TA-61 Or Keep My TE-44 Turbo???

[Godzilla]

I know that the TA 61 is a very popular street,strip Turbo.I was wondeing would I feel the difference in power if I kept both Turbo's at 18 lbs of Boost on the street.I know I would have to upgrade my converter if I went with a TA-61.Thanks for any Reply's.

Imo you will see nothing for a power gain and require a looser converter. I run a TE61 on my blue car at 27psi with a 9.5" PTC. It has enough power to push it to mid 10's.

Yeah I want something on the street that makes my car feel and go faster.The 3:73 Gears did help but now Im back to the 28 inch tall BFG Drag radials.I know its not 27 PSI on 93 pump gas.I guess its either Alky or NOS.I have heard nothing good on nitous Turbo car's,even a little 50 shot of the laughing gas seems to destuct the motor.I am getting a new converter because the stock one sucks.

It is 93/alky. I wouldnt experiment with nitrous on 93 octane. If the octane is there its as good or better as it is on any other engine. I always start out with higher fuel jets than the rec and go backward because of the extreme cooling effect of the N2O. I run a 50 shot on my black car just for spooling and its off at about 20psi. Its triggered on and off by the XFI. Its a lot of fun. I dont agree that 3.73 gears are doing much. As you start turning the boost up they will likely hurt you.

Im sure its lots of fun.I did a 150 shot in a 69 BB Chevy in 3rd and 4th Gear.I couldn't believe what that felt like.Glad I didn't put the 300 Horse Power jets in.Everything was a blur.Well Im running on 28 inch tall tire's now so its closer to a 3.52 or somewhere in the neighborhood.I still would like to put back my original 3:42's.My Boost is stuck on 18 lbs of Boost.I have a inside controller but it doesn't work anymore.Its really only street driven so there's no need to turn up the Boost past 18 unless I go with an Alky kit.Top end power is not to good with those 3:73's.

You Think if I switch back to 3:42's and stay with the 28 inch tall tire,I would be more in the Boost range better Also I want to get a PTC converter would a 2800-3000 be about right with the change of Gear ratio??

I dont know what your exact goals are but if you wanted to have 10 sec potential id look into 3.23 gears and a PTC 9.5". PTC 9.5" are not spec'd by stall speed. You really need to keep the rpm between 4600 and 5300 with the stock cam and it will be hard to do that while turning up the boost unless the converter couples really well. If you want to have a mid 11sec combo a 10" PTC 2800 will do well. If you have a 6176 you might need a 3000. With about 5% slip you can trap 123mph with 3.42 @5300rpm. With 3.23's you can get it done around 5% at 5000 rpm. 3.73's will need 5800 rpm to get to 123 @ 5% slip. Even at 3% you are still at about 5700rpm. I doubt you will get there with 3.73 since you will need to get more spring on the cam than what most would think is necessary. Comp 980 or LT1 springs probably wont cut it with the boost and rpm you will be hitting with 3.73's trying to make a full pass for 10 sec potential runs. The less numerical gear you have the more you are working the converter. The higher you have the sooner it will couple but usually you will run out of usable rpm before you hit the traps. This is why the converter is so important when trying to squeeze e.t. out of small cammed turbocharged engines. My 9.5% PTC slips about 3%@132mph in the current combo. I have 3.42 gears and 27.3" measured tires (MT 275/60-15).

I thought maybe my car would be a mid 11 car with the restalled D5 the way it is now.I am going with a different converter.Alot of guy's are running 3200 converter's with the 44 Turbo.I wonder why??

They are likely not 3200's I had someone claim 3600 on a converter a couple weeks ago and it was about 2600. Mine is about 3100@ zero boost/vacuum. A 9" or 10" 2800 will spool a 44 very fast

Its hard to choose between a 9 or 10 2800 but it makes sense one or the other will do the job.The only thing is I don't know anybody that makes a 9 other then Art Carr.I know PTC makes a 9.5 2800 L/U converter.That would probably be the one I would choose because it seems to be the most popular.I was dead set on a Vigilante 9.5 converter for years now Im leaning to some others.

I disagree with the idea that a stock cammed car is out of wind by 5300.My car with a Ta61,Precision 9.5" n/l,3.42 ratio & bfg 275/60-r15's shifts 1-2 at 5600,2-3 at 5500 and pulls through the traps at 5500 without nosing over.Ported heads (which are in your sig) and proper exhaust work will synergize with the stock cam.

Ideally it wants to be under 5300. If you look at your peak torque its likely around 4600. What mph are you getting with the 61? Im about to run my slower car with a 61 and home ported heads with stock valves and PTC 9.5" with a 212/212.

PTC doesnt make a 9.5" LU. Only NL and thats the way you should go if you are looking for e.t. Dont go with an AC. Flash stall will be too high fo rthe small stock cam. The PTC 10" LU will have a hard time coupling if you want 10 sec power with the stock cam.
