slbgtsc Posted November 9, 2010 Report Share Posted November 9, 2010 That sucks Ken, you certainly dodged a bullet. I saw a 4.6 2v after a centri blower blew up. Scared me away from going that route. I hope Paxton takes care of you so you can get the car dialed in to its max. Link to comment Share on other sites More sharing options...
ARMORINE Posted November 9, 2010 Report Share Posted November 9, 2010 Carl has the 2200 which has a max RPM limit of 60,000, if I remember correctly. He'd only run into trouble with a really tiny blower pulley. This is the blower I intend on upgrading to asap. Just waiting to hear back from Paxton. the 2200's a beast. cant wait for videos! the numbers will be bad ass. Link to comment Share on other sites More sharing options...
kahmann Posted November 12, 2010 Author Report Share Posted November 12, 2010 I confirmed with Paxton early this week that my blower is in fact maxed out. The step up ratio of a Paxton however is 3.6:1 not 4.1:1 as I thought. So that makes the RPM of the impeller a little less horrible at redline, but not by much. The tech told me I'd be better off selling the head unit outright, as they only offer a few hundred bucks for a trade in. A new 2200 head unit alone from Paxton is $2800. So I'll be shopping online for awhile I think, cuz there's no way in hell I'm paying nearly $3k for just a head unit. In the meantime, I can swap the 3.33" pulley back out for the stock 3.80" pulley and run my redline back to stock for now. This way I can get the tune fully setup finally and see what kind of numbers it puts down with 17-18 psi at around 6300 RPM's. I also need to get the Paxton 8-rib kit coming asap either way because the belt slip is unreal at high speeds. Anyway, stay tuned.. Link to comment Share on other sites More sharing options...
mywickedshelby Posted November 12, 2010 Report Share Posted November 12, 2010 Ken, following along with this thread has been an amazing ride. What ever set back you are dealt, you seem to always have a new idea. Cudos, my friend, she is well on her way to being one serious badass Shelby. Cant wait to see the finished product.

GT500-07 Posted February 5, 2011 Report Share Posted February 5, 2011 Ken, if you haven't already done so, make sure you port match the TB to the SC inlet. Link to comment Share on other sites More sharing options...
kahmann Posted February 5, 2011 Author Report Share Posted February 5, 2011 ^Thanks for the heads up. I'm planning on using my local machine shop to port my inlet elbow out, so I'll make sure to hold off until I get the new TB. Would you go with the 66mm?

I'm planning on using my local machine shop to port my inlet elbow out, so I'll make sure to hold off until I get the new TB. Would you go with the 66mm? I would if it fit. The Whipple kit for the 4.6 has a smaller bolt pattern so the 66mm won't fit. You could try an adapter plate. BBR offers one, but I like the one JDM offers with GT500TB kit. http://www.blowbyracing.com/bbrgtthboadk.html http://www.teamjdm.com/shop/product_info.php?products_id=217 Link to comment Share on other sites More sharing options...

COBRA SCOTTY Posted February 7, 2011 Report Share Posted February 7, 2011 Wow Ken !!! Totally sweet i did not know you went with a whipple. Is it a 550 kit and have you dynoed it yet and what are your numbers ? Scotty Link to comment Share on other sites More sharing options...
kahmann Posted February 7, 2011 Author Report Share Posted February 7, 2011 Thanks Scotty yeah it's the HO kit. It made 618 rwhp but was pulling timing badly. I've got the Shelby heat-ex on order, so I'm hoping that will help with the high IAT's. I'll get some more pulls done after I get the new Whipple 10 rib kit, L&M throttle body, and ported inlet installed. If I can't put down 700+ with that setup then I'm installing my meth kit.

kahmann Posted February 7, 2011 Author Report Share Posted February 7, 2011 Hey Paul can you point me to a set of ~80# flow matched injectors that will fit this Whipple without having to use spacers? I've got my 63# flow matched Siemens injectors in there now, but I'm using the FRPP spacers, which are causing an interference because of the Metco rails. The intake tube is jacked out of alignment slightly, which is restricting the coupler at the TB a bit. I've dug around high and low but I'm not finding what I need. On a side note, where did you score the KR guitar man? That thing is sweet! Link to comment Share on other sites More sharing options...

That thing is sweet! give Justin a call at JPC he should be able to help you with the injectors. we are having the same problem with the custom intake tube. I had the KR guitar custom made for Mr.Shelby's 85th birthday. He has #1 and I have #2. http://www.bolinguitars.com/bcsgallery.html Link to comment Share on other sites More sharing options...

What's the boost/pulley size? 618whp with bad timing... I'd think you should get close to 700. What does the SGT feel like with that kind of whp? It's gotta be fun!

kahmann Posted February 9, 2011 Author Report Share Posted February 9, 2011 ^I think it's a 3.375" blower pulley with a 10% OD crank pulley. Making 18-19 psi at 7k RPM. With this kind of power, it's pretty wild man. On the street, it's a whole ton more fun than it ever was with the Paxton. But on the track, it feels like I'm trying to wrestle a 1000 lb alligator on steroids. I've already got a set of Hoosiers coming, I just need to decide on a track rim. If those don't help to rope this thing in when coming out of the apexes, then I'm at a loss. Link to comment Share on other sites More sharing options...

If those don't help to rope this thing in when coming out of the apexes, then I'm at a loss. Something I figured out this summer with my car was to use a little taller gear in the corners, and use the torque to exit smooth. We have a really tight track here so coming in to a corner that I normally would use 2nd I left it in 3rd and rolled the corner more and I was able to hammer the throttle with out busting loose the rear wheels. My lap times actually got better, emabarrassed the smaller lighter cars which tend to do better on our track. They couldn't believe my shelby was staying with them. I even caught a pumped/pimped WRX. Now granted I "ony have 470hp" to the rear tires so 600+ would be even more fun to try and control. The gear change to 3.90s may help as well. The hoosiers really did a great job on my car.

kahmann Posted February 9, 2011 Author Report Share Posted February 9, 2011 ^Thanks for the input man. You're absolutely right about gear selection. It took me a few sessions at the Vegas Bash to realize that I was going to 2nd gear unnecessarily through a couple of the turns. With the Paxton, it would have been a no brainer. With the Whipple, however, I made quicker lap times by leaving it in 3rd and not breaking the rears loose too badly out of the apexes. I'll let ya know how I like the 3.90's. They just showed up yesterday. Link to comment Share on other sites More sharing options...
