Competition Turbos

[OT-OF-HERE!!]

Can someone provide a comparison to each of the following:



S300

S400

S500



Pls use well known turbos for comparisons. Tks

s500 I know nothing about, but it would have to be a 4500+ rpm setup to get that lit, or a set of twins. It is tough to compare cause you can get an s300 that has a larger compressor than the smaller s400's. What exact info are you wanting?

 

[jwilliams3]

Phat shaft (and super and SB) And HTT 62, 64, 66 = S300

High Tech Turbo HTB2 and 71 Series= S300

TAD B1's=S300



TAD B2=S400 (75mm inducer @ compressor) OEM part number 171702





Alot of good info on S300 from Borg Warner:

I recently taked with ATS and they are putting together compounds using the turbos I sought info on. I needed to get an idea of what levels these turbos were at to see if they matched my needs. That info you provided was a help,... tks.

BD has made there twins for years with those turbo's you mentioned involved, so ats should not have a issue making them work well.

So with all those well known turbo's comparing to a S300 how does say an Aurora500 come into that? or is that based off a Borg Warner also?

A5k is based off of a k31. The old triple K which was purchased by Borg Warner.

 

[jwilliams3]

Well if a GT42 and an S400 got married and had a kid it would be a K31 :-laf

 

[zstroken]

I guess it depends on if both of them had the little recessive gene :-laf . Actually the original K31 isn't that great of a charger. The ones you want are the ones with the extended tip compressor wheel. I wouldn't necessarily say that k31 is a better charger. I saw a 71mm GT42 put 30 feet on several guys running A5K's at the friday pull at scheid. Their are many variants of s400. I think you can get from from a around a 2. 5" inducer to at least 3"

 

[jwilliams3]

Hey now there Dan! lets keep this civil. For the publics information that same truck was 5 feet behind an Aurora 5000 a week before the Scheid pull.

I wont name names to protect the innocent... . :-laf



The only K31 I would consider is the Borg Warner Peformance K31 (PN 172743) with extended tip and forged billet milled compressor wheel.

 

[zstroken]

Who mentioned names?? That is the beauty of the internet, just telling one situation and forget about the one you don't like!! Yea I remember the gaston pull, but wasn't that a rookie driver in that truck??

 

[jwilliams3]

Rookie driver my arse! He put 20' on you!! :-laf :--)

 

[zstroken]

LOL true true, but I can think of a pull where the veteran only put about 2 feet on me and I think at scheid the following day he only put 2 or 3 also. The key is consistency and I don't have it with my truck. One day it runs good, the next time, it doesn't. I was suffering from PCM problems at gaston, hence the accidental shifting to drive followed by the abrupt down shift to second and about 4000 rpm.

Big swings in power

I don't know if this would help you or not but a recent investigation I went through to discover what can cause huge swings of power from run to run or day to day came up with two things. A bad relief valve and a faulty fca valve or faulty installation of the fca valve.

On a 12V???

You don't have your sig info displayed
