Engine/Transmission (1994 - 1998) Best turbo with #10 plate?

[JGrover]

Dummping my Banks plate for a #10 plate next week.

I really hate turbo lag. In 8th/double overdrive with the gear venders im 1500rpm at 65mph/1800rpm at 80mph. My towing is done in 4hi@1900rpm 65mph. Saving that 5th gear

Truck pulls long big hills with a 9k boat 17k fully loaded GVWR. Im going to run the #10 plate in the stock position. Im guessing my 14cm quickspool is going to get toasty.

Looking at the Auroura 2000, Hybrid 60/14, or a HTBG

So what do you truck experts think?

I need to do research on the Valet switch.

Is that for a 12V?

Does that cut the fuel flow for towing?

 

[bmoeller]

I think a HTT 62/12 or 62/14 would be fine. Has dual wastegates. Lag should be minimal. They light pretty easy.



The valet switch on a 12v limits how much boost the AFC housing will get. With it getting less boost, it will allow for lower amounts of fuel, which cuts the power.

 

[zstroken]

I think the 62/12 won't work for you. I had one on my 24V with 130 hp injectors and the edge box on power level 1. In 6th gear I had to be above 2000 rpm towing 12K to keep the egts cool. They would hit 1300, once I got past the 2000 rpm it was off to the races and it would stay cool until I got my foot out of it.

Your just too low of RPM. I would think that a hybrid 35 might be a good bet.

 

[San Felipe Bob]

I love my combo

I have my 10 plate full forward for max power.

It gets a little hot when towing.

I have to watch the EGT gauge closely when climbing hills.

Flat ground is A-ok.

I have the 35 Hybird with a 14cm wastegated housing.

I also have the valet.

I only use the valet when other people drive my truck. (Wife ect. )

I have the 3k gov spring's

I have the star wheel adjusted to minimze smoke and slow the boost down just a little.

This helps take some strain off the drivetrain.

If I back off on the star wheel it spools very fast and will smoke the 35" tires and thats with 3:54 gears..... ( oh yeah thats not counting the Black smoke)



Like I said I love my combo...

High Tech 62/12 or possibly a 62/14 would certainly handle your demands and provide room to grow.

Yes, it's for a 12V. It prevents the plate from being in the picture. The rack won't travel when it's on.



Yes, it cuts the fuel for towing. Depending on the size of your injectors, the size of your towable & if you have any hills, you might or might not tow with the Valet switch on.



I had a Valet switch. It only gets you better mileage if you can't drive "easily". It's not being used as a Valet switch now. It's been "reassigned" duty as part of the Hobbs Switched Wastegate.

 

[How'dHeDoThat]

if you want to run that low of rpm and tow i think a hy9 would be your best bet. all the others are not going to have boost at 1600 rpm towing.

 

[zstroken]

Like I said before and How'd said the HTB2's will not make the boost you want at 1500. I towed with an HTB2 62/12 and it did a good job, but 6th gear below 2000 and it just would not cool. Saw about 1300 until I got over 2000.

 

[JGrover]

Looks like the HTB2 62/12 almost works. Truck pulls best@1800/2000rpm

Big hills, 5mi grades, 17k, 4hi 65mph@2000 1200egts,180 eng temps, (Saving my 5th gear nut) 4th gear 62mph@2200rpm 1050 egts, 200 engine temps. Thats with the banks stuff. #10 goes in this AM. See what happens.

 

[JGrover]

Installed my #10 plate today.

Plate. 20 forward. AFC cover full forward.

WOW! this truck really moves now. Oo.

Backed way off on the smoke wheel. Pulls down at 1300rpm, And at 1/4 throttle boost hits 32psi and at 1/2 throttle boost hits 42psi Thought them boost elbows are were set at 36psi.

