I was dead set on a 4088 until I read this...

That's amazing that an s366 was able to make that much power at such low boost levels. Does he have dyno sheets to prove it?

Edit: Nevermind... I thought those numbers were from a DSM. Hearsay dyno numbers from a Honda don't mean much to me.

Believe me that is not hear say it's nt my place to vouche for other people but trust me bullet is more then reliable as a source. Sacrh the bullseyepower forums there are others

At a quick glance at the Honda making 750 something at 30psi at the front wheels, that comes to around 630whp in an All-Wheel-Drive vehicle taking into account an additional 15% drivetrain loss. If I saw a dyno sheet showing the HP/tq numbers and curve, along with whatever correction factor, I could make a better "apples-to-apples" approximation vs. my current "apples-to-oranges" approximation.

For reference, I did around 635AWHP on 30psi with the GT4088R on the 0.96 A/R housing.

Could you please enlighten me on the specifications of the Borg Warner turbo used on the honda? I would like to see a compressor map and the wheel diameters used. As well, would you know the Honda's displacement and compression ratio?

I look forward to bringing this thread back to a Borg Warner vs. Garrett conversation.

Thanks,

Thanks,

I hate the i know someone that made x hp game but I"ll hit up mark and tell him to see if he wants to chime in if not than I can not give any more infor then what I already gave. I can find more borg warner comprarisons though from they're site's forum.

I have the maps for the 372 and the 374. If anyone wants them I could post them up

[RipperXX]

Curious of which DSM vendors sell these, most I am looking at don't carry them.

Marti at VIP is the guy to talk to and bullseye power is the company that sells borg turbo's.

[unlmtdndeavor]

I would call or email the guys over at Full Function Full Function: Home they can take care of you. Thats where I get all my stuff

Of course! Please do

[unlmtdndeavor]

I'll post them up when I get off work, the pics are on my personal computer

I have a borg warner s370 that been sitting in my room for 2 months. I need to get a turbine housing for it, manifold etc. to get it on. But i also have aem sitting in my room and that needs to go in first. From what i have measurement wise the s370 is basically a gt4202. Measurements come out the same. Im wondering if i even really wanna run this because im trying to make a more usable power curve.

I am running a g4cs 2.4 with all suporting mods, so it wouldnt be really bad on say a smaller a/r to choke it up a bit but still make mad power up top. I have the s370 for sale brand new if anyone wants it for 800 for now, but once the aem is in a squared away im gonna start gathering stuff to put the turbo on.

[jkimes]

Wow If the s370 is basically the same size as a 4202, then the s374 must be freaking ginormous! Hard to believe a turbo that large spooled similar to the 4088 on that skyline in the link I posted at the beginning of this thread.

[unlmtdndeavor]

I don't believe that is correct. From what I have gathered, the S372 is like a gt4294 and the S374 is like a gt4202. So following that trend, I'd expect an S370 to be like say a gt4094?

Here's what kiggly told me:

Bullseye named these the S372 (with the 70.8mm comp wheel) and S374 (with the 74.5mm comp wheel).

S374 with 1.0AR turbine housing. This is the competitor to a big GT42R, but ~105lb/min

S372 with 0.9AR turbine housing. This is the competitor to a small GT42R, but ~ 95lb/min

Hope that clears things up

Slippi asked me to stop in for some info. Let's see how this goes.

1992awdlaser has the answer for the "dsmlink vs AEM" tangent. Agreed totally.

Now my buddy Jay's Honda; jkimes I appreciate your skepticism. Totally understood. But I can assure you I've been around enough not to make stuff up, lol. No reason and no offense taken.

I posted that info on another forum because of the content in that thread. There is a bit of skepticism on the BW's because they haven't been run too much. Therefore I posted up just as a point of interest/reference. There is however a thread on here on the s256?. Its an interesting read that made me look at the BW's as an very viable possibility for my current project.

