Stock vs. Visconti Stage 2 OTS - Dragy Gains

[B58_ hwAyaq]

Keeping it short - Marshall and John at Visconti have been a pleasure to deal with and are incredibly responsive. They bench unlocked my ECU with a super fast turnaround, and they provided me with an OTS tune that absolutely woke the car up. It's a blast, and the numbers show really nice gains IMO for an OTS file.

Breaking into the 11s on the street (and on street tires) was a highlight for me, and I look forward to pushing the car a bit further. I wanted to make this thread to document my numbers and give others an idea of what to expect with a Visconti Stage 2 OTS tune (93 octane).

2020 Supra 3.0 Premium Mods:
CG Precisions DS-1 Catted Downpipe
Visconti Stage 2 OTS (via Ecutek)
Michelin PSS 295s in the rear

Awesome data and comparison post. Just curious what fuel the Visconti Stage 2 map was for - guessing it was 93 pump if your in FL?

Yes, 93 Octane. Updated the thread - I knew I'd forget something.

Would be curious to see your results on a prepped track. I have my comparisons from last season to this season at my local 1/4 and it’s somewhat similar to yours. Prep vs street is a HUGE factor that I’d be curious about

I agree, but I have no plans at the moment to make it to a track (I’ll report back if that changes).

I imagine the prep would be good for a couple tenths in ET due to a presumably better 60ft, but trap speeds should be similar on the track vs. street.

My next step would be flex, and I’d definitely be wary of repeated prepped track launches at that power level on stock axles. I also have no plans of upgrading axles, so the 40-130 range is what I’m really after. I like a good 1/4 mile time/trap to chat about, though, so my street dragy runs will do.

Happy to answer any other questions.

Can be improved. I’ve seen many stock Supra’s run high 11s. Maybe a little corn juice?

2-ports on the unprepped street on 300tw street tires?

Genuinely curious.

And I’m eyeing flex next.

I personally ran 11.9 unprep bone stock but i am 6 port so maybe it’s a big difference

I’ve seen reports of stock 6-ports trapping 113mph which is good for 11.8 per cptnslo above. If you got a good 60ft on the street, that adds up. I admit my launch on this car has some room for improvement.

Driver aside, I think a 118mph trap is great for an OTS file.

Here is a great example of what ethanol can do. My car is configured EXACTLY the same as yours, even down to the CG catted downpipe. The only difference is I have a Visconti custom E50 tune. At roughly the same DA my car does 60-130 in 8.43 sec and quarter mile trap is 126 mph on my Dragy.

Definitely something to look forward to. Thanks for the info!

Anyone have any ideas of how E50 with 91 compares to E50 with 93?

 

[65sohc]

Octane will be greater than 100 with either blend so it is unlikely there would be a performance difference. My mix is with 91.

It only increases the overall octane rating by 1. On a 13 gal mix of E50 it goes from 98.5 to 99.5. Not a big enough difference to worry about.

What tires are you running for this time?
