out then your not gonna blow up something. You would of seen it on the dyno if you had belt slippage Unless its a old ass belt and been a while. I guess a real hard pull could screw up a tensioner if the tensioner spring has a lot of hot cold cycles and get over sprung, but the way you described it.. it was instantly like the next hard pull after the car heated up it didn't fell the same.

The tensioner used to do that, make the belt sides touch one another. This was due to me changing the pulley to the 3.33 and the availability of the perfect belt size being non existent. I was able to drill a new pilot hole for the tensioner to move the tensioner stop about a 1/4 of an inch. This keeps the belt from touching under a load.

Sounds like you went the wrong way with the tensioner which would induce slippage.

To stop the belt from touching you run the bottom side of the belt under the lower Idler pulley.

Yes the Ribs will run on the pulley.

I really dont think it is slipping but I will look at rerouting it that way. This is probably not my issue though as I had the issue before I messed with the tensioner.

I think that even if I were to do normal driving long enough to get temps hot it would still have the loss of power. Meth tank is in the trunk, its about 4gal so its rarely full. Im thinking I really need a way to data log.

Sig pic. Mine is like yours on the filter location. I took my tube off too.

Bo White · 10-17-2014, 02:42 PM

You running a Paxton kit or a ESC kit?
Reason I ask is the Paxton kit comes 7" lower pulley and the ECS is 7.8"
Mine is 7" and 3.12" with 12psi.

paxton kit with 10 rib

Pics of the engine compartment might help

Ted.

Here's a pic as it sits now.
