900WHP STOCK S58! Spool Performance Upgraded Twin Turbos + Port Injection [RACEBOX M4 EP. 4]

[@ClintG-rh6kh]

That last graph though! What a beautiful powerband! Also look at how this this shop is growing!!! As a part of the family on the infiniti side, its great to see! You guys will be who I return to on the next build! Your pal in Tulsa, Clint

[@goracebox]

We’re very excited about that too! With the close ratio ZF8 trans, shifting at 7k rpm means we’ll be in that 850+whp power band thru the whole pull! This thing is gonna be wild, gotta tidy up a few things on it and take it out.

[@drummerac3]

I fell asleep while watching this last night. I live in The McKinley (high rise in Memorial) and definitely cruising by to check the place out! Didn’t know it was so close on Brittmoore. Bringing a 2023 740i!!!

[@goracebox]

Ngl, falling asleep to car videos on YT is a vibe. 😂 But yea feel free to pull up, if we’re not super busy u can check out the shop!

[@drummerac3]

@@goracebox I’m in. I’ll be there sometime tomorrow. Thanks in advance.

[@luxr6107]

2 weeks overdue, but I’ll accept it 😂 Thanks for another great vid!

[@goracebox]

I’m trying to get a video out every week but it’s tough lol, we got 2 more videos lined up after this so hopefully a content filled month coming up!

[@sumairmaxx]

Keep up the good work guys!

[@loudaccord]

Did you do the 60-130 yet?

[@ZillaFullBoost]

Wahh I wanted to see a race between it and the Z when the M was on stocks 😔

[@goracebox]

Maaaaan we can run it on low boost which makes just over 700whp 😂

[@ZillaFullBoost]

@@goracebox bet! Go make it happen.

[@Kh.J.]

👏🏻👏🏻👏🏻

[@yousefishot]

Did your intake from the stock turbo setup bolt right onto these Spools? Did you need some new inlets or anything? Thanks

[@goracebox]

For this set of turbos, which were the prototype set, Spool had to make a custom inlet to mate up the intakes meant for stock turbos, to the turbo inlets. The production turbos should remedy that.

[@coly0226]

What was the E content on the 900?

[@goracebox]

E67! We could have mixed up more but ran out of ethanol at the shop lol.

[@jrca379]

would love to see you dip into the mk7 mqb platform

[@goracebox]

We actually tune them! On EcuTek and Cobb depending on the setup. We don’t really advertise it since we try to focus on the VR30, B58 and S58, but Hussain does a bunch of Audi/VW tuning!

[@jrca379]

How far into tune do you guys go as in turbo upgrades and stuff like that

[@goracebox]

The last one we did was a MK7.5 Golf R with a full frame turbo and port injection, tuned on EcuTek making right at 500whp on a conservative tune, the customer didn’t want a TCM tune atm so no point turning it up 😭

[@jrca379]

@@goracebox what does a custom tune by you guys usually cost

[@goracebox]

Sorry for the late response, shoot us an email at [e-mail], it depends on ur setup and tuning platform!

[@JonCartman-l1u]

What exact turbos are on the car now?

[@goracebox]

They are Spool’s stock location full frame twin turbos. Currently unreleased, we were able to work with them to get a set for testing.

Stock? By definition… a 900+ horses M car is not stock.

[@goracebox]

Stock engine, I didn’t have room to put “stock longblock S58” in the title, and it also works better for the audience to get my point across in the first 3-4 words in the title and get clicks. 🫡

[@curtdragon]

Y'all don't know what stock means do you lol. Stock longblock but everything else is changed lol

[@goracebox]

I’m not putting “stock longblock” in the title when there’s a word limit lol. Need to let the audience know the premise of the video in the first few words. Most people understand “stock S58” means it’s a stock engine, and if they don’t, they will when they watch the video!

[@aaronfranulovich]

Tech at 2 min sounds like a moron talking about pushing 750 and pushing the car harder. Guys been making more than that on stock turbos and an OTS E50 tune for years.

[@goracebox]

He’s talking about the Z lol. 750whp is up there for the stock VR30, we only push customer cars to that level if they have a healthy car and all the proper supporting mods!

[@stephenEs3532]

give it 3000 HP still cant fix ugly

[@goracebox]

😫

[@TENNESSEETRACKHAWK]

Too bad it weighs as much as a small truck smh

[@goracebox]

This car absolutely moves tho for a 4k lbs car, running 9s 1/4 mile on the street with just downpipes, E50 and stock turbos. I would also go test drive one if u haven’t driven a G8X, they actually feel very nimble for the weight!

[@MarcosOrtiz-e6h]

Almost all sports cars are Close to the 4K lb weight. Just today’s build standards.

[@TENNESSEETRACKHAWK]

@@MarcosOrtiz-e6h Yea I guess so

[@GolfCoyote]

@@goraceboxliterally like 1,400lbs less than a track hawk lol, who the hell is this guy to talk about weight..
