Question for guys who actually have the the Roush Kit

[Stymee]

Where did I say "1" gallon?



The car has trapped 124 with the blower and street tires. 110 was only when it had race fuel in it.



The DA here in Phoenix is regularly that high.. Right now it is 4500+

You didn’t, I was saying just delute it even more than 50/50. Try 90/10 just for a teeny bit of safety and a slight spike in octane.

Ok so I was correct, your at a seriously high DA... That makes sense now...You need to come to Atco by me in Oct air but your just a bit to far away

Correct me if I am wrong, but I think hlfbkd420 results were before Roush's latest updates.

4500 DA is not good but I would still have expected a supercharged car to run mid 11s at 122 or so.

Well my buddies RS3 ran 11.1@123 at Englishtown Raceway on a 90 degree day, shitty prep but he was cooled down for a while

If 420 was heat soaked at 4500+ when he made the run I would say 118 would be ok at best but not so great, however which revision of tuning does he run?

My car has had two tunes. Whatever was current in January, and what was put on last Thursday. All runs at the track were with the same tune from January.

Well hopefully u will get some runs soon with this new tune, just let her cool down for a while once u at to the track, then u and 2 guys push her to the line, fire her up just before getting into the water and I bet she rocks

The have been some hardware upgrades, too, IIRC. Do you have those?

I had the new LTR, TB, and tune installed on Thursday of last week.

Could u tell us what your think of the new TB and LTR

Just curious as to how different each piece looks, how does the car drive too

 

[hlfbkd420]

I will let you know when I go to the strip next Friday. I drive 5 miles in town to work every day. Not quite an optimal time to wind her up if you know what I mean. I did roll race a hellcat the other day from 30 to 70 or 80mph and he wasn't happy with the outcome.. He turned off before we could meet up at the upcoming red light. (and he made a point to instigate the race and follow me)

I agree, it has to help with 95-97 octane

And if his car is charged and trapping 118, unless he’s in +5000 DA’s then yes somethings wrong

 

[Bloney]

Hey guys, just received the new updated/larger LTR/HE from Roush. Thought I'd share a couple pics. Also to those that have warrantied the old HE for the new one, did you pay for the install or did Roush cover the install?

Exactly, so u figure 1 gallon of MS109 to 9 gallons on 93 would be fine for a roush charged mustang even on its conservative tuning

I would imagine poss. a bit more more timing and less chance of retard

Win!!!!

I added enough boostane to get it to 97 octane and the tune didn’t like it. First, I didn’t notice and difference and second, it would hesitate starting after driving a bit and then shutting it off. After talking to Roush agent he said he didn’t believe their tune would not adjust timing for it. But you are correct on a stock Ford tune. It will adjust to 97 which is why I mixed to 97. In the end their disclaimer is enough to reject a warranty claim so since I didn’t see a benefit I stopped suing it.

Does anyone have a pic of the original heat exchanger that came before the larger updated design?

Exactly I want a side by side
