Yea I hear ya!!

 

Here is a run I made at Mopar at the Rock. This is showing how it launched and spooled, it is a six speed so almost no boost. I even red lighted, the first time ever, I have always left on the last yellow, but it got me with a -0.028 reaction time. This is the 64/65/13ss, Smarty 4.11 and TST. I had the temp. limit set too low so it defueled before the end of the 1/4, so that is why it isn't a good pass. The black truck is a hopped up SRT10. Tac

Wow that didn't look bad at all lag wise!! You said you launched on no boost in that video? You running stock injectors? What settings do you run? Whats your EGT at 1/4?

 

jeff just buy that turbo and get it over with

 

That is stock injectors and cp3. With a manual, it is difficult to build any boost when coming of the line. I was reving the engine to about 2500 rpms That was Smarty 4.11 on level 9, TST on either 2 or 3, 0 torque, and rail pressure from TST about 5. End of the quarter egts were about 1450.

With stock turbo and towing my bass boat with Smarty on level 7, I would easily hit 1500deg before the end of the ramp getting on the interstate. Now with the 64/65/13ss, the same type run I can't even get 1400. So it cools well. Hope this helps.

 

Yep! And mine are twins! This truck rocks from a stop.

 

Are you running the 65 or 71, and a 74 or 80 on the bottom? What size fluxs are you running?

 

BLWNSMKE - Be cautious about advice from members with manual trannys (no offense guys).
The automatic is a totally different animal! Most members have not driven both to fully understand the differences.
TNLoneWolfe, post # 22........ and Spooler, post # 26, are right on.

In 2004 I went to a HX-40/HX-55 Hybrid (basically a 64/72/14) and hated the slow spoolup. With big injectors and a TST box I was a smoke machine below 20 mph unless I turned the box off. The newer turbos you are looking at are much better at spooling up than what we had to work with 3-4 yrs ago, but be warned........ too big is no fun to daily drive with an automatic tranny!

they are essentially one in the same, but I prefer how II sets up their wastegates vs. HTT. I think they crack open a little later yielding better spool up at a given max boost level

 

Thats exactly what I was looking out for.. Jeez this is a hard decision

 

I have ran the 65 and 71 wheel on a 62 with a manual trans.There is definitely a noticable lag going to the larger 71.Can't say I have much seat time in an auto but if they are slower to spool a turbo than the manuals I would stay away from the 71 for street use.
Took a ride in my friends truck the other day.He has the 62/65/13 and I could really tell the difference between his and mine.(both manuals)Much quicker to build boost.We haven't raced but I feel sure he would eat me up the 1st couple hunrdred feet!Now on top end, thats another story.

 

If it were me, I'd do the 64/65/13.... and live with a bit warmer top end.

Single turbos (all turbos actually) are a compromise. Remember you spend 99% of your driving time at less than WOT! And 3rd Gens handle the higher EGT's a lot better than 2nd Gens. JMO

We lead you to the water now DRINK..........LOL


71 wheel on a 62 is barable driving empty but somewhat smokey if you stab it from a stop. I had help setting my truck up with the TC and already have 4.10 gears with stock tires. I do pull heavy and it does get hot starting out but once going it is O.K. I would go with a 65 wheel if I were you. I bought my turbo new/used so to speak knowing I may not like it but with HTT that can be fixed. So far, I can deal with it. I haven't pulled with it yet with the Smarty. We will see how I like it after that. The Smarty fuels more down low that is for sure, hence the smoke. We shall see.

 

I daily drive with a 64/71/14 on my 2nd Gen and love it. I have a pretty tight TC to boot. I think it spools better than my old 64/65/12! Major reduction in EGT when racing.

 

if you decide you want to go to a 65mm turbine, I should be able to accomodate. I'm getting an HTB2 rebuilt as we speak
