Badass setup! Hope you get the issues sorted out before your shootout!

Interesting to hear about the vehicle weight being higher than expected. You have quite a bit more stuff in it then streetthisevo, correct?

 

Dang thats sweet! Cant wait untill it finish!

 

Sweet, hope we see some solid improvements on the drag strip with the auto EVOs.

 

this is so awesome i use that same shifter in my 65 nova th350! Having a manual valvebody auto is INSANE when it comes to shifting. can't wait for results

 

Great writeup! Your story had me cracking up! I can totally see Dan saying that!

Are you able to compare RPM and vehicle speed to get an idea what the percentage of slippage you're seeing in the torque converter is in 3rd gear?

 

I haven't driven it enough to judge converter slippage, right now it's as loose as we can build it, the idea was to start it as loose as we could and tighten it up if need be. At cruise the slippage is going to low, there is very little power produced.

 

That is a pretty wild set-up. Makes sense for what your trying to accomplish. Good luck DB!

 

Can't wait to see what comes of this

 

very cool stuff few questions if i may.

the way you worded some of it says your using a different trans then the one ER is using. are the gears and ratio's of ER's trans and your trans the same??

also for a street car going from 5 speed ''stock'' FD to the auto 4 speed. if you have exactly the 2 same cars with same mods and exact same power and put the 4 speed in one and the 5 speed in the other which car will come out ahead from a role. i am guessing from a dead stop the auto would kill the 5 speed. but what about a role. from 40mph to whenever.

 

I have to admit, I'm really interested to see how this turns out. Sounds like a good option for people who love crazy power.

 

Well, remember this is not a fully auto. You actually have to shift it. The only thing is you shift without the clutch. My guess is that the car with this transmission will be faster since the turbo won't stop spooling with each shift.

 

your not taking into account it is an auto. auto's eat up more power then a manual. and i know it has to be shifted. i do not expect it to shift on its own. and even if it did the question i am asking is with the exact same car setup, power just one is this 4 speed auto and one is a 5 speed manual on a role starting at 40 to 50 mph ''being in each car's optimal gear to start the pull'' what car will be faster/quicker.

 

Even given the efficiency losses of an automatic over a manual trans, an auto will almost always be faster. The torque convertor can multiply torque, the shifts are faster, for a drag car, an auto will always be faster. If you're asking which will be faster from a roll, then I'd probably still bet on the auto, as you'll be able to brakeboost much harder with a torque convertor.

 

It will be interesting to see what broke Dave. I find it hard to believe that these transmissions are weaker than an early 90's DSM trans.

Your son might be right! You jumped in with an insane amount of power for a test bed....but hey I like your style! The install looks factory

I have to mention, and enough cant be said that 2 of the very best shops are working hard at this and its great to see that type of trust in a competitive market. Kudos to ER

Now if you ***** werent so tight lipped I would still have my Evo

 

From the start English set out to offer their set up for the masses to bolt into any turbo kit, I didn't want to step on their toes with that and told Aaron I'd take a different route with what we offered.

The roll racing it's hard to say. Typically the stock final drive will ET better in an EVO from what we've found VS a 4.11 gear. Now, if your car is out of power up top in the RPM and you have to drive the car in that range to finish the 1/4 mile then the 4.11 gear set will make the car faster because it keeps the RPM lower and the engine in the power curve better.

Another point, an automatic car will not MPH as high as an auto car BUT the ET from the auto will be better. So from point A to point B the car should be quicker but will not have the MPH of a 5 speed car. My best to date is 9.04 at 159.64 mph, I don't expect to see 159.64 mph again, I'm guessing at best my car may MPH around 155 now but I am hoping the ET's will be in the 8's though. I'd say that if you ran someone from a 40 roll that the auto would be quicker and get out on the 5 speed car initially. With the higher MPH though the 5 speed car may just reel it back in.

**Side note, the 5 speed car would reel it in until he missed a gear! hahaha
