    If they could come up with a real intercooler system it could outperform the Radix. Less heat and better efficiency. Their major problem was lack of support for GM applications and crap for customer service. My buddy has been working on a 2.6L KB on a show Corvette and has been pulling his hair out because of the lack of R&D on KBs part so he has basically had to do all of it.

    Yeah, Mark bought it and started doing the bags and bought the Timeless-6s for it. Back in the day my original wheels were the shit. But as with most wheels they got played out lol. Back then 17x11s were like :eek:

    In '93 I bought my first truck, a '90 454SS :) I ddi LTs, exhaust, k&N and a Jet 6-stage chip (remember those?) LOL

     

    dude...J

    did you work at APS for like ever! back in the day? :dunno:

     

    For like 10yrs lol

     

    I didnt drive that truck to work often though. Uusally there was the white Mustang GT or my old orange crummy '72 Chevelle lol

    Please keep us posted when you do tune. I am curious because I heard initially that the 90mm TB lowers IAT and that timing could be added. Now I understand boost may go up as much as 1 PSI all other things being equal, and am wondering if more advance is possible with more cylinder pressure.

     

    Guess we'll just have to play with it and see...  :chevy:

     

     

    I didnt hear about the 1psi gain thing and I cannot check mine because my damn boost gauge doesnt work :/ I'll definately reply back with all the data gained on the tune and what kind of #s it puts out and then obviously a vigorous track thrashing will be in order ;)

     

    As of right now I am still hitting about 101-102mph when its hot out like last night and my 60's were crap all night long with none being better than 2.19 so I'll be sure to elaborate on what we did to help defeat the Burst KR and timing issues down low that is giving me this crazy bog. I just hope this new converter does its job too.

    What kind of tuning adjustments are typically needed, going to the modified J-arm and 90mm TB? This may be my next project.  :confused:  :chevy:

     

     

    Im not totally sure because I have yet to tune for it. I just slapped it on and have been waiting for shop time to get my truck in to retune and finish my original tune lol.

     

    Mainly its idle adjustments and playing with timing form what i have read. Is tuning ever really that simple? lol

     

    I'll look into that other gauge. Maybe I can sell my lame ass Cobalt boost guage (not currently working) and get the Aeroforce unit.

    Im am very aware of the racing scene for fullsize trucks back then. In '93 I bought my first truck, a '90 454SS :) I ddi LTs, exhaust, k&N and a Jet 6-stage chip (remember those?) LOL

     

    because there didnt seem to to be much going on with racing in my area I ended up going show :( The truck ran 14.7s

    Just curious.  Why did you get rid of the STS and move on the the Radix???

     

    Long story short I was gonna put the STS on a fully built 6.0L in my RCSB and try for a solid mid 10sec truck. I built the 5.3L in the Z71 for N/A duty but ran across a great deal on the Radix and decided to toy with it and see what it could do with my high compression engine. So far its doing great.

     

    Im in the middle of my fuel cell upgrade right now so off to the parts store for some 5/8 hose :) Ohh, and why is it when you need to drill holes the damn battery is always dead and you have to charge the drill while twioddling your thumbs for the next 1/2hr+?

    With the next round of mods you'll easily be in the 12's. You have a meth kit in there?

     

    Thats what Im hoping but its not going to be super easy without cold temps. I dont know fo anyone else doing ti with my cubes and 5psi in a 4wd ext.cab so I wasnt sure it could be done till I saw my current MPH :)

     

    Im not running meth yet. I have an AlkyControl kit sitting at the shop from my old STS kit. Im trying to get around having to use it though as it clutters up the engine bay but if I end up running 12s on 5psi then I may tyry the next size pulley and then I would probably need the meth to get the full potential out of the upgrade. It would be pretty sweet to get near my STS times with only 7-8psi on the Radix and have much better driveability and durrability with this new 80E conversion.

    One trick I did to help the Radix cool down is to add a jumper on the intercooler pump power line.  I can just hook it up and let the pump (and electric fans) run while the engine is off.  It seems to take only 2 min to lower the coolant to close to ambient air temp.  Of course, there is always heat to remove from the supercharger, and more gets to it from the engine, but leaving the pump and fans running will at least assure cool intercooler coolant.

     

    I want to do that as well. I already have switches in the dash that I am not using anymore so I might as well run a wire up there. I know what you mean though. It was so bad Sat. night that I was pouring bottled water onto the ridges of the blower to help wick away heat. Lame I know but it was better than nothing. Just sucked sitting there knowing the blower and its coolant was hot and the H/E was cool.

    thanks guys. :)

     

    There is still a lot left in it with the current pulley so I'll continue to work on that and see if I can get in the 12s that way.

     

    I just bought a 3ga fuel cell to mount in the bed to replace the tiny Radix coolant reservoir and so I can fill it with tons of ice :)

     

    Im going to just launch off idle form now one and will work on the temp vs grms/cyl tables and see if I can keep the KR down as well as change out this lame converter so my 60s will come down as much as they can with the 80Es horrible 1st gear.

    I wasnt sure if you'd see this on the other forum and I know some of you were curious how this combo would work out. Well, its obviously not done yet as my TQ hasnt been changed out after we found out it was wrong, I'm running a SD tune but on a 1-bar MAP, no tuning for the 90mm TB etc.

     

    I found out some curious things about the setup. Mainly how heat tempermental it is and that my 60' is either really consistant (when I am not trying new techinques) or its drop by 2 10ths randomly.

     

    I ran mostly [email protected] 2.3 60's until we got those very long cool down periods and the temps dropped fast.

     

    Then I ran in 2wd after about an hour long cool down and got a [email protected] 2.62 60' (ok so 2wd was a bad idea).

     

    Then for the last run after another LONG cool down I ran in 4wd and launch off-idle and hit a [email protected] 2.03 60'. Talk about a difference a cool down and launching off idle made. :confused: Gonna have to check into the tuning and see if I am getting timing pulled off the line when trying to stall it up or something.

     

    Anyway, I am pretty happy with that MPH on only 5psi. Now I just have to install the new TQ converter and tuen for the 90mm TB and I'll be set. Well, until I start dreaming of the 7psi pulley :secret:

     

    Next time out I'll have a bigger fluid reservoir for the IC and lots of ice. I didnt realize how hot the fluid and the blower stay even after sitting for an hour. :banghead: I didnt have any water or ice on this trip.