Twicks, you are right, apples to apples its not. Its just a statement on the strength of these turbos. There is very little doubt in my mind that this is a mid 850whp fwd turbo. The more interesting thing about these turbos is what you alluded to; the torque curve seems to come on relatively strong and hold on pretty well. Also, the spool up on these seems to be alot like a BB turbo. As for the dyno, I guess I could get over to Jay's at some point and try to post it up. But honestly, with my regular work, and my important work (the car projects, lol) I'm gonna pass on that. But it was tuned by Jeff Evans out of Pennsylvania, so it should be somewhere on his site (I believe he saves all his tunes) You can look under Jay Selander within the past month.

Oh yeah, here are some particulars on his car;

85MM Sleeved Type-R Block (B18C5)
Manley Rods
CP 9.7:1 T-bone Coated Pistons (Hmm, I thought they were 9.0's. Oh well)
OEM GSR Crank
Type-R Ported Head
Skunk2 Pro 1 Cams
Crower Valvetrain
Edelbrock IM
Blox 74MM TB
3" IC Piping
Precision Front Mount
4"DP and 4" Aluminum Exhaust

His S366 has an .82 A/R

I hope that helps a little.

I used a micometer on the compressor 71mm inducer 100mm exducer. this is on a s370 i have. I ment the 4294 sorry

I would love to see what the S374 does, but it is much more along the frame of a GT42R, and would require me to do some extra modifications to try one out.

Personally, I think -- More power to you! Run one and post up the results -- it is all about trial and error, and sometimes you get lucky.

As for streetability -- I think that my GT4088R is extremely streetable. I normally have it setup for street driving with fast spoolup (modified ignition map for early spoolup), resulting in up to 40psi+ of boost reached by 4000-4200rpms, and the insanity ends at redline (set at 8500rpms). For the track, I change my ignition timing back for slower spoolup since I am using a 2-step without anti-lag to build boost at the line. Even with the slow-spoolup ignition timing map, I see full boost around 4500-4700rpms.

The car has currently put down 753AWHP/713TQ @ 40psi peak, falling to 35psi) on a new DynoJet AWD dyno at Beyond Redline Performance in Green Bay, WI after changing over intake manifolds.

It hasn't been to the track yet, but the previous numbers were 741AWHP/696TQ at 49psi peak, falling to 42psi; on a DynoCom AWD dyno (also at Beyond Redline Performance), and track times of 9.96 @ 143mph with a best MPH of 147.88mph at 35psi on Q16 fuel in a 3200# street car on Hoosier QTP slicks.

At 30psi of boost, the old intake manifold (magnus) vs. the new manifold (Beyond Redline) made an additional 108.97 HP and 74.23 TQ with just a manifold swap. The car now makes around 635AWHP at 30psi on Q16 gas.

New Intake manifold numbers:
30psi = 635AWHP/590ish TQ (can't remember)
40psi = 753AWHP/713TQ (boost falling to 35psi at upper rpms)
50psi = ??? -- hopefully around 825AWHP or so.

I really like the Garrett turbos, especially my GT4088R. I definitely would love to see some more numbers put down with these Borg Warner turbos though. It might be worth checking out!

As for popcorn eating..., I am currently on Transmission #16. The car will be back up and running by next week.

My goals for this turbo is to put down solid low-9's, and 155mph trap speeds.

THATS RIDICULOUS!!!!!!!!!!!!! lol haha damn~!!

[unlmtdndeavor]

ok, so I thought I had maps for both the S372 and S374, but I only have it for the latter, which I got in the mail yesterday!

Here are some pics of the S374 vs a gt3076 (~fp3052 which I was running)
I'm excited to say the least

Thanks to the guys over @ FFTEC for getting started on my manifold!

That is one big 14b lol j/k That thing is Ginormous. WHat is that 4" in and 3 " out?

[chavez408]

Fftec carry's the borg warner turbos, edwin?
That thing looks huge compare to that 30r.
I almost purchased a evo IX today mang haha
