The MaxTuning 900hp S14...

[Master Chief]

Hi guys.
Haven't been around here for a while but i thought it would be nice to share some details on our latest build.
The MaxTuning Drag S14.

Over [email protected] (that would be about [email protected]) from a 2.0L Sr20Det S14.
Here is a better look of the dyno graph - notice the amazing torque curve.
This is all at 35 psi.

Check out a small video of the dyno pull, and some pics of the build.

Thanks for looking !!!

[JDMfrank]

Very nice figure's, Gave you a like on Facebook.

[fliprayzin240sx]

Make a build thread...its been a while since you've posted anything about the setup.

[jr_ss]

Perhaps you should translate and/or list more details. I personally cannot read your website.

[blueshark123]

Any info on the rear tire setup?

[bova17]

damn straight

[Master Chief]

Here are some specs

Sr20det black top with vtc.
87mm cp pistons.
Tomei Conrods.
Apexi 1.2mm HG.
Mazworx uprate apr head bolts.
Acl calico bearings.
MaxTuning special prepped head with Supertech valves springs and retainers.
Tomei 270 in/ex solid cams and solid lifters conversion.
Precision 6466 billet turbo, with .82 A/R vband inlet outlet housing.
Greddy short intake manifold with 70mm Nissan throttle body.
Bosch 2000cc injectors with dual entry/one return Greddy fuel rail.
Dual aeromotive 340 pump system, with MaxTuning design pump hanger.
Haltech sport 2000 engine management with 4 egt's.

Probably forgetting a lot of stuff...

[Tank_4g63]

Who is still tuning on egts in this day and time?

Still... nice work.

[Master Chief]

What is that supposed to mean?
I don't see a serious tuner passing out on good egt data.
If you are referring to tuning only with egt that is not the case here.
I just mentioned 4 egt's, as this is not trivial on most setups.

Any info on the rear tire setup?

Right now iam running on Mickey Thompsons 275/60 15" ET Street Radial.
On the "Track" they are ok, but on the highway the car starts getting sideways as soon as i get to 7000-7500 RPM in third - and this is after a full alignment was done.
Either there is something wrong with the tires, or i should be using a small side wall tire on the street.
Not sure yet.

Have to get a new clutch before i can do more testing...

Wow this thing is sweet, I wanna see more of this.

[Master Chief]

From the last race. Didnt go so well as we broke an input shaft and had major ignition problems, but i guess there is always, next time...

[510-SR20DET]

I did not see if you mention about the block. Is it sleeved? More info on the block please, 35psi on sr20 is insane.

[jr_ss]

Over [email protected] (that would be about [email protected]) from a 2.0L Sr20Det S14.

That's more than 940hp at the crank if you plug in the generic 20% for drivetrain losses.

[Master Chief]

We measure at the hubs, so from our experience its about 20-30 hp from the crank power, and not procentage.

The block is not sleeved, but it is an interesting experiment.
;-)

[R33E8]

What transmission were you running when the input shaft broke? And are you guys running AC and power steering??

[jr_ss]

We measure at the hubs, so from our experience its about 20-30 hp from the crank power, and not procentage.

;-)

Regardless you still have drivetrain losses. Even when measuring at the hubs you still have to take into account the power eaten up by the transmission and the differential. I'd think it's safe to say its over 1000hp at the crank.

[Master Chief]

Yes. There are losses, but usually most of them are due to the tires and traction.
Measuring at the hubs we eliminate those factors.
So yes, there are still loses but from measuring stock cars compared to the claimed numbers from the manufacturers, we usually see around 20-30 ho difference form hub to crank on RWD. About 10-15 ho loss for FWD and about 30-45 for RWD.
1000 @ crank seems a bit high to me. In any case it is very fast, when it grips.

We are using the z32 box, stock for now. We brok an input shaft at the diff, not at the gearbox.
However, I think it was due to wheel hoop off the line.
We will try to fix this somehow.

We are running both power steering and a/c.
The car is in full street trim.
The only real discomfort is the noise from the exhaust.

[slow92]

Nice numbers. This keeps me motivated to finish my car, even though it won't be done until next spring/summer.

[fliprayzin240sx]

Are you still running the stock R200 rear end or upgraded to the larger R230s off the GTRs/Z32 TTs?

[jr_ss]

I would hope that he upgraded to the larger differential.

[Master Chief]

No. Still R200.
The problem is that I already have the DSS drive shafts, and they won't fit to the r230 input shafts without mods as far as I know.
The real problem seems to be the input shafts, not the diff.
Looking into some upgraded input shafts.

[madserv]

Simple awesome setup. :) i hope i also get these figures. :) Subscribed !~

[[email protected]]

Switch over to R32 GT-R standard mechanical diff. Strongest and most reliable R200 I've seen to date

[2muchboost]

Amazing build....congrats

[moowee240]

I got a new set from autozone..the first thing I noticed was that the shaft was much much larger..thought it was the wrong one.. but it fit perfect ..it was noticeably 5 to 10 mm larger..ill mic the difference between the two tomorrow .

[jr_ss]

It's typically the CVs and not the shafts that are the weak links.

[moowee240]

I've seen a lot of shafts break at the splines into the cv joint. Not the cv itself. And a larger shaft will improve durability. Not to say that it doesn't happen but I just noticed the cv shafts I got were much beafer than stock.. in any case they would have had to change the whole cv joint assembly to use the bigger diam. Shaft anyhow so its a totally different unit than stock..not just a reman..

[Hoffman5982]

I see on the parts list you say s14 sr with VTC, but surely with 270 cams you deleted vtc right?

Dont need sleeves, im rocking a very similiar setup up with a 35r. 19lbs 91oct im sitting at 560whp

Well, as similar as apples to oranges maybe. This dude is running almost double your boost and makes almost double the power.

Great setup, that torque curve is amazing. I would like to see a build thread :)

I was referencing open deck, .40 bore making big power.

[zenki 95]

Revival, crazy numbers! Awesome build. I've been watching all the Au vids posted up at the site and wow what a passion for cars and big power+1

[Master Chief]

Thanks mate, although this one is not from Australia (if that is what you meant).

[zurud]

What's your 1/4 mile time? I suggest bias ply slick. Drag radial sometimes cause wheelhop that will break drivetrain. Post your time slip and video

yay for power after 6000 rpms.

on a side note, a lot of time was spent on this, loving the EGT setup on the manifold.

[zenki 95]

Who made the mani? Im still in shock ha. Must of had some crazy head work

[Master Chief]

With big power come big problems.
We are just replacing the clutch right now and a broken selector fork in the gear box.
A couple of weeks ago we killed our carbon fiber driveshaft and just installed a new one from PST through mazworx.

So videos will come soon.
1/4 mile numbers will be a while.
We don't have a real track here, so it's just an airport and its hard getting traction.
That's why I think the street radias will work better for now.
Still, there is some experimentation to be done.

About the exhaust manifold it's from synapse turbo.
.: Home :: Synapse Turbo :. (http://www.synapseturbo.com/)

The head was special ported by my shop, MaxTuning.
The cams are 270 solids custom tuned to my specs.
Supertech valve train and twin guide conversion from mazworx help us pull to
Over 9000 rpm if we dare. We don't. ;)

I'd say its all in the tuning and matching up the right components.

Open deck? This isn't a Honda...

[zenki 95]

Thanks for the details. I just rebuilt my sr so if I ever redo it for big power ill send the head out to you guys for sure! I'm gonna be aiming to 500hp max for now.

I tried to look up the rest of the details on fb on your build that I couldn't find, you posted em so thanks man gl

[Master Chief]

Basiclly most stuff are posted on the first page of this tread.
If want to know about something specific, ask away.
