Smile Goodspeed's New GT35R twin-scroll kit

Goodspeed's New GT35R twin-scroll kit. I wanted to post my friends new 35R kit, that he just got finished. I got a ride in that beast, and HOLY CRAP, this thing spools fast and pulls really hard!!! I want to be the first to say Congrats man. IMO this kit is the perfect "daily driver" street turbo set up. The turbo he went with is a GT35R twin scroll- .78 A/R, 68mm 84 trim. This kit made 460hp on 91oct. and at 22psi. And Congrats to the guys at Goodspeed, this is an amazing build!!!

480.747.6150

More about the Goodspeed GT35R twin-scroll kit.
"Quoted from there web site" Our goal: To provide our customers a no-compromise, completely streetable turbo kit. One with extremely fast spool and a smooth power band, while still providing massive HP and torque potential. A step closer to having your cake and eating it to! For this reason we have chosen our own GT35 twin scroll configuration using a fully divided header and custom up pipe. The separate waist gates can be plumed back into the exhaust for a stealth street setup or dump for race applications. We also designed/developed a 4” cold air intake chamber to address idle and low rpm drivability issues commonly found on other kits of this nature. Best of all, this is a true bolt on kit. It works with existing APS 3.5” or 3” exhaust systems that permit the utilization of a removable catalytic converter. It will also mate up (with no modification) to the APS front mount intercooler, as well as to several other popular brands. We are also developing this kit in an 08 STI version.

That 40R kit looks amazing. I love the painted turbo and how it all flows together so nicely. Looks like it would have rolled off the assembly line that way.

I'm sorry, I don't know what Aaron paid for his kit. Give Goodspeed a call for pricing.

I'm pretty sure you're right. I don't know that much about dyno differences but this dyno in particular is the MAHA lps 3000, which is used by the auto manufacturers for long term testing.
here's a pretty informative link on how it actually reads http://forums.vwvortex.com/zerothread?id=3965266

Lets hope so, doesn't look like it's due to cams with the top end falling off after 6500.

Kit looks good except the ewg rerouting, it'd be nice to have the option of dumptubes.

FMIC routing looks much better on the 40R, but would be better off clocking the comp outlet downward and running straight to the fender IMO.

So did this car actually make 367whp. Thats what the dyno says on it.

"Wheel Power Pwheel 367.5hp"

or what does that value represent.

This was made with the APS header but we can use any header. It's just a matter of which flange we use

This is a .78 a/r on 91 oct.

This kit was build to be used with off the shelf parts. APS FMIC piping, 3" or 3.5" exhaust. Dump tube is def an option.

Actually it is 375whp, crank power is 456hp on Arizona 91. The key here is Arizona 91, it's the worst fuel.
Timing and boost levels are very conservative.

Joe what is the price tag? I already have the APS headers but I will like to know the price. Can this kit be used with a tmic (Spearco for example). I will like to stay with the top mount and add some meth. Your input will be appreciated. WIL.

I tuned this car. It made amazing power for the 91 octane fuel and the boost pressure on this dyno. Spool up over a Standard GT35R .82 is about 800 rpm better with much broader power band. With 25 psi and 100 octane I suspect this will cross over 500hp pretty easy. This is a totally stock car with a fuel pump, injectors, and turbo kit. I was impressed and with the 4 inch intake it was a pleasure to tune! Idle and drivability is like stock!
