LOL

Here is a 0-90 vid Wheel spin sucks. Had to feather the gas quite a bit.... and comparing this vid with the one below you can see the torque converter difference. I'm curious how much stronger it may pull with a lesser stall converter.


OH and here is an acceleration vid with my STOCK 3100 in my red beretta.




AND you cant forget the ole 100 shot on the 3400... This was as good as it was....



I think this car is much faster..... I just gotta make it stick...

yah the converter is really only gonna help u when u stall it out, there really isnt much more itll do besides help you on your lower end, but you have gearing for that anyway and not a huge cam, just a bit lopey. id go with a lesser stall like a 2500 or so and ull prob like it better

[3400-95-Modified]

My cam is pretty big... its 515 568 its not a small one...

Ben what do you think?

I was just saying you can see how the RPMs stay much higher after a shift with that converter. I could go with a 2500, but this is a Yank performance converter and I really don't feel like dropping the trans AGAIN...

I'll see how it runs at the strip first.

Yes, I'm a fan of low stall converters. I like to tap the gas and feel the car lunge like a manual does, not rev up really high and feel mushy. You'll get more HP out of a lower stall as well, better MPG too. What is the powerband of that cam? Hopefully not too high so that you can't cruise at a lower RPM. I did notice the other day in your other videos that 50-to-2nd downshift the RPMs were way up there. I'm guessing that's mainly your gearing.

[gectek]

i know ur cam isnt mild, but it wouldnt need that converter to keep from surging and messing with ur power band. the lower stall will feel like isaac said alot better in the lower rpms, idk if you have noticed but with stall converters, that number is like the magic number where the car acts like it should, it finally wakes up below that feels too mushy. i went with a higher stall on mine and it is fun and i can stall it higher for launches and what not but i just really dont like the drivability of it, but i think ill keep it and see if i like it after i do some more mojo on my trans and engine, to each their own tho

Well remember this is a toy car... Not a daily driver. Its not as mushy as my PDQ one that was in the red car for all of 30 min... this will move when you tap the gas but yes its not as snappy as a lower stall converter.

If I were driving this car day in and day out then yeah I would think about a slightly lower one. For right now I think I'm happy... A dyno sheet will also help me in that decision.

[gectek]

yah it will dyno higher with a lower stall, but they dyno sheet is just power to the ground, like u said u already have probs with that in keeping the tread on the tires. there is no way that a dyno can tell u raw acceleration, i know i run a mustang dyno and their 1/4mi setup and config is neat, but it isnt real. it cannot tell u what it will do because on all the dynos i have seen it will not allow you to flash the converter before you take off. power numbers are great and real but 1/4mi says so much more...very nice project and keep the numbers and vids comming

[3400-95-Modified]

Vid and numbers will be posted Sat of next week... June 7th hopefully... I'll keep you all updated.

Another thing is if I go lower in stall then I bring out the possibilities of breaking axles launching due to the torque.

[gectek]

well it isnt going to increase your torque exponentially, you will still have the axle loaded when u flash the converter, when u stall at a higher rpm and get more into the powerband of the cam, then u can break axles

[IsaacHayes]

Yeah I'd have to agree. Launching at a lower RPM is less stress than if you were to stall up to your power band and take off. Launching with a lower stall will affectively slow your initial jump off the line since you will be lower than your peak torque curve. Your best torque isn't going to be at 2000 it's going to be higher than that. You'll bog the engine more right off the line with a lower stall but if the engine is tuned well and running strong you won't feel that, you'll just save your tires from going up in smoke.

BTW, hows that trans mount feel? I noticed on the 1-2 shift since installing my CNC torque strut, the car no longer jumps/torque steers/lurches to the right, but now to the left... Whatever side has the mount that gives the most is where it will pull, and now that is the trans mount. It's almost as bad as when it was stock and the upper mount was shot... well not quite as bad it hasn't pulled me into the other lane ... yet.. LOL

I havent run it with the DR's on it yet and the LSD... I may not have wheel spin issues once those are warmed up... It's still an unknown.

[SappySE107]

Gas mileage should be the same as your converter will lock up at a lower RPM than your stall. The more torque you put to it, the higher it still stall. 3k is pretty high but I wouldn't pull it out without testing it completely. I couldn't tell you what optimal would be.

[SappySE107]

oh, and the stock vs now video is insane. Not even close:P

[3400-95-Modified]

Funny thing is I switch back and forth between the two cars on a weekly or daily basis depending on whats going on... Talk about feeling like a lump of chit... LOL At least the dialy has the nice stereo. Only thing is I wish my daily had cruise control too not just the toy.... OH well.

[IsaacHayes]

Yeah. That stock is pretty weak. Driving in town I don't notice my converter locking up, unless I am at highway speeds. So in town driving was what I was referring to more. At 55 or so it's at 1500 and in town at 30 it's 2000 or something like that.

Jon, I edited my post above (wifi acting up, didn't get it edited before you replied)
