My experience was similar, he actually accommodated doing all the work over the Christmas weekend last year even though he was supposed to be spending time with family etc.!

I was only in town with my fiend's car (from NY) for that exact period of time so I had no other way to let him work on the car.

I will be a lifetime customer!

 

Haven't updated in a little while, been dialing in the car with Sam via Cobb AP. Used 93oct for shakedown, dialed that in then moved on to E85. You may be tired of hearing it but yes E85 is a great fuel for tuning. The car does pull much harder, clear difference. Actually my local E85 stations are E70 year round here in Iowa. E70 is still plenty and actually kinda nice because it will leave some extra head room on your injectors.

The OTS file from Cobb ran great, part throttle, idle etc runs great with the ID 1k injectors. I haven't experienced any throttle hesitation, feels like stock. Working with Sam we bumped timing and boost from the OTS file and settled (or better said him & Mitch cut me off lol) on a conservative tune but the car still pulls hard all the way til redline. I highly recommend stage 3 level mods.

The car is done for now, I possibly may do headers and turbochargers in the future. Just gonna drive it for now.

 

Lol
You've been great to work with bud. We want her to run strong and long
We still have 100hp on the table with turbos for you to look forward to!

 

I'll keep that in mind, always a good chance I'll do it lol. Winter will be here before you know it and the car will just sit for ~3 months. That's a dangerous time because there will be time to mod it again lol.

Thanks again, your customer service has been excellent since day 1.

 

Right back at you. It was a pleasure and your extensive knowledge, detailed attention and awesome thread have helped a lot of people!

 

Let me know if you want to sell and upgrade to a 991TT. =) I'm in the market for one, exactly your spec.

 

Thanks everyone for all the kind comments and encouragement. I really hope the thread helps out other forum members with their projects. May do turbos in winter time, we will see.

 

Very nice build my friend and I envy your hands on talent!!


Have you done any 60-130,1/4 etc testing as of yet?


Thanks

Been starting to play around. Tried the Cobb AP dyno function and I also uploaded data on the Virtual Dyno software others have used. Cobb AP and the datalogs are coming in at 600-620whp roughly (SAE). I may look into getting a vbox for fun.

 

Here are the results using the Virtual Dyno software (free download) with the best specs I could find on the car for simulation. If anyone needs what assumptions I used I could provide them. Results also match a few runs I tried on the Cobb AP dyno app.

The chart is comparing the final calibration on 93oct vs. E85(E70 locally). Based on what I have seen other cars do its running right in line. Sam told me we could get ~600whp conservatively and reliably, I believe he has helped me achieve it. Between him and advice from other members the recipe came together fairly easy. Thanks to everyone who provided input.

How accurate is the software? Multiple articles out there on it. Like any simulation, garbage in garbage out. I would recommend using this as a measuring stick to keep tabs on your car and do comparisons over time and mods. Not bet the farm on it lol.

Enjoy!

 

Such a cool software. Look at those curves! I bet if you put it on the rollers it would look just about like that exactly. I really am happy the way it turned out and would sleep perfectly at night knowing you can nail that car at any RPM in any condition at any speed as long as you own it! We could get a little more but to me this is a great level and it will perform very well consistently. Congrats pal!

 

This car is making some serious power. His MAF flow rates at 20-21 psi are as good as what I've seen on 63mm upgraded compressor wheel VTG upgrades out there. Just proves what the right combo of parts can do with the factory turbos. No doubt this car tuned to max out the factory turbos like mine is would make 680+ whp on the dyno I used.

 

I appreciate you sharing your data with me, helped a ton quickly compare results and find where my tune was conservative vs. one with more work

I can say A418t81's car makes serious power, its no dyno funny business. As you look through the data its very clear, that car is seriously fast! They did a great job on it.

 

Haha, thanks bud. Just takes the right combo of parts, tuning, end user expertise, and a dash of ethanol to make these bad boys insanely fast on the factory turbos. Enjoy your new monster!

 

Figured I would update the thread to share some tweaks that will be coming over winter. Car ran flawless but just like everyone looking to get a little more. Currently trying to decide which turbos to go with, likely will be VTG upgrades. To get the benefits of larger non VGT options I would have to upgrade injectors again (from 1000cc to 1300cc). Not 100% sure i want to swap injectors this winter, not planning on dropping the engine. However I will admit, the couple projects ProTuning has done with the stock engine GT30 builds are quite interesting to say the least Open to suggestions of course ESPECIALLY if you have data. I'm always looking for data as Sam can attest LOL!

First winter upgrade was a 6kW garage heater

Parked the car on Saturday for the winter and the next morning the first snow storm dumped on us.
