Re: Project LQ4 - V8 S10 - Minor details

Better get some meats on that thing, that stall will snap your neck launching with boost!
 
Re: Project LQ4 - V8 S10 - Minor details

my truck has a higher stall, its from a yukon or something like that. it could be the tune, but the truck stalls after I take it out of reverse sometimes.
 
Re: Project LQ4 - V8 S10 - Minor details

I dont think you know what a stall is marshal LOL, your on the wrong page.
 
Re: Project LQ4 - V8 S10 - Ain't dead yet!

I had a car with a three grand converter and tall gears, it was like accelerating in a jet drive boat. Light vehicle, ample displacement, turbo... all these reduce the need for higher stall speed. If you don't have the final drive ratio to suit, forget it. If you do... ask yourself why you want to bang your launch harder on street tires. JMHO
 
Re: Project LQ4 - V8 S10 - Minor details

I'd think the planned turbos have a bit to do with it. My thoughts are in the area of : What type of rpm will it take to get them spooled up if you are trying to boost off the line etc? , Will it make daily driving difficult to do without having to play the pedal like a piano to keep things reasonable w/o a harsh hit?
 


Re: Project LQ4 - V8 S10 - Minor details

I have a feeling that daily driving will not be a consideration once boost is applied...

That's why he's building the K10. The S10 cab is smaller than the K10, and I bet it feels much more comfortable in the K10. Plus the K10 looks better.

Hell, even the 2500 is most likely more comfortable than the S10.
 
Re: Project LQ4 - V8 S10 - Minor details

i did some reading up on higher stall speed for my camaro. seems every one whos has one loves it. most say these cars should have come factory with a 2500-2800 at min. and they dont tend to rev to much or hold a to much higher rpm then stock.

they all love that circle D TC tho. they have a dual clutch in the tc or something like that for my cars 6 speed tranny. not sure if that available for your tranny.

needless to say, when mine gets cam'ed its getting a 3000 stall at the same time, or soon after. its also getting boosted.
 
Re: Project LQ4 - V8 S10 - Minor details

Wish I understood torque converts better. I haven't really researched them ever. So a higher stall is better when you have more power, but not too high so you have some control over wheel spin? I'm such a noob...
 
Re: Project LQ4 - V8 S10 - Minor details

most performance cams dont make the start of their power curve till 2500 rpm or more, so the higher stall will put you at or into the start of the engines power right off the line. aka makes it much faster off the line. some of the threads i found guys who cut many tenths off their 60 foot times.
 
Re: Project LQ4 - V8 S10 - Minor details

Ordered the torque converter.

10% off the base price plus $50 off the billet cover. The converter that would have cost $749.99 yesterday put me at $639.10 to my door today. Now the waiting begins...
 


Re: Project LQ4 - V8 S10 - Minor details

Yes!

Who wants to help put it in?
 
Re: Project LQ4 - V8 S10 - Minor details

it hardly snows here before jan-feb these days, but it dropped 3-5 here this week. almost melted......
 


Re: Project LQ4 - V8 S10 - Minor details

In reference to post #270...

Hindsight being 2020, I may have gotten a little too aggressive with the accumulator valve spring. Should have gone with the Trans-Go recommended setup. The shifts were to "abrupt" for my liking. So this weekends task was to re-spring the accumulator valve. My plan was to drop the pan, pull the roll pin, pull the end plug, slide the extra spring in and reassemble. That was the plan...

I ended up not being able to pull the roll pin with the VB in place, so I had to pull the VB it and do it on the bench:

What should have been a 2 hour easy ordeal turned into a six hour fiasko. Six hours you say? Yes, six hours... when you neglect to hook up the manual valve. Do it all over again to get that manual valve hooked up. Anything worth doing is worth doing twice I say! Anyhow, I got it all put back together (thank you green goo for holding the check ball in place!) and took it for a test drive. Shifts are much better. Still very firm but it doesn't bang 2nd gear on light acceleration. Should be much more streetable.

Next step, get that Circle D in there!
 
Re: Project LQ4 - V8 S10 - Now with Circle D!

Well it finally happened. The Circle D is in!! It finished up pretty late so I didn't get to drive it much, but in a little amount of time I can tell a HUGE difference. The engine RPM's much quicker, and just starts to hit the sweet spot before the TC really bites. Bye bye back tires! I'm looking forward to putting some miles on it to get a better feel. Being a part time transmission guy, I'm also curious to see how it affects the trans temps.

I'm not ashamed to say I had someone else do the work. I have a friend who I trade favors with. I was up on him a couple. That plus a little bit of cash got it done. I would rather spend a week casually building a 60e than one day fighting an 80e out and back into an S10. Did it once, not again if I can help it.

Anyhow, it developed a slight case of NVH. I'm almost certain the exhaust is touching somewhere. It's so tight in there. No big deal. I'm just going to loosen all the clamps, tweak the pipes and tighten it all back up. The heavy work is done, and that's what I didn't want to do! Will report back after I put some miles on it.
 
Re: Project LQ4 - V8 S10 - Now with Circle D!

I had just enough time before dinner to address the exhaust. I put it up on jacks and crawled underneath. Couldn't see anything touching, but I went ahead and moved things around to where they were before, Apparently that worked because the vibration is gone. It's back to good!


I may have also ordered a cam for it. It was on sale. :th_winking:
