"better" is a matter of opinion around here i think everyone will tell you something different, check the comp maps on both see what you think, i would go with borg, more turbo for the $$$.

Here is the S372 map. She is mighty nice.
Sorry for it being in kgs. The max flow with the stock cover is 94 lbs a min.

God is that a loaded question. Might as well lock the thread now.
I personally prefer the Borg Warner unit. The BW REALLY likes the higher pressure ratios that drag racers are pushing now days. Also with the extended tip compressor wheel (generally speaking from my experience) is that the seem to make power all the way to redline. I have seen this on GT35rs compared to the S362 at redline on the car there was a 50whp difference where at peak power there was only 10 or 12 whp differences. The S362 made more power under the curve.
I have seen the same thing in other setups as well.
Also just go ahead and try to twist the shaft in the S372. IT is about the size of your thumb. I have only heard of ONE breaking in about 50 of them that I know of (not necessarily in an S372, but they where the same size shaft) I have seen GT40s break after only three dyno pulls before.
The Borg Warners are severly over built.
(edit was to change the broken turbos to GT40s instead of GT42)

Get outta here with the bullshit man. lol How many 42's have you seen break after 3 dyno pulls?
I have personally setup and tuned over 20 cars on 42r's, and have NEVER seen a failure that wasn't caused by something going through the motor and hitting the turbine wheel.
I will be doing a true, no BS, test between the two shortly. I will have the best dyno results i can get (traction limited), and true track results at the IFO race the 23rd of this month. All results will be posted.
Until then, looks like you've gotta ASSume people are telling the truth about GT42's breaking after a few dyno pulls...

Wait I am sorry they were GT40s. I will change the post to reflect this as not to skew people.

For this '' 50whp extra to redline better than garrett claim'' ?

i dont think it would be for that... one thing is to think what MIGHT work and another is to KNOW that it works...
he just want to test it for himself i bet
1st comes the ones that try stuff then comes the ones that hear about it and then the other that misinterpret everything... so in this logic who is the wiser?

Re: Borg Warner S372 or GT 4298???? (Chris Tune)
The shaft size on the S372 is .395. What is the shaft size on the 40 and 42? Shafts don't just break but size does matter just ask a chick you know.

I call BS on the GT40 shafts breaking too! BS Please TTT provide the full story like THE motor dropped a valve and went through the exhaust.
Now I have heard of shafts breaking on some 71mm turbos due to the turbine wheel , maybe the person who had these experiences will post them up again. But a GT40, nah never heard of issues. I have had 2 of them and ran on the dyno and at the track with no issues whatsoever
TTT, I see you in every Borg Warner thread, it is good to help sell the product you sell sure BUT bad mouth another? Not cool.

Re: (Boostfed.com)
A shaft can be broken on just about any turbo all it takes it for a car to be under good amount of boost and a back fire to happen. That will break a shaft in a second on any turbo.
I would not say that shaft breakage is a big problem with any quality made turbocharger.

Exactly, that is why I said to post the whole story not just "Oh I have seen a GT40 break a shaft"
Hey I saw on TV a Bridge collapsed, I will never drive over another bridge again.

I am not saying what TTT said is not true I was just putting my 2 cents in. I know for sure it is not a common problem with any turbo unless it is over sped.

Re: Borg Warner S372 or GT 4298???? (turbodano)
I called the guys that built my turbo, and they told me they are 7.40mm for the GT40 and 8.20mm for the GT42. Not sure if that is correct or not.

7.40mm is .291 and 8.20 is .322 thats a good bit smaller than the .395 on the S372.

Re: (TTT)
TiAL and Garrett...feeling the heat!
(btw..i run TiAL/Garrett products)
Can't wait for the results tony.
Before you guys go proclaiming the diameter of the shaft has everything to do with it breaking...please find out exactly what alloy the shaft is made of. The Material's properties are just as important as the diameter of the shaft.
