Looks like a fun setup! Congrats!

Damn!

Epic. Single turbo ftw. Supra sounding

Great job with the build

[Wanted_M]

Congrats, that 8474 putting in some work!
I'd like to share this video comparing EFR 8474 vs G35-1050, two turbos F80 folks look at for stock motor. Was an eye opener for me.

Congrats, very nice. I’ve been following your build closely. Great numbers on 93 pump gas, 4N makes the best turbo kit on the market so 600whp is no problem on pump gas. Did you happen to consider any of the single inlet intercoolers out there? I’m curious about the delta between the dual and single inlet. Wagner and EOS both offer their own single inlet intercooler.

Yeah 4N definitely has the best single turbo setup as of today. It’s all about that equal length manifold. I considered the single inlet intercooler it, I already had the dual Wagner and I didn’t want to pay the extra cost to switch.

The sound is intoxicating in person. The video doesn’t do any justice.

Thanks!! The setup is a handful to say the least. Lol

Yeah I saw that video and one of the reasons I went with the EFR8474 as it just walks all over the G35-1050.

Nice numbers! I'm especially impressed with the performance on 93oct. How much boost were you running on that 93oct pull? Also, do you mind sharing who your tuner is? I'm considering the 4n kit for my n55.

[SYT_Shadow]

Very cool. I'm only interested in the 93 numbers as it's hard/impossible to find E50 or E anything at road courses, at least around here.

But the 93 numbers look nice! not a ton of torque but plenty of power! How is the lag over 4k rpm?

I suppose the water injection system is intact and doing its thing?

[CT92F80]

Great numbers! Any plans to run E85 and or meth injection? Wondering how much more is on tap

Yes, 93 is the focus as that is what I use for track days. Using ethanol is for fun on the street. The idea and goal was to keep torque low to save the rods and to mimic the normal GTS linear power delivery.

Lag??? Nahhh man...Pulls like a freight train once you get around 3400 rpm.

Yes, water injection works like normal and drinks water like a fish! I wouldn't have it any other way.

93 octane was around 25-26 psi and 28-29 psi on e50. 4N kit is the best! There are some minor tweaking that needs to be done as its a tuner kit but, nonetheless they're the only vendor on the market that I know that has the equal length manifold design which is the key! I'm not a fan of the shorty long style.

I can easily run full e85 but, I really don't see a need. IMO this is already a ton of power and a lot to handle. No need for meth injection at all. I already have factory water injection. This setup is what I call keeping it simple. No extra crap like PI w/ Reflex+, meth, etc...my motto is keep it simple. This build is for track usage.

[astris]

Very cool. Who did the tuning?

Would be super interested in what 60-130 you could clock. You’re making more hp, but less torque than my setup.

[McBobby Jr]

I’m curious what gains a set of Schrick Cams would net you on this exact same setup. I see the turbo pushes power well beyond 7000 RPM.

I'm curious as well, given how the power delivery looks between a smaller twin and a single setup.

What fenders do you have on the car?

Motiv did the tuning. I don’t have any tools to check the 60-130mph times. I’m more interested to see how the setup it performs on track.

That would be interesting. I’m sure that might require a built motor going down that rabbit hole.

Would you mind describing some of the minor tweaks you needed to do for install? Any fab work necessary? Just trying to get a feel for the level/type of tweaking needed.

Yes, you will need to fab the exhaust and possibly do some cutting depending on your air intake choice. I don't think the air filter in the engine bay is a great option so I opted for the front mount which requires some cutting.

[Soul Coughing]

Great numbers! Does this turbo have a internal wastegate? Or did you run an external one? And if so, does it dump back into the downpipe or separately?
