The PDF Link got messed up. We are fixing it now. I will post it when it is working correctly.

 

Awesome thanks!!

Well I have had my Stillen kit on for approximately 10,000 miles and I could not be happier. I am still on the stock kit other than the fact that I installed PMAS Maf sensors and got a custom tune @ National Speed. After Vlad was done with my tune, I am putting 433 hp and 331 ft lbs of tq to the rear wheel (dynojet). Very solid number IMO and got rid of all the little irritations I had with the turn key flash (rough idle and and some bogging when I dropped the hammer). also in the highway on long trips I average over 30MPG which is amazing for a car with that much power

 

Good to see that you are happy with the SC after 10K miles. I put about 8K Km (5K miles) on mine last summer and while I am happy with the high RPM performance the under 3K rpm is really about the same as NA. Are you auto or 6MT? I sure don't get the mileage that you are getting. Maybe it is a function of how I drive... but my best is about 25 MPG to a larger Canadian gallon, which I am actually fine with. I never bought this car for gas mileage and even NA maybe 28MPG was the best I would get cruising, though that is not at 55 MPH.

I am interested to hear your experience with the MAF sensors. I have an Osiris tune. I considered ECU Tech but I already had an Osiris licence and didn't see any obvious performance gains. When I spoke with ECU Tech they suggested that the placement of the MAF sensors was not optimal in the Stillen design and there was some interference from "backwash" from the blower. They said they could "tune around the issue" and basically ignore some of the false readings. I had my tuner do something similar but it required data logging and real time adjustments. This took three "ride alongs" so it wasn't a trivial process. I don't see how just changing the sensors without relocating them would solve the issue. Can you offer your thoughts on the improvements with the new sensors?

As a sidebar issue... how is your traction? i'm running 255 Pilot Sports on the back and they are not doing the job. My wish list for next year is new wheels and 305 rears.

 

OK... this may be a crazy question, but I was wondering if anyone was using NOS in conjunction with a SC or forced induction setup? I feel that the car could be more responsive in low RPM with a small shot (maybe 50) that would add TQ in the 2500 - 4000 RPM range where it is ho-hum in performance. I'm happy with the SC after 4K so would have the shot only in the low range. Maybe this is gluttony but there is an Alpha 7 GT-R in the family and ever time I ride in that car it makes mine feel slow.

I found some guys on mustang forums that are using both SC and NOS but haven't seen any G or Z applications.

 

^ I would be concerned if the car is tuned on Uprev, because the design of the Stillen SC places the MAFs before the blower and since tuning is done with the MAFs on Uprev it makes things trickier. Then on top of this you would be adding a shot of NOS... Perhaps if it is tuned on Ecutek the results may be 'safer' since it can be tuned with speed density.

I can definitely see a 600whp GTR making a 400whp G feel slow!

 

Thanks for your thoughts TTV36...

Don't the MAFs have to be in front of the blower? Wouldn't there be a crazy amount of air volume if they were after? When I spoke with ECU Tek they suggested that the MAF location was too close to the blower, thus the interference. Part of this I am assuming is mechanical vibration. Their solution was simply to ignore (tune out) erratic readings on the low end. The Uprev solution is the same, except I had them done under real driving conditions, not on a dyno. I am not convinced that the ECU Tek is better. I sent them my dyno and they could not see any issues or promise any improvements in performance. The programmability of ECU Tek and feature are mind numbing and for me add no value. I am willing to pay for performance, not features that I would never use. Can you elaborate on how you would see it as "safer". I assume you are running ECU Tek on your build.

What I'm worried about is the difference in tune between NOS on and off. I know that I will have to go to a colder plug for the NOS and I'm not sure what impact that will have on my normal SC tune. Perhaps a separate map for NOS+SC??? Just trying to figure out how this would / could work together.

 

I am a 6mt. I used to have a sluggish low end response that was about the same as NA but now that I have had a custom tune via UPREV the power comes on strong at roughly 1500-2000 rpm. I went with the different MAFs due to the fact that here in the near future I will be having National Speed ( licensed Stillen dealer and installer) do the stillen "high boost" upgrade to my car and with that the stock MAFs will run out of voltage. They send the blower into vortec and have a custom build done on it (impeller, bearings, changes to a eng oil system instead of the self contained lube system) and put a smaller pulley. So I went ahead and did the mafs in preparation for that upgrade.
As for the traction I have BF Goodwrench sport comp 2s on my car and I absolutely love them. I am running 245 in the front and 285s in the rear(took a lil grinding on the lip where the bumper and fender meet to stop the rubbing, but only the access lip that was there, its still securely attached) I get great traction. Now granted if I slam the gas from a dead stop in first gear its going to roast but as long as you modulate in first I can launch very strong. Next set of rubber I am going to give the PSSs a try. hope this helps brother

 

just one more side not on the traction. I have no more wheel hop when I want to light them up due to my 12k linear rate springs that came on my apexi s1 coilovers

 

Wow... what I would give for strong low end response. I would be really interested in what the gains will be with the high boost upgrade that you are planning. So I am assuming that the stock MAFs are fine voltage wise at the regular SC boost levels? Did you notice any improvements with the new MAFs?
Last year was a bad year for getting Pilot SS as they had production issues. All I could get was the 255s... I wanted 275s. I have nothing but good things to say about the PSS... great traction tire and they last. Thanks for the tip on the wheel hop. I have actually only had that once after a rain... Normally I just spin

 

i can't really give a true assesment of if the MAFs had an effect due to the fact i did not ever have it dyno'd on the canned stillen tune. My tuner Vlad built a whole new map from scratch. I will definatly post about the final results on the "high boost" setup. They are telling me that it is going to be over 500 whp when all said and done. They also said that have done many of the "high boost" upgrades with amazing results. So we will see

 

I've yet to see anyone reach 500whp with the supercharger upgrades. High chances are that you are going to blow something running on an Uprev tune, since the MAFs are in a terrible spot for reading correct IAT. I suggest you get a speed density tune with EcuTek if you intend on doing so or change out the piping and move the MAFs.

 

I hear you milkcow... I also expect that ANMVQ will chime in as he is of the same opinion. that 500WHP is not achievable with the Stillen kit. That's why I was thinking of a piggy back NOS system I am presently at 443 and was pretty happy with that, then fall rolled around and with the cooler temperatures I got a taste of what more power feels like. The cooler more dense air made for much more power.

 

I think Ecutek may be safer because it can be tuned on speed density which ignores the MAF sensor readings and uses RPM, air temperature, and manifold pressure to calculate engine load. Every dyno comparison I have seen so far between Uprev and Ecutek has shown that Ecutek makes more power across the whole sheet.

Unfortunately, I have a VQ35HR so I do not have the opportunity and am tuned with Uprev. We have tried to get it Ecutek to work but the difference in motor features won't allow for it. However, I still recognize that many people are benefitting with more power and features by making the switch to Ecutek.
