finally have some dyno results from today. Tim flew down from Chicago and spent time on my car. On pump gas at 15 psi the dyno showed 650 rwhp and 650 ft. lbs. torque. Tim felt there is perhaps another maximim of 25 rwhp left in her but I know this engine can do better. So Mr. Norms and I agreed to make some changes. Seems like this car has had plenty of changes already, but more in store. The hurst short throw is out, unneeded gauges are out, a water/meth spray is in and a new KB 3.6L with a 150mm TB is in. The N2O injection and cooling are both still in. So will be down for a short time as I agreed to let my car be used for some testing before we finish the build. I will post as more developes. We will be meeting next Monday to finalize this plan. Oh yeah, 15 in of vacumn at idle!
The only thing we would change is th sc to the 3.6L, the 150mm TB, and water/methanol for octane jump. The car is now pretty much complete. We are switching the short throw Hurst shifter back to stock as well. I think everyone will also like the gauge changes we made already. Hope to post pictures tomorrow when I visit with Mr. Norms.
holy beefy twinscrew!!!!! thats a big blower! Keep it up Rubbel! you really know how to make us feel as anxious as you are LOL...
Cam - I traded my whipple for some body repairs and painting. Gave away a 5" tach. Tell me what you want and if I have it it is yours!!
OK here's my first video attempt: http://s956.photobucket.com/albums/...Challenger/?action=view¤t=INSANE426.flv and a few pics too!
Wow! Did anyone see that idler pulley flex when he stabbed the gas? It's supposed to do that, right? Les
Jim, depending on your IAT's, type of fuel (91 octane) and a couple other tid bits. That's about right on the HP. What where you expecting??. I would bet that the intercooler could use a upgrade. But not having worked with da vipple, it's a shot in the dark. The 2.8KB is right there in standard form. Now go 3.6, add an ice box, throw some fuel and boost at it and now you're talking some serious power. I know the KB unit is the most efficient unit out there right now. But it'd be fun to see what a Whipple or Techco could do with the same treatment.
Cam - really did not know what we would get, but Tim felt the air restriction was the limiting factor. We will be installing a 2.8KB with 150mm TB and running as a comparison to the whipple. Will post the results as soon as we can get this done. The next step is to put on a 3.6LC KB unit. This is a rare commodity right now. #1 is on Tims KB racecar, #2 is promised to an employee, and I'm in line for #3. We will also post those results to show difference in all three sc units. We will add water/meth so we can be running close to C16 all the time and make one set-up for the street that's comfortable to drive, and maybe 20-25 psi for the track with nitrous spraybar to heat exchanger and a shot into TB as well in a second all out set-up. The Trinity makes multi tunes a snap. Basically just change a pulley and good to go. The whipple idled well and ran very quiet but we want to see what we might be leaving on the table with this motor. I meant what I said about unused parts!!
The air restriction is a MAJOR factor. You'll find that the 2.8 with a stock 80 is right there on the numbers you have. That damn 150 is the ticket. There is another 3.6 out there running right now. At 22-23, C-16 and a few bells and whistles tossed in is making 930+ on a 420 something. Your're going to run into a issue at higher boost levels, but not with the blower it's self. I'm sure Tim and the crew will take good care of you on that one. Myself, but not having any good info on the Whipple would build a new plenum for it and run a 150. It'll never make what the 3.6 will, but I bet with the right stuff as mentioned above would net somewhere in the mid 8's. Oh BTW, I built a bad to the bone set up for the intercooler on a Chally this past week. It looks stock, but opened up the lower valance to the full height. Please let me know what you have left. I have a major build going on that I might be able to sell those for you.
Here's one with 93 octane and just 8 psi, no ice, no high octane. Guessing that with tturbo, 15 psi and some 93 (versus that 91), that more would be instore, and so on and so forth as charge gets cooler and octane gets higher. Hear those KB's love Torco on the dyno, if you're thinking of switching to one. Good to see it's running and headed in the right direction.
