ETS intake was installed today, needs some fine tuning as im going lean above 5500RPM, but in general spool up is better by 400-600RPM compared to stick airbox with drop in K&N filter.

Im not matching your spool up numbers but it could because of the heat and elevation. I was testing in 105F and elevation of 2300ft. I see 20psi at 3900RPM and 26psi at 4300RPM.

Once final tune is updated i will take it to a dyno.

Adding some pictures from today

 

That's good to hear. Yea, opening up the intake helps a good amount on spool with larger turbos.

 

Did you upgrade bigger MAF housing with ETS intake?

 

No I'm using stock size MAF.

The intake definitely added more air in, the high map logs showed more air and AFR went leaner than before.

We are still doing some more street tuning to get things dailed perfectly.

 

I was told that Aaron at ER says the oem maf housing is just fine for the 18k

 

With any good amount of boost on ethanol, the stock maf will max out quickly with the 18K.

At 24 psi at 7400 RPM, even the AEM intake (larger maf) hits 4.8v. The same car with stock maf maxed out 5v at 22 psi out the top.

Exact same car with a 3.5" MAF intake, 24.5 psi @ 7400 rpm, MAF = 4.3v

 

Interesting, thanks for the info. I'll look into the ETS maf adapter. Or reconsider a 3.5" Intake setup

 

I'd grab a good 3" for the 18k. No need for a 3.5

 

Car tune is almost finalized. Just have few knock here and there nothing major. I was checking my MAF and it was reaching 4.8v on the high map pushing 30psi on 91 pump gas and methanol 50/50 mix. I never pegged the stock maf at 5v but we are very close. A larger turbo than 18k will definitely need a larger MAF. Boost drop to 26psi at 7800RPM.

On the low map seeing 25psi peak, MAF highest reading were around 4.2v. Boost drop to 22psi at 7800RPM.

Spool up is much better now, getting 20psi at 3400RPM on high map in 4th gear runs and 20psi at 3800RPM in 3rd gear runs.

We are getting there to put it on the dyno soon.

 

One thing im considering now is a larger Methanol tank. I used the rear window washer tank and it was fine with stock turbo and 225ml nozzle. It used to last for a long time.

Now with 675ml nozzle, i filled my tank last night before doing 9 runs in either 3rd or 4th gear with one run going from a standing start to 100mph, it did it in around 8.5-9 seconds as per the logs so i was happy with that.

I rechecked how much i used and i was shocked, 1/4 of the tank is gone. At this rate i will need to refill the washer fluid tank twice every fuel refill if i used the high map with meth alot. Need to pick my battle better now lol
