Question for guys who actually have the the Roush Kit

[JasinEdward]

I see higher temps than I like in Michigan also. Didn't you get an ice box at one time? Have you thought about a KC?

I have a Killer Chiller in the garage waiting to go on.... should be done by the end of the month. Everything I have seen in regards to the results of installing a KC is what I am aiming towards. I'll have to get a BAP too... then I'll shoot for 9's.... I've already run 10.4 at 133. Iat2's on that run started at 126 and ended at 155.... there is more in this car for sure.... 60' was a 1.7 on that run...

i have the phase 2 exchanger and that email is based on the vmp tune.... not roush.... the iat2s you say you have are not normal.... they are significantly lower than most.

on



At that time I had the phase 2 h/e and they are referring to the VMP tune... The fact that you have seen no higher than 140 at the end of a pull is INSANE.... even more so on an 80 degree day....

The other day it was 66 out and I did a nice pull on the highway... iat2's at the beginning? 120.... iat2's at the end? 146...

If it was only 66 and your IAT2 was 120 when moving, that seems abnormal to me unless you were stuck idling in traffic or something. How long was the pull that picked up 26 degrees?

I will freely admit that I have not had any impressive times yet. On a 65 degree day, I ran 11.2 @ 128 but the low fuel pressure CEL came on at 99 mph so I went home. After getting that fixed, a few weeks later, when temps were in the low 80s, I ran 3 times and was consistently in the 11.3 range. Could not get a 60 out of the 1.9-2.1 range to save my ass. I just kept blowing the tires off. Car seemed to pull well once hooked, though.

I then got the new cal but it had the 123 bug so didn't bother running again.

Can't wait to see what you can do with the KC.

Nah..... 120 is pretty normal. In 60 degree weather it will creep down to 100, but as soon as I make a pull it's back up....

Me too...

Oddly was reading on the odin thread most say they are seeing 30-40 above ambient iat2’s after all the bashing the roush has received and the fact lund wont tune it but the odin is basically the same supercharger with a larger throttle body and the loki would be the same with a smaller tb. Idk abt the heat soak or recovery times/temps but for a inverted blower i had assumed the intercoolers would have done much better than the roush.

A Wisconsin track had a test/tune yesterday that was originally supposed to start at 9. Temps were in the 40s at that time! They first delayed the start until 10:30 but that turned into noon. Temps had risen to 63.....still very good.

I made 3 runs back to back. Unfortunately, there were so many cars, each run was separated by 30 minutes waiting in staging lines. The car is super consistent as you can see with the last run slightly better. I would love to blame tires or track prep for my poor 60s but it is probably my fault. Fine line between too soft and too hard of a launch. If I could ever hit the sweet spot and get a 60 in the 1.5 range, the car would have a 10.8 or better in it.

There were 3 other S550s there on DRs and all were in the low 12s. They were great guys and we had a lot of fun. My car is in the right lane. The green Mustang in the left.

Be careful about how you compare. I’ve been looking at a lot of manifold charge temp data (MCT, IAT2) in hopes of improving mine. There’s a big difference between settle-out temp and wot temp. MCT with my Whipple kit will settle out 15-25 deg over ambient and I would like to improve this. Ever 15 deg MCT = 1 deg spark advance when knock limited = 20 hp. I suspect the quoted temps are settle-out temps. For wot, I’m looking at a roush phase 2 log where it had settled out 35-40 deg over ambient. At wot the MCT shoots up quickly and at the end of a 9 second pull, MCT was 75 deg over ambient.

I just love this sound!

I just love this sound!

I haven’t followed this ridiculously long thread in a while. Car sounds freaking great. Can you hear any whine underneath the growl? What’s your best pass? Have you dynoed it?

U went 10’s after a long hiatus
It will only go faster now

So happy for you Bruce

No whine at all. I am not sure a TVS blower has any whine. Best so far is 10.9@129. I know there is more to be had if I can just 60 better. Never on a dyno. Car is heavy and fully optioned with stock Roush tune. I will eventually get a 10.8 or better out of it.

They whine. Loud exhausts drown it out in the cabin very easily.

I am happy with the consistency but disappointed in myself for not getting a 1.5-1.6 60 foot time. Other guys gave done it. I will too.
