Damn good power for that boost and stock ports!

 

So we finally got the manifold all sorted out and actually made a pull. Boost controller is still not hooked up so its running off the spring only, 17psi. also using E70 only. Made 497rwhp at about 8200. Still have some more bugs to work out, 4 1600's for the primaries is not making the car to happy on the bottom end but she screams up top. Once we get all the bugs worked out well get some 25psi pulls and see what she'll do and hopefully stay together. Car feels completely different to drive compared to the 35r but it will just take some getting used too. Heres a little vid.. car is extremely loud in person.

Dem that bitch sounds nice n loud... Good job

Nice numbers for a stock port @ 17psi Can't wait to see what it will do with more tuning & boost

 

Congrats guys, sounds freaking great!

 

awesome!

 

That poor turbocharger is confused at only 17psi......crank it up fackers!

Isnt that wideband O2 sensor a little too close to the turbo for longevity?

 

Whats the correction factor on your dyno Anthony?

 

I watch this video then stare at the S475 sitting on the floor next to the computer and the FD shell outside the window....and I HATE YOU GUYS!

Seriously, think you can sneak it onto the track again with the new turbo for one hot pass?

 

sounds like it hits full boost rather quickly considering the size of that thing. when you getting 17psi?

 

Ray had that same turbo on one his cars and it outspooled my GT42R duall ballbearing. Same porting too. Quite impressive turbo for the money.

 

I've done alot of comparisons with my dyno and local dynojets and have come up with 15% as my correction.

So my dyno is right on par with a dynojet.. Also with the weather corrections yesterday the dyno was pulling about 9% away so the actual uncorrected number would be higher by 9% if i was to turn off the weather corrections..

 

Good Stuff!

 

More boost yet?

 

took the 1600s out yesterday and put in 8 1000cc instead. We retuned and dynoed the car made 503.1 at 17psi. so we cracked 500 with my low boost and my "pump gas" setting which is really cool at 1.97 a gallon E70.

Driveability is way better now and behaves more like a street car. Ill be daily driving it for a few more days need to hook up the boost control and boost gauge still, my exhuast is smashing against my diff brace on shifts so need to work that out as well.. Im saving my pennies for a 55g drum of race fuel now so in the next week or two ill hit the dyno again with the boost control hooked up and more boost since we really werent ready until this point.

 

time to update that sig. lol

 

Man there's alot of crickets in here..

 

Well bring the noise

 

Hoes the car with that turbo on the street? What rpm you getting 17 psi by? how does it come on? breaking the tires loose or gradual? i have a t78 now and wanted to change to one of the BW turbos, maybe a smaller variant that can still work with my T78/T4 divided manifold. But if the is 475 is streetable the may consider it.

 

still on 8x1000cc?

 

yep. I might switch to 4 x 1000 and 4 x 1600 in the near future if I need more fuel.

 

more boost?

8x1000cc was enough for 709rwhp?

 

Yes, my friend....but that was at 32psi. This turbo works "best" at 38-40psi

any update?

 

Car has been running with 28~29lbs of boost for the past few months. It has gone 9.85, 9.99, 9.9x at that boost level. Maybe when it gets a bit warmer out we will turn the boost up to 35 or so and run it again. But for right now it's good where it is..
