New turbo setup for more psi!

[DDLopes]

So last year I was able to finally get my 13' PP SHO all back together after a long time having the engine built after catastrophic engine failure. I opted to have RMB Motorworks build me a stage 2 shortblock with boostline rods and custom coated JE pistons. It also came with the CSS to help the block deal with the extra power. The heads were sent out to Headsgames for their pocket port R option along with Ferrea comp plus valves and manley locks. For turbos I opt for the GH Gen3R setup. I also have the GH intercooler and torque converter. There's also all the typical add ons meth kit, XDI injectors, XDI evo pump, Hellcat pump, EPP hot pipes, EPP CAI, MSD coils, PPE downpipes and full custom exhaust to name a few things. Anyways once the car was broken in and Brad and I straightened out the tune. I took the car to the dyno to see what kind of numbers it would put down. I was hoping to see 600 whp but unfortunately I was well short. The best the car could do is 530 whp and 560 pounds of torque. Still great numbers but I was hoping for more. After doing some research I realized the only transverse 3.5 that I could find were all running ATP turbos. I thought the GH Gen3R turbos would be capable of doing the same numbers if not be at least within 25-30 whp. But in my case it just wasn't possible. Now for my fuel I run 93 octane with VP x85 for a E30 tune. I also run a stage 3 meth kit with 2 nozzles spraying VP M1 methanol. I think my issue trying to reach 600 whp is the GH turbos are at 100% wastegate at 22 psi. While the ATP turbos are capable of reaching 26-27 psi at 100% wastegate. So I reached out to Turbo Bay performance to see if they could build me something to achieve at least 26psi. Mat said he could do it but it would take some time due to testing. I wasn't in a rush so I sent him a set of factory Ford turbos and let him do his thing. I will admit it took much longer than I anticipated but the workmanship was worth it. Now the turbo outlet diameter is just over 2" and Mat says these turbos are good for at least 28 psi. They are getting installed next week so hopefully within a couple of months I'll be back on the dyno to see what these turbos can make.

Badass build and those turbos look awesome! I’ve never heard someone say anything bad about Matt over at TurboBay, looks clear to me he takes pride in his work. Those things are clean! Excited to hear the results!

 

[SHOdded]

idk if there is a map sensor reliable at those extremes. i guess you stay 21 psi or less you should be solid. do you have the efficiency envelope for these turbos?

EXCITING

No I didn’t the efficiency envelope but I’ll ask mat for it. Yes your correct with the map sensor but Brad is able to work around it.

Very excited to hear how the turbos perform!
Mine are still patiently waiting in their bubble wrap. I like his tag on them. I didn't get that on mine.

I’ll post the results. Once there installed Matt at TurboBay wants me to drive 200 miles with no WOT to break them in. After that Brad and I will start the tuning process. I think to hit the 600 whp I’ll need to run them around 26 psi. I’d love to run them solely off the wastegate while the car is on the Dyno to see what there max hp …. But well that would have to be discussed with Brad and the Dyno shop. Good luck with your turbos!!! Did you get the stage 4 as well…??

You know it's been so long (July 2022) I can't even remember what I have lol. I know I sent him brand new turbos straight from Ford and about the only thing he used was the housings. I basically told him to do everything he possibly could with the stock fitment. So, of course, I know I got the billet wheels and I believe it's honed out as much as possible.

Well good luck with your setup. I’m sure you’ll be happy with them. Looks like my GH Gen3R’s will be up for sale… lol they only have about 600-800 miles

Im honestly suprised youre nowhere close to 600 with the setup you had. Possible Brad's playing extra safe or maybe you're fueling isn't the best? I'm full bolt on (GH IC, 3 bar map, PPE catted DPs, 170 tstat, AD mounts, XDI 35 HPFP, lighter wheels with pilot sports) basically everything but turbos. I have a flex though so a little different than you guys and im barely able to break into the 12s. Granted im like 5-600 pounds heavier, other flex's with my setup are doing high 12s full weight. I also am tuned with Brad so hes pushing it as far as he feels safe which i dont blame him but I thought 12s would be a cakewalk for me at this point. I will be trying Matt for a e30 tune and once ironed out, i plan on going to the dyno and doing a couple of pulls to see kinda numbers I get with both tunes. My goal was 12s in the 1/4, not a particular whp number but i feel as if maybe its not making the number i see most others are making with my setup. I was actually hoping for somewhere near 500 so you being at 530 with the kitchen sink thrown at it, makes me rethink about what i would be getting lol

With my last setup on the stock long block but all the typical bolt ons I made 433 whp. My fuel was 93 octane with 1 can of Boostane plus my meth setup. If that helps. But every Dyno is different so my 433 here could be 460-470 somewhere else. Dynos are all different. I’m going back on the same Dyno and trying to go back when the weather is similar. It should make more power simply because these turbos are capable of producing more boost. But I agree Brad likes to keep it on the safe side which is absolutely the right thing to do for any reputable tuner. At the end of the day if your happy with your cars performance while your in the throttle than don’t worry about the Dyno number. It’s very expensive to chase a high number… LOL

DD, that makes me very happy to hear of your numbers knowing my closest ethanol fuel is about six light years from Vermont :-/

Haha… I buy 5 gallon cans of VP racing X85. E85 at the pump can range from 70-85… specially in the winter

Increased dyno HP and quarter mile times will not necessarily corelate. The trans (torque management) will hold you back.

All makes sense!
I think all of the stresses the importance of torque converter, LSD mods, and clutches to increase efficiency. However, I have a feeling if you're on stock clutches the life will be decreased significantly. Thoughts?

I agree the electronic management of this car can be difficult to work around at times. Specially when you start going over 22psi of boost.

Depends on how you drive and how you maintain your car… unless you try driving around with 600 whp like your running from the cops… lol that will definitely have replaced your trans much sooner than you want to!

It is a tough line! I think I got them near 15K into the new build so I want to be able to drive the damn thing the way I want.
I would prefer the trans not be the fusible link but sooner or later something has to give so I suppose I shouldn't complain about electronic management though, I probably will

I bought it in 5 gallons like DD in the past from Epping NH but I’ve got a plug for Sunoco E85-R 55 gallon drums in UnderHill VT now. My buddy paid $100 for the year and he gets free shipping on unlimited drums ….no brainer! Shipping for stuff like that can get brutal!

Edit:$453 per drum

lol… a drum would last me 8-10 years!! I only go through 2 tanks of gas a year!! Lmfao it’s just a toy. But this summer I’m gonna drive it more

Holy crap! When mine was running I thought 2k miles was barely driving it for a year ….
