Turbo/Efficiency Discussion

[futurevr4man]

Well, I'm not going to sit here and list off the bazillion things I have done on my car. Even though it needs some small tweaks, the big stuff has been bought and it fits the bill to make big power. As far as I know... I have everything (once I get my intake mani/TB in) that you all could come up with to make power with the exception of T3 manifolds.

I was hoping for a thread to discuss making my setup more efficient, not a giant back and forth about turbos or things I know I need to fix. But oh well I suppose. I agree that the 20G's won't hit 800... not on a 3S. Just cause a DSM can hit 400 on one, doesn't mean I'll hit 800 with two. Our heads are just not as efficient.

I also don't want to push the turbo to it's absolute limit to hit the power. I'm thinking FP Greens will be the way to go. 54 lb/min, I'm thinking I can hit 800 around 30psi. I sent an email to FP earlier today to get some input from them. I have 3sx manifolds, JRink has IPS. I believe I have enough room to fit them, but I'll see what FP will do to help me figure it out.

Lastly, JRink didnt even hit 700 on his 3.5L 16G setup. And there is no one (Ray included) that would disagree that his car is set up very well. Ray had nothing but compliments to give about his car. If he can't get close (relatively) easily, why in the world would anyone argue that I could get 800 on 20G's? IDK

I find it hard to believe that only 1 guy has ever made over 700whp on evo3 16gs.

Believe it. Search.

I'll save you some trouble also...quickest 1/4 is 10.3 with evo3s. Trevor.

Most were pushing evo3s before ethanol was popular but race gas and meth were very popular in the builds.

It seems that you haven't done much research on the platform to see what others have done and disregarding solid input to help a member.

Also a big hint was just given above on what to search before building the biggest baddest td04.

I'm definitely with you and believe that greater than 700 is very possible but it's not "easy" on either evo3s or 20gs.

Are you familiar with the Devastators MTC built?

yes ive read up some about them.

Agreed. If you truly want 800, go bigger. But you also said full spool by 4k. Won't happen on Greens. Greens or maybe Reds (900hp) would be a great setup if you can get them to fit. Since your 20g covers fit, the big FPs may also.

Good luck!

I have done research and look around at lots of stuff. I also know the problems with large td04s and I am going to have my try at them. I am a guy that like to solve problems and continue to make things better in everything I work on. There is a lot of technology that has improved on both tuning and turbo performance and efficiency sense many of these guys first did large build, lots of them over 10 years go. wich these improvements, getting 5-10% out of the same size turbo is very possible.

Im not here to fight at all, im just saying its possible.

I actually think the greens are 9xx hp turbos, the red's are 4 digit. 54lbs/min * 2 (greens)? That should definitely be 900 hp range if they were really pushed... aaaaaand 800 if they don't get so pushed

But the 68HTA's have been redone to 51 lb/min (JRinks were the old 47 lb/min kind) so those may fit the bill as well. Idk. Gotta wait for what FP says.

[flewis763]

an efr7163 also may be a good option but very expensive. the 6758 will out perform a billet 20g slightly but for the cost difference it probably would not be worth it for you.

Yes, if pushed. You didn't seem like you wanted to push to the max so I used the 75% figure. BTW, Jrink pushed the old 68's pretty hard and they ended up at 78% of the combined lb/min x 10awhp.

I stick to my 75-80% range for most td05 setups (heads, cams, huge exhaust, big intercooler.) If folks figure out how to match the 10awhp per lb/min that DSMs get, td05s will get very interesting again! Hope you go for it! (Probably a bit unfair though since a 4g has more valve area per turbo.)

Back on efficiency topic....If you don't mind some extra noise in boost, seriously consider modding your 3sx kit's external wastegate to dumps.

[chooch]

If efficiency is your goal, I'm sure the new garrett GTX turbos and Borg Warner are more efficient. I'd be chopping off the TD05 flange and welding a T3 or something on.
Products | Turbochargers
BorgWarner EFR Turbos | Full-Race.com
These companies are great as you get a lot more published data about the turbos than the Mitsubishi turbos. External wastegates should also make the setup more efficient too....

[futurevr4man]

I have external gates already.

With open dumps... man, they are so loud though! I'm not sure I could put up with that haha
