EPL/Tial Alpha 28rs turbos installed
 

After seeing Cossey's dyno and ridiculous torque curve with these turbos, I was sold. I had been set on k24/18g for months and when I was ready to pull the trigger, I saw these new and improved alpha turbos start coming out. That low end torque sold me.

Just got everything installed over the weekend (not me personally, as I have no skills!) and the conservative base tune flashed yesterday after Tony left for his 2 week vacation. Big thanks to Tony and Dave @ EPL for getting me taken care of in their hectic time! Love the remote flash option with the EPL flash loader program. Sweet.

Car and Mods:

01 996TT
EPL/Tial Alpha 28rs
72# injectors
EPL flash for 91 octane
Fabspeed Maxflo exhaust
Sachs/GT3RS clutch/LWFW
RWD conversion
EVOMS DV's
stock airbox/filter


First impressions:

Going from a EVOMS/GIAC stage 2 kit (on the car when I got it) everything is already much better: low end drivability, low end power (obviously!) and smooth idling. I didn't realize how choppy that GIAC tune really was at low speeds/RPM until driving with this tune the past 2 days. And with much bigger injectors now.

With only .9 to 1 bar max boost until I can datalog and upload the next flash when Tony gets back, I am already impressed with the new power in 1st and 2nd gears especially. Breaks the tires lose in those gears a little bit at only .9 bar. I am rubbing Toyo T1R 315s in back.

I can't wait to get the high boost flash done! It's gonna be a long 2 weeks. :D
I just got a Performance Box too and also plan to dyno this new setup at Stasis. And I am already setting myself up to do the meth kit sooner or later.

Does it ever stop? :eek:

Anyway, I am stoked to have some new power and will update with 60-130s, dyno #s, and maybe a 1/4 mile ET soon....

Cheers.

very nice.. what do those turbo's cost?

Can't wait to see what kind of times you run.
Make sure Mike gives you some of his "secret tips":D on how to run a 60-130, he sure has done well himself!

Yeah, seeing as no one else with Alphas are posting any times...I'm curious too. I don't think the Alphas have a tremendous advantage 60-130 as you are starting at around 2500-3000rpm anyway, but I'm very sure they will perform.....if anyone can do it Davey can!!!!hilarious

I am thinking of going with this set up... would love to know performance #'s and costs

Congrats on getting everything in Dave!

I would be interested in your 60-130s if you can get some even with only the shelf tune.

Congrats - where the turbos cheaper than the one I am selling:confused:

Why are you interested in his...where's yours?:D

I had a 7.20s with my GT660 in cool weather which is on the list. Since I upgraded slightly to a GT700 I have not been able to better that time in the hot weather. Hopefully when the weather improves I can do better.

OK, didn't check the list...you're free to go...:D

Thanks. You will have to ask Tony for an exact price, but I will say they are not substantially more than the k24/18g turbos. :)

I know! Mike needs to take me under his wing. :D

I agree Mike. After seeing the dyno and now driving a couple days, I think the advantage is 0-60 or stoplight to stoplight, which I can find in the city here. :D
Will be interesting to see 60-130 compared to the 24/18.

Yeah I might actually do that since I have a couple weeks til Tony gets back. I gotta put the Pbox together and figure that thing out. If the number is terrible, maybe I will just keep it to myself. hilarious

Not cheaper, but also not the same. These outflow yours by quite a bit I am told.

Yeah, what Mike said. :D

these are gt28 with what size wheels?

I wish I could tell you specifics. I do not know exactly other than they are billet compressor wheels. Just what I was told.

Maybe Tony or TialSport can chime in here at some point with more specifics?

Well done David, I know it took a while to figure stuff out but glad you're happy with the results too;) Now hopefully you can get that American muscle done too!

Well, my friend you finally pulled the trigger, congrats!! You will love those turbos, they are incredible for low end and mid range power. I am looking forward to see some crazy numbers. I am glad you finally made up your mind. Enjoy brother.
