Eventuri intake, ETS catted downpipe (to replace the catless one I have on now), and Boost Logic titanium exhaust with black tips and valved option going on today and tomorrow, along with updated tuning.

Some photos of the titanium exhaust with the valves - the shop gushed over the quality. They posted a sound clip on their IG story, but it expired. I will add when I get the car back in the garage. I went with black tips and look forward to seeing in person.

Any updates on tuning with the Pure upgrade?

Lost a little on the top end as I went from catless to catted DP- torque the same, likely no difference in seat of the pants. Tune is very conservative for 91 octane and 115 degree heat in AZ - was 485 or so at the wheels. I guess there is another 100-200 whp with 100 octane, E85, meth, etc. I can say the car drives perfectly and is as fast as I could ever need, but nice to know a lot more is there with a change of fuel and re-tune.

Your engine is begging for ethanol.

Good to know, weather here is similar to AZ and was also aiming for 500whp on pump gas

Ordered and now the waiting game

At least it doesn't look like leftovers from an erector set.

What is the octane rating??

 

[a90moe]

What is the octane rating??

93 octane

Hope it would be possible

93 octane

Hope it would be possible

You'll have more power available with 93.

Glad to hear this. IMO perfect all around number for this chasis esp running pump gas

A couple questions. Did you do your own 93 tune or did you use a local shop (I'm in Tucson and there aren't many tuners local)? Why did you reverse from catless to catted? 93 octane isn't widespread down here and so I've been thinking of just a stage 1/91 tune.

My tune is for 91 as that is the best we can get. Dyno-Comp in Scottsdale as as good as anyone and I would highly recommend them. They tuned for great street driving, not a peak number to post on a forum. They did offer to put in race gas and do a high power tune to take out to a race event, but I declined. The Pure 800 in my car is running over 700 at the wheels with the right fuel and that is available to me at any time as well as anyone with the same setup.

I went to the catted DP as I has some residual fuel/exhaust fumes in the garage after shutdown and a there was a suggestion that a cat would lessen that. As it stands I added 200 flyweel hp and the car is as fast as I could ever need it as I'm not going to the track.

I prefer the 91 as well. I may look into Dyno-Comp. I haven't done the DP route yet...still stock here. I'm not interested in the track either but a catted DP and a tune sounds like something I'm interested in. Did you notice much change in the sound from catless to catted? The Pure line of turbos seems pretty good. Frankly, tho, I don't need 700whp. I'm shooting for 400-500 or so...nothing extraordinary. Thanks for the info!
