Rcklessdriver has gone into the 10's on a D44, I believe. I think it all depends on how you "hit" it. IIRC, you've got an auto....I'd think the rear should be alright.

 

I need a MT ET Street R 255x60x15

 

The case on the C3 D44 is a lot weaker than a C4 D44 if I recall. I seem to recall it falling more in line with the dana 36 as far as actual case reinforcements/rigidity.

 

Ah. Well that would change things quite a lot.

 

Yep, the way the batwing integrates with the diff is an issue of strength even though it is a dana44. The later dana44 on the C4 is a bit different, but the C3 diff is a bit better than the 84 dana36. We blew the entire rear end out of Jim's 84 at the track one night and replaced it with a C4 dana44 from I think it was from a 95/96? Anyway, no issues after that and it also had a 3.45 gear if I remember correctly.

 

just got off the phone. They have a few sizes but not that one. Sorry.

 

Thanks, yeah they are VERY rare right now to find.

 

Honestly you me that's surprising. Seems to be a common size.

 

I feel I'm being dragged into a competition here
I honestly don't care if I have the fastest car or not. If someone beats me, that's a win for all of us who persist with this platform
I'm more interested in beating the clock than beating other guys.


My 'new' trans I assembled 10 or 12 years ago is now in the car and working great! (for the 10 miles it's travelled thus far!)
I still have to tune the shift points better and get a few more miles on it to be confident it's not going to fail but so far it has literally transformed the car and I know I'll enjoy driving it more than before with the harsh shifting clunk old 27 spline (no aux. valvebody) 700r4. The shifts are great and the line pressure is doing what it should when driving so it shouldn't die immediately.
Having an PCM tuneable trans is amazing, I should have installed it y-e-a-r-s ago. No more clunking the u-joints when putting it in gear, nice smooth ,crisp shifts at part throttle, upshifts and kickdown shifts exactly where I want them. It's amazing what difference one decade newer tech makes

I still can't go WOT as it literally kicks down a gear and smokes the rears at any speed because the tyres are soooo bad, so replacing those is the next job so I can tune WOT shifts.

Once I'm sure the transmission is solid, I'll likely take it to the track to see if the new converter can take a tenth off the 60' and two at the big end!

 

Do you think you can fit the 300s under the rear because I just picked up 10 of them (it’s a long story). 40 tread wear they are sticky not sure whether that’s good or bad for the drags. TBH I don’t think they will fit with the offset I have on those wheels or maybe any offset.

 

I hope I didn't contribute to that....I just want you, bucc and 84 4+3 to go as FAST as your combos can possible go, for the benefit of the CFI platform....since I can't contribute any more. Beat the clock...I say! Run it to the absolute bottom number!

 

I'm just curious how far a stock bottom end will go lol. Based on the metal in the oil... I am about there so time to test sooner or later.

 

So I've been thinking about this. The original claim was 30hp on a stock engine correct? Well... If you take a look at where the stock intake is about tapped out, we will say 4400 rpms, it makes ~270hp. Then the renegade makes about 300hp at that same spot. I think it is a fair deduction that claim could be true being you wouldn't be seeing the same air flow on the engine with the stock components until maybe 4800 or 5000 rpms... I know with the renegade my stock top end was ~5100 rpm and putting the stock intake back on it peaked around 4500 before it really fell flat.

Just another data point but if I could find some flow data on 624 heads we could surmise the air flow requirements at the rpms for the stock and renegade on the current mill and see how it compares on the original components...

 

There's flow data for the stock heads on Stan Weiss's site:

Funny I was just looking at some of the old posts on Grumpy's performance garage yesterday. They tested a Renegade when they came out on a stock engine and claimed 32hp.

 

 

I don’t think you should be sitting back and eating pop corn

 

LMAO...Well, I have nothing else to do but eat popcorn since I SILL CAN'T find a DR tire. I'm almost incline to buy slicks if I can find the right size at this point.

 

If you snag a plane ticket I'll feed you, give you a full tank of gas, and let you let mine eat until something breaks.

 

you should be out looking for a foundry. I hear they have good ones in Mexico. Adiós gringo
