there is alot of FI going on around here now, anychance we can get a list of peoples ET reductions with a blower only change? it probably wont be a very consistant list since most people dont start with a blower on a stock vehicle and then there is the traction issue but we can try. all i hear anymore is RADIX, RADIX, RADIX, so lets see some numbers.


stock 99 ext cab 4wd... 16.7
add whipple at 6psi.... 15.3 (1.4sec reduction)
then add everything else, 6.0, headers, tuning, efans, posi, stall, 8psi with good gas... 12.77


whos next?

 

00 Siverado 5.3 RC/SB

Never timed it stock

Radix only 13.2 @ 103 @ 8 psi (stock pulley)

Have added some mods since, I am expecting 12's

BTW, RADIX RADIX RADIX!


Sorry Parish, I had to do it!

 

got to admit, that is a nice number with radix only

 

And you BY FAR have the fastest 4x4 I have EVER seen!


What are you working on now?

 

03 Silverado SS weighs about 5300 lbs without the driver.
15.3 stock
13.9 with Radix. Still some room for improvment by quicking the shifts.

 

1999 GMC SCSB Stepside with Gibson Shorty Headers/exhaust, Jet Intake/Chip ran:
15.6 @ 88 with a 2.4 60'

With Whipple, Gibson headers/exhaust, stock air box ran, stock tuning and shift points:
14.4 @ 95 with a 2.25 60' (1.2 second reduction, +7mph)

Probably could have gotten a low 14 second slip with some more practice.

Never ran it with the built trans and the Vig...but it should be capable of mid 13's.

Tahoe ASM headers,electric fans,underdrive pulley,HPP3 and Yank 3000,15.2.Add Radix and change crank pulley back to stock 13.285.

 

saving up for somehting like this, gunna run HARD





wow, 2full sec in the hoe, is that with stock boost? i can see the radix is kicking ***. where are the ati numbers?

 

Parish, I was thinking about that Radix and your concerns about it feeding a low comp 408. I have read a few bits regarding people porting parts of their Whipples over on FSC.com and gaining pretty good power gains. Basically flowing more air at the same boost level...like Flems LS6 headed Burban with a Radix.

Would not porting the compressor yield a higher flow rating?

Could you stick a Kenne Bell twin screw compressor on the Radix base like the blown Cobra guys do? I'd assume only the area where the TB bolts up to the back of the compressor would be changed from the Ford to the GM one.

 

That was with 7 lbs boost,I've added 4 lbs more boost and 1.85 rockerarms since that run.I've beaten several Lightnings,a 03 SVT Mustang,a 03 M3 BMW and a 03 M5 BMW on the street,but have'nt made it back to the track yet.I also have 2.75"pulley I have'nt tried yet.
