Nice comparison.
At around 4500/4600rpm they are the same so the S366 is not really that lazy.

What exhaust housing was on both turbos?

What exactly is a S366 91-79? What do the numbers mean?

 

My s366 is an undivided .91. Ill have to ask my buddy what his AR Is.. To be honest with you I'm not sure what 91-79 is. I think* 91 is the AR but not sure what the 79 is. All I know is it what on the card that that came with it Lol.

 

=Lagtime;903459291 is the exducer size in mm of the compressor, 79 is the inducer size of the turbine in mm.

Also, if you have BW box unit (not a BEP), the .91 AR is divided, the .88 is open.

Your right, my mistake it is a .88.

 

The 482whp would be around 545whp on a dynojet.

The 515whp would be around 582whp on a dynojet.

See my dyno comparision calculator at : http://mkiv.supras.org.nz/dyno.htm

 

Nice calculator.
I do disagree with using this though because we dont know what weight they might have put into the dyno or what other things might have been adjusted to get the reading. Just by using a different weight you can get different results. If it was shootout mode then I believe its a better reading which is not tampered with.

Jose946speed thanks for the clarification on the wheels. I thought the 79 was a different one from the 80. Good to know its the same.

 

Nice comparison.

 

Interesting. My calculator says 466whp is around 527whp on a dynojet, so is perhaps estimating a bit on the low side for your dyno dynamics mode as my calculator is based on shoot 6 mode.

We use the dyno dynamics a lot here in NZ. In a month or so I'll dyno my car on both dynos (once I finish some planned changes) and post a comparison on this forum.

 

Where are there DD here, 360rwkw? Admittedly I live in Welly so might be missing out on some places up in Auckland but I'm only aware of maybe one or two - seems predominately Dynapack and DynoTorque (which seem to read more or less like Dynojet from what I've seen). I've been curious about putting a car on a DD at some point.

Really interesting comparison - the other interesting thing is I've seen an EFR9180 versus S300SX 91-79 and the EFR deals to it in spool and power, can't wait until someone winds the boost up on an EFR9180 on good fuel - good chance it could become an ultimate weapon for 800+whp setups.

 

There are 4 Dyno Dynamics dynos in Auckland, 2 in Christchurch, 1 in New Plymouth that I know of, but probably not many elsewhere as you mention. Much more common in Aussie of course.

I've used Gavin's Dyno Dynamics at Hi-Velocity for many years but have recently switched to using the DynoTorque at Torque Perfromance. The DynoTorque read extremely close to the Dyno Dynamics dyno from both myself and other friends dyno sheet comparisons between the two dyno types.

 

very nice! ive had a 366 a few years ago and went a different setup, now changing it again ive been loosing hair trying to decide if i want the billet 366 or a 6765/6766. I think since im already setup for the borg i will just stick with it seeing this.

 

i dunno thats a good bit lazier 3-400rpms. not to mention its not the 67/66 either. But im sure your b/w will last 100k miles compared to the 10k of the pte. Id prefer to see it overlaid with the same rpm scaling. and high boost/race fuel see which really shines over the other. Either way thanks for sharing, and let us know how much it improves with the new wheel.

 

nice. awaiting results of what the 6765 A/R is.

 

Here's as close as an overlay as I could get guys. All the RPM points lineup now. Your car has an odd torque dip right in the meat of the powerband. Any ideas on the cause?

 

Thanks for the overlay. The only thing I can think of is maybe its the way the boost controller is set up.

 

also looks like te 6765 dyno was started maybe 500 rpm sooner, might of helped a little.

 

Nice comparison! In for the billet results

 

Ok, here is a bit of an update on the red car with the 6765.

Here is the car at the same boost level + GSC S1 and valve train. For some reason it saw less torque?

Here is the car at 27 PSI on E85:

 

less torque with cams is usually normal, with cams you are typically shifting where the power goes. shift up and lose torque gain hps. losing torque isnt necessarily a bad thing either, as it can help with traction. keep in mind the way the dyno takes measurements 5250 tq and hp always meet.

 

Wow those cams make a huge diff

Would love to see a the same setup with the s366

 

Me too, but lets talk about the real things: price/hp >precision 67/65 is it more costly/reliable than the BW? I guess the precision is cheaper(price)~1200$? and the BW 1500$?

 

Where the hell did you buy an off the shelf BW for $1500? Those are under $800 pretty much anywhere.

Who's doing your wheel install on the turbo? Was the price 270$ for the billet wheel sending in your old turbo? Or is there labor ontop of that?

 

The boost lab does it. Being that the billet wheel is off there new line of turbos. I expect to see good reaults n spool too. I'm debating on sending mine out now or waiting till spring after I get my car on a dyno to do another before an after. It will obviously be the second one for the community but good to know for my personal car for me.

 

Link???

Also my first question remains, is 270$ the price for the billet wheel installed, or is that just the wheel itself, what's turnaround time look like?

 

^^^ this

 

+1

 

For anyone that is interested, here is before and after with the GSC S1 cams for the red car.

Blue is stock cams

Red is GSC S1

 

wow nice numbers and great job comparing the two turbos... very interesting to say the least

 

Hrm

 

Same here, and I want to say this again, so I don't cause drama, maybe he did? All I know is these wheel do appear to be identical in every way.

 

looks identical

 

There will always be people to make there own parts or copying maybe changing little things calling it there's. At the end of the day who know's who was the first person to make it, but its good to see more than one doing it as it keeps pricing down with competition imo
