    • 997.1 Turbo E85 tuned by Protomotive results - Over 600 alll wheel horsepower on stock turbos

      What you see below in the video is a 997.1 Porsche 911 Turbo tuned on E85 by Todd at Protomotive. Additional modifications to the car are a Europipe exhaust, 997.2 Turbo intercoolers, upgraded Sachs clutch (car is manual), upgraded fuel injectors, and BMC filters. The dyno used is a Mainline dyno from Australia which is considered a "heartbreaker" dyno. Todd Knighton estimates the Mainline reads roughly 15-17% lower than a Dynojet.


      The Mainline read out 578 to all four wheels. Let's conservatively estimate this at the mid 600 wheel range on a Dynojet. Until the car is run on a Dynojet we do not know for sure but it is safe to say this is over 600 horsepower at the wheels on the stock turbos when using E85 ethanol fuel.

      This is one of those times that it is important to understand how different dynos can read completely different numbers.

        Actually I'm just going to go with what the graph states as I don't see anything showing 587?

        Owner posted this over at 6speed "Peak boost was 22psi @ 3500rpm, which held pretty steady to 5000rpm where it was about 21.6. From there it falls pretty rapidly down to 19psi at 6000rpm, and 17psi by 7000rpm"

        Turbo Inlet Pipes & an Aftermarket Y-Pipe would easily set this car over 600, possible 625 WHP+. M3ntal illustrated how much of an impact these mods on his 996, picking up 50 WHP midrange with just the Y-Pipe

        Any solid data on turbo inlet pipes and y-pipe gain on 997tt cars?

        I would presume similar gains. The OEM Y-Pipe is 54mm in diameter, and most Y-Pipes you'll see are 2.5" (64mm) or 3" (76mm).

        Regarding turbo inlet piping, there's two "camps" -- The first is fender-well intakes located in front of the intercooler (like this, Protomotive uses this setup in their kits)
        Attachment 34017

        Camp 2 is retaining the stock airbox/filter location, which AMS supports. I'm in agreement with them, and support what Megion did (the blue 997 Turbo in all the DragTimes videos), just 3" welded piping with some K&N filters in the stock airbox location.

        Bottom line, regardless which setup you go with you'll need 3" piping if you're running anything beyond a stock VTG turbo.


        IF you're gonna find concrete data, I'd browse 6Speed's Forum since there's a strong Porsche Turbo presence there, between DIY owners & reputable vendors.

        The turbo inlets works good on 996tt cars for sure
        On 997tt vgts or modded vgts I could find any before and after tests

        The y-pipe alone gain 10bhp.

        It is funny coz evoms and champions has turbo inlets for while but no before and aftet tests yet.

        What im sure about out is that stock turbo inlet works good on 63.5mm vgts ( 65mm maybe )

        Posts like this make me wonder if I should stick with my 996T or just ditch it and bump up to the 997T? Anyone else have that itch?

        Y Pipe and E85 with the larger injectors etc... anything with e85 seems to gain much more whp than one would expect with a decent tuner

        If there isn't a cost issue the 997 is better in every way. It's more pleasant to look at, sit in, etc. Potential is equal between the two as far as power anyway if it's a 997.1.

        Oh hey, this is my car. I just read through this, it actually did make 587 on one of the pulls but I don't think it was legit. I think it ran into the dyno brake or something otherwise because it spiked up at the end.

        I did put inlet pipes on it later but never got a chance to put it back on the same Dyno as the shop has since sold it. I don't think the 997 will pick up as much with a Y-pipe upgrade as a 996, the 997 Y-pipe is a much better design.

        It picked up quite a bit on the inlet pipes, holding boost a little better to 7000. I have now swapped to upgraded VTGs, and Cobb Accessport. I'm completely out of fuel but the car is pretty fast. Derived from the datalog it did 60-100 in 2.42 seconds. Planning on swapping to some ID1300s and am looking into whether or not the fuel pumps are going to be enough now...

        Thanks for the added info.

        Swapping in the injectors should be a no-brainer at this point.

        Yeah your car is going to be really fast Rix.

        Also Hi everyone! I will put up more posts on here once I am back in the states.

        Thanks

        2.42 60-100 is very fast man! your in mid 5sec 60-130 territories with these time! you can think about a meth kit as a fuel adder and a knock suppressor to!

        997.1's are really nice with the right bolt-ons. I just dynoed at 530awhp on a Dyno Dynamics dyno (similar to mustang) with cobb ap stage 2, 997.2 ic's, kline catless exhaust, stock turbos, stock everything else. This was my baseline. Yesterday new 1000cc injectors were put in and today we'll be doing an e85 calibration.

        In my opionion the ypipes, plenums and inlet pipes aren't worth it until you're on big upgraded turbos. It's just not cost effective for what you get when on stock turbos.
