We are pleased to annouce that Speed Force Racing(SFR) will be attending the upcoming turbo shootout on the 16th for SportZ magazine.Every turbocharger system offered for the Z and G will be tested including our own twin-turbo system.We are using Tinmans G35 to represent us.This car is probably going to be the only automatic tested but we are looking forward to it because psi for psi of boost, our system will make the most power

 

Look forward to going head to head....Best of luck to everyone....

 

Nice! Should be a good shootout.

 

SFR, to be confused with SSR.

 

Same company...SFR builds the kits...SSR just sells them..

 

Actually it is two different companies.SFR is in San Diego and SSR is in Arizonia.We both sell the turbo kits.

 

april 16th, or may 16th?

 

May 16th I believe

 

Eh...not what I would want to see. I'd want to see the same Z get every kit installed and get someplace like SGP Racing, CJ-Motorsports, Altered Atmosphere, and/or GRD Performance to install and tune each kit, that would give consistent numbers. PSI to PSI is going to vary from turbocharger to turbocharger...so even if SFR dyno's the highest...what does it prove?

 

How will your kit make the most power?
Are your turbo's more efficient,fuel delivery system better,better engine management,or just a really good tune?
At the last dyno day,Tinman made numbers that were decent for the psi he was running,nothing extrordinary.
You guys dont pull any timing,right?
So what A/F ratios are you tuning the kit to?

I'm building my motor & taking this Stillen SC to its limits.If that isn't enough,I'll be buying a TT.I had APS in mind but I'm still deciding.
Could you compare your kit to the APS?

 

Unfortunately that is not going to happen.If each car is run at the same boost pressure then the testing should be fair.

 

[QUOTE=weslutes]How will your kit make the most power?

It is more then that.The headers we are using are much better then any of the log manifolds that are being offered by everyone else.The turbos we are using are bigger and very efficient for the intended application. We use two external wastegate instead of two internal wastegates which helps control boost much better and more efficiently.The stainbless downpipe and dumptubes are much better then the cast iron that every other company is using.The aluminum charge piping is much better at dissipating heat then stainless and mild steel piping.The Spearco intercoolers are some of the best cores on the market.So these are just some of the things that make our kit superior to the other kits.

Yes but he was only running like 3-4 psi and we had not tuned his car.

It depoends on how much boost we are running.Anything more then 6.5 psi and the timing is retarded.


So what A/F ratios are you tuning the kit to?



11.8 to 1 typically.

We have had a chance to mess with the stillen stuff and if you are looking for more then 330-340 at the wheels then start thinking about a twin turbo system.At 340 the Stillen system is maxed out and you will be running alot of boost to even get to that level..


Could you compare your kit to the APS?


Here is a comparison that is easy to read and understand:

SFR APS
Two T-3 turbos two t-28 turbos
Two external wastegates two internal wastegates
SS equal length headers cast log manifolds
SS downpipes and WG dump cast iron downpipes
Spearco intercooler ??? intercooler
Aluminum charge piping stainless charge piping
Split Second controller Unichip controller
440cc injectors ??? injectors
HKS Sequential blow-off APS blow-off

 

[QUOTE=TurboTim]Don't forget
SSR/SFR | APS
Life-Time Warranty | ??? Warranty
Made in the USA | Made ???
Stateside customer service | ....

 

APS uses Garrett GT2535R turbo's (exhaust is GT35, intake is GT25).
APS intercooler.
And I think they use 440cc injectors as well, but they have a return fuel system.
And the Unichip controls a lot more than the split second controller.

 

Well, if this is on stock motors I think the shootout should mostly be based on features, cost, sound/looks, performance, etc.

If it's based on cars with built motors, then it's just tuning.

Either way, I don't see the point in a "shootout" since there's so many variables.

 

APS has a warranty, I can't remember for how many miles though, Peter's mentioned it before.
APS is made in Australia.
State-side customer service, sometimes, not anyone from APS all year round, they send someone sometimes over here, even though i'm pretty sure you wouldn't have a problem getting in touch with Peter on here.

 

thanks for the comparison.
What else do I need with your kit to make more than 10-12 lbs? Or is it able to already?
This SC will make at least 380 with 10 lbs.I also have n2o.So it should be fun for a while.I'll have to see

 

so will every car tested have the exact same supporting mods (IE test pipes, exhaust diameter, pullies, intake manifolds etc etc)?
