Question for guys who actually have the the Roush Kit

[Nsinclair]

Hello Gents, been awhile.
I got a decent deal on some F14s and they came with front runners and ET street Rs, I never bothered to notice they were 26s instead of the 28s my PP1 stock wheels were. Besides looking funny on the car, they make my car sit low enough where I scrape my driveway pretty badly. Would the 28s be a performance loss at the track with an A10 car? (I bought a curb ramp hoping to stop my scraping with the 26s)

Also I can only find front runners in 28 tall in bias ply. Is that correct or am I missing something, thanks.

Question for those of you that had the Roush Phase 2 calibration and then switched to a custom tune. Do you think the performance and transmission shift improvement is significant enough over the Roush Phase 2 calibration to warrant going that route or knowing what you know now would you have stayed with the Roush Phase 2 calibration? Thanks!

To piggyback on this good question, now that nGauge is dead, what are PBD and VMP using?

(I am not sure anyone with the latest P2 tune has gone custom, yet. It is a lot better than the original P2 tune.)

I will also add... Don't spill that shit on ANYTHING! I can see why it turns yours plugs orange. Last time I put some in (hardly ever) I pulled the funnel out and somehow I got little droplets on the side of the car below the gas tank. I walked into the house to get a towel and before I even got back it was dried on the car and was dark black. It came off with no problem but I'm glad I noticed it!

I had the original Roush p2 tune then switched to a custom from PBD. I never did any logging with the original Roush p2 tune but, subjectively, I thought the PBD tune was just as good if not marginally better than the Roush tune.

It seemed to me the 93 octane PBD tune felt more violent doing pulls as in the power came on quicker. It also seemed to make more attempts to manage heat by forcing fans to full speed and keeping the fans on longer after the car was off or idling. I don’t remember the Roush doing this without the p2 button trick. I never encountered major heat soak issues with the Roush or PBD tune. Again, no real data to back this up, just my impressions.

Is the PBD tune worth it over Roush? For me it was because I went the e85 route and I enjoy messing with my car. If I was looking for a more “hands off” approach I may have stuck with the Roush tune.

PBD is using something now called a uCAL. I guess I got one of the last Ngauges so I don’t know much about the uCALs.

Thanks for your feedback. How are you liking E85 on the Roush blower? I don’t think I’ve seen any feedback from anyone running E85 on the Roush 2650.

I actually made the switch last weekend so i havent had a whole lot of time with it but, so far, it rocks. Ran it out of 93 on Friday about a quarter mile from my fuel jugs. 7 miles to empty is actually zero with a Fore fuel hat FYI. The car really woke up with E (and no tune revisions yet) and runs smoother almost quieter.

The really weird thing, and i am not sure if it is by design or it is a mistake in the PBD tune, all the heat management tricks are turned off. The IC pump doesnt run with the door open and the fans don't run any extra. Ethanol is more tolerant to high intake temps so all that may be by design but the lack of noise when i shut off my car is eerie.

Hopefully, i will get some data to back all my talk up once the rain goes away but so far .

Look forward to hearing your feedback when you get more seat time on E85.

what did you do to the fuel system for e85?

He mentioned a Fore fuel hat so I’m guessing he is running a Fore Innovation Fuel System.

Hey, I got a question about your Mishimoto coolant tank. When the engine is cold should the level be at the lowest mark?

 

[jtgdg5]

what did you do to the fuel system for e85?

ID1050x injectors, Fore dual pump system(ti auto 274s), single return regulator. The pumps are wired to run together. I may stage them in the future if fuel heat becomes an issue. I don't drive that much so it may be ok. Installation is tedious getting the AN fittings right but not overly difficult.

Honestly, I have never really paid attention. I am not sure how accurate that site glass is. If the Mishimoto has sufficient volume, it may not fluctuate all that much. I just make sure the air/coolant interface is visible.

 

[Matthewstorm]

OK, thnx. I ask because today I saw it for the first time after install and the level was at the minimum mark. The engine was cold. Just wondering. Do you think it's made any difference in cooling?
Thanks.

That ET at that DA is awesome, In NJ temps in the fall, your car would FLY

U should be very happy with that ET IN AZ.
