A Merry Christmas indeed. Nice work Steve. I've become quite fond of you frequently "outdoing yourself" -R
Looks like bad things happened to the tranny. http://www.lchevere.com/BJB/BJB.wmv http://www.lchevere.com/BJB/DSC02479.JPG http://www.lchevere.com/BJB/DSC02481.JPG
You have got to be kidding me. How the fuck did that happen. Something was well and truly not right there. Brian mate I really feel for you bud. That is just bad bad luck. How's the engine, how did it happen and any idea why?
It was a GM 4L85E trans with TCI control. I believe (if I remember correctly) it was done at a cost of approx $15K (build just on the trans alone). Whoever built that really has some explaining to do. They obviously don't know transmissions very well. I just feel so so sorry for Bill. I have followed this build of his from day one and its really dissapointing.
I agree Mate. And since you mentioned the tranny, I believe you are correct. Thanks. Wonder if the transfer case let loose as well?
This didn't even happen on the track. The hood was up. Here is Builder Bill's Quote High speed Hell...it was not even moving! Next to the trailer. I was standing right next to the passenger door that contained the shrapnel and DynoSteve was in the driver seat. At first I thought it was the supercharger that let loose because it was so friggen loud, but as i looked at my feet I saw planetary gear pieces etc....all on fire. As most realize, tranny fluid is pretty Damn flammable. I saw Steve and he pulled the cable on the fire suppression system that unfortunately did no good for this fire. He had a time getting out with the roll bar and burnt his hand. Tonight I'll bet he finds some other ouches. Someone was looking out for Steve because if the tranny let loose 1/3 of one revolution earlier, the shrapnel would have come through the driver side. BJB was about a half hour from the disaster on his way to the track. That was a tough phone call for Steve to make. BJB takes things in stride though. I don't see myself taking it nearly as well as BJB. Bill
holy crap that BJB's jeep literally took a shit! I don't give a flying fuck who is wrong and where, how that thing dumped is impressive...
CRAP man I am so sorry I need to buy a trans I dont want this to happen to me. So you where just idleing sitting there and BOOM
There is no way, something else must have been going on, I mean wasn't this being run up on the dyno 2 days ago showing 920hp. Would have thought it would let go then. As for your trans, just ensure a reputable builder gets it done for you. I am running a 4L80 T400 in mine and I have no doubts it will be ok. Southern also do a proven NAG1 for high hp.
The trans cost me $4500 and included the following: Full manual setup 2000hp rated (yes more than I will need) HD 300m input shaft Setup for nitrous (clutches/material/planetary etc) Trans Brake Plus what ever else went into it On top of that I had to get the drive plate (flex plate) modified or fabricated to suit this setup (not sure exactly which way they went but is done). Bellhousing and adapter plate to suit conversion (done inhouse). Shift and cables 2500 high stall (loose) to suit engine and blower configuration. Tailshaft modified. The computer has a setting that can switch off the transmission function trhough CMR software. All it does is tells the computer not to look for a signal from the trans. This does not affect any other function. The rest has been wiired into the OEM system and all EVIC, cruise and functions will work just as they did if running the NAG1. It wasn't a straight drop in and go but wasn't to hard for them to do (as they told me). The challenging part is/was the wiring. All up including install it would have cost me about the same a SHR NAG1. The guy that built this T400 for HP/F - Me has built it to a specification requested which is better suited my cars needs. He knows the power rating of what he has built as he has done plenty like this that are tried and tested (and by no means am I implying SHR transmissions are not, they are definitely the goods from all accounts - AND THEY DROP STRAIGHT IN TOO). Depending on what you are wanting and how you will be using the car should be the deciding factor for which one you choose. If your car is to be a daily driver, this would not be a comfortable drive (not saying you can't though, will definitely handle it) just not refined. The SHR unit is a great trans from what I have read and should be ok, speak to Eddie or Bill (Builder). My only concern is that you will still be somewhat governed by the TCM where as my setup is not.
Man that really sucks bro! Hope your luck gets better......i`m still trying to stomach 15K for the tranny!
There is no way that was only running a 100 shot and hitting 920hp. Not doubting the numbers but +300hp over last know dyno reading, no way. Running at 15psi no gas, well here is the sheet from earlier in the year from SHR. Unless some big mods were done, there is no way it was only a 100 shot and 4psi (extra). And knowing Steve, he loves the gas and there is no way he would have run this up with only a 100 shot flowing.
Looks like they had a bad day. Glad everyones ok! Evidently the entire tranni exploded into pieces. http://www.lchevere.com/BJB/BJB.wmv
I don't think that is from BJB's Jeep. It was never at SHR, Eddie actually closed the shop and came to the Jeep to tune it for the Pump Gas Drags (Yes Eddie from SHR did tune this truck for the Pump Gas Drags back in May, I believe in giving credit where credit is due). It made 670rwhp on Pump gas with a really conservative tune due to the fresh build and all the limp mode issues. This is still the same basic configuration (with some tweaks to the braketry for reliability) but on 19psi, C16 race fuel, more timing, a leaner boost only tune and the nitrous system jetted for a 100 shot. No numbers games are being played here. The events from yesterday are incredible. I'm certainly glad everyone is OK. I couldn't make the trip due to family obligations but had I been there, I would most likely have been in that passenger seat. Hell, if Brian hadn't gotten a speeding ticket on his way down, he could have been sitting there too! It sucks that this happened. Nobody would have ever expected this. I've never seen a trans come apart like that with the vehicle not moving or launching. I don't know the details and probably won't until the trans builder gets a chance to look over the pieces tomorrow and determine what happened. Take this as a reminder that when you are pushing things this far, this kind of stuff can happen. I've been in many 9 second street cars that never even had a rollbar, let alone a scattershield or trans blanket. We sometimes get so wrapped up in making a car go fast that we forget about the safety aspects of it. Again, Glad everyone is OK and I'm sure BJB will have it back bigger and badder then ever.
My apologies the dates were wrong, yes that dyno sheet was from back in May. As I mentioned though there is no way that reading was shown with only a 100 shot. Its running a dual fogger system if I remember correctly and there is no way Steve would stop at a single 100 shot. Whats more show me where its is running a leaner boost only tune. 11.3 down to 10.5 across the board AF/R-1 is shown on that sheet Steve posted which doesn't indicate a lean tune for boost but a rich tune for a big shot of Nitrous. Check out the previous dyno sheet I posted. SHR was at around the high 11's/mid 12's no nitrous tune. Summary, your not going to make an extra 260hp at the tyres (and didn't you mention a 25% drive train loss, or someone did) with the addition of another 4psi, richer tune and a 100 shot of gas. C16 race fuel allows you to run a leaner tune but that is not the case here. Am I doubting the figure achieved, hell no, but how it got that figure, yes I am. I also know Steve pretty well and heres why I doubt a 100 shot only was used. He is dying to be the first to hit 1000+rwhp whether its his car, a customers, or just being involved with the tune or build. If Steve was so close to hitting a 1000hp at the treads with only a 100 shot used as stated, I promise you that he would have upped the shot of gas until he hit the magic mark. The dyno sheet he would have posted on the front page would not of been the one there now BUT one showing 1000+ hp at the tires. But if you still say it was as it was, no probs I won't say anymore about it, hell I wasn't even there.
