Just curious. I am looking more for cars with centrifigal supercharger setups, but who is the fastest at the moment?

 

I think that would be Tory Hess aka Blown406Bird

9.29 @ 151 if memory serves

 

Damn thats definately moving. Is it a street driveable car or a trailered racecar?

 

Can speak from experience here,perfectly streetable! Doesn`t seem to mind sitting in traffic,cruises great. Just needs PLENTY of room if he gets into it (either side and in front). The feeling and sound of 8-900 hp is awesome to say the least

 

what exactly is his setup?

 

I'm curious of his setup as well.

 

Dart 406
ARF heads
mini-ram intake
Procharger F-1R
air/water cooler
solid roller
old school DFI

bought it....

 

I saw his car a few years ago at bristal it only ran 10 flat @140 then. Everyone including him went on a 30 mile trip arounf bristal and then came back a made a few runs upon there arrival back immediatly, it sounded very tame and mild but flew down the track very impresive car and super clean a true street car that realy goesss.
Any luck this past weekend Guido?

 

any more information on the car?

Size AFRs?
Size of the Cam?
Amount of Boost?
Pumped Gas?

I only ask, because I was planning to build my setup based on a buddies that ran close to the same. They seem very close to the same, just trying to figure out the differences.

 

I am curious of his cam, how much boost he runs and his compression. I didn't think an Air to Water intercooler was a good idea on the street. Anybody wanna shed some light on this?

? any pictures

 

stock typhoons have them

 

I too am curious of compression and pounds of boost...

 

i believe compression is around 9:1

dont remember what size heads, and i dont believe he'll be giving out cam specs anytime soon

The blower is pullied for its max impeller rpm (2000cfm or close to 1300hp capability)

----Air/Water intercooler on the street

Is just as street friendly as an air-air. Just more complicated and adds a little more weight, but has the ability of adding ice to the water tank at the strip to help keep IATs really low

The reason why an air/water can work on the street is because you use a separate small heat exchanger (like a mini-radiator or big tranny cooler) and run the water that comes out of the cooler to this heat exchanger and it cools it before it goes back to the water tank

make sense?

 

I'll take it he isn't running pump gas???

 

I e-mailed him. He said it is 9:1 compression and he's running mixed racegas and regular gas.

He's pretty close to a friend of mines car, guy I work with is running 20lbs of boost and 8.5:1 compression and he runs pump gas all the time.

 

What does your friends car run in the 1/4 and how much hp?

 

He last ran a 9.40 at 144 but that was with a D1SC and 14lbs of boost. He switched to a D1R, 20lbs of boost, and ported the heads.

He dynoed 700 to the rear, so we're thinking there is some problem. I e-mailed Blown406bird in an attempt that he could help us. The car continues to produce boost all the way to 7000rpm, but the peak power is at 6600. Yet the cam, intake, and heads are made to pull into the 7000 range. So we're trying to figure out why it's dying at 6600.

 

solid or hydraulic cam? rev kit?

 

Solid Roller

 

have you explored the valve train for a problem? If the valve springs are perfect for the cam application but there is one item that is a teensy bit heavier enough to change the moment of inertia then possibly a problem can occur there. A cheap and easy thing try try (if you don't already have one) is a Rev-kit. These are nice and cheap HERE

 

I called him last night. He said that was one of the first things he checked was the valvetrain.

He just sent his box and ECU back to Accel and have them check to see if anything is wrong.

Another weird thing is... he just started running the local dyno. So he gets free dyno runs. He put his car on dyno and placed the Dynos Wideband into a second bung right beside his wideband 02.

His was 1 point leaner than the dynos, yet they were side by side. Any ideas on that?

 

a full point or a tenth of a point?