What a blast to drive. What a great website to find the goodstuff to setup a 12V Hmmmm... . Do I need injectors : :-laf

Looks like a HTBG may be the turbo to go with. rated at 350/425 Hp and can upgrade to the HTB2 later if needed. they are rated at 450 hp min

I hear the oil return line is a real pain with the HTB's

I know with the#10 plate I will have more than enough power.

But if I want to go with injectors too. Maybe some DD3's(just for fun) I probably will get to hot for towing.

So maybe with a valet. Cuts the fuel for egt problems pulling the big hills.

I have a #10 in my 913 pump, 5-speed as well.

The stock clutch wont hold it for starters. I have a 13" luk cera.

Im also running a HX35/40 hybrid. It has a 14cm wg housing, and a banks big head WG actuator. I love it. It really woke the truck up, sounds cool, and lowered my egts pretty decent. I have it wastegated at 39-40psi now.



While towing, it seems to keep the truck cooler than the 35 did even at partial throttle. It spools just as fast as my 35 did.



I tow around 5,000' altitude always, and with the 10 plate i have no prob. Even with the 0 plate there is no prob. I have the starwheel loose, afc foward, and plate full foward.



At the strip on sunday, with the 10 full foward, It hit 1500* right as I went through the traps. Before with the 35/12 it would hit 1500* around the 1,000' mark. With the 35/16 it wasnt any better.



Im not sure it lowered my peak EGT any because I can still hit over 1500* if I want, but it gave me much more of a cushion while towing and playing around.

Its a great towing turbo... .

[RHARVEY]

Here is what I have used a number of times on customers trucks and works very well.

PDR HX35/12 housing ... also used a 14 housing a few times

#10 plate approx 45k back from stock ... to save stock clutch

3k springs

This combination has worked our real well... .

Your just too low of RPM. I would think that a hybrid 35 might be a good bet.

I take it you must be towing pretty heavy to have an issue like this. Does your boost fall off below 2000? What does boost run at say 1700 and 2100?



I have an older DD Jammer with 16cm WG housing on my '96 and I don't have to keep the RPM up to keep it from cooking. There's been quite a few times I've lugged it to 1700 going uphill with about 6000 lbs in tow. Pyro stays around 900 preturbo, might get up to 1000 if I push it. This is around 20psi boost. My turbo lights right at 1300 I think if I wanted to lug it at 1500 I could and not get it too hot. I'm not running a lot of fuel though, DDP stage II injectors and #10 2/3 forward (I have a 175 pump on my 5-speed).



No matter what turbo anyone runs though I think the engine shouldn't be run hard below 1700 RPM anyway, since that's getting into "lugging" territory and the engine is below its torque peak (where it works the best).



I really like the Jammer, for a HX40 16cm housing it spools real well and it's a sweet towing turbo.

I talk to Piers. There hybrid is a 58cm/14 Rated at 350hp

They told me a 60cm/14 hybrid would surge if pulling heavy. (which hi tech carrys) Rated at 400hp

I pull a 9k boat up some very steep long grades

Plate is forward . 020

Clutch is a SBC OFC 13. 25

My Sig only shows on my org post

The 12cm housing is what may be getting you hot. And a 14cm may have a slower spoolup but cool the towing egts down.

I dont know the diff between a 12v #10 plated truck and a 130hp injected 24V computer trk. What should your RWHP be with your setup? injectors/stage 1

What rpm does your 62/12 start spooling?

I believe he is pulling a 12k trl. Not 12k gvwr Im pulling only 9k uphill Soooo Hmmmm... .

I tow real heavy sometimes (18,000lbs) and have never ever had my 60/14 surge. not once. Even lugging it empty, or towing the boat/camper together. I cannot get it to surge ever.

In fact, if I would let the rpm drop to under 1,000rpm with the stock turbo (empty, of course) and then try to accelerate it would surge. I cant even do that with my 60/14. I do have the better 6 blade comp wheel, maybe thats part of it... .

yet I also have the big head wg actuator, which should make surge worse, but still no prob.



Since you already have a 14cm housing, you might as well try a hybrid of some sort. If you dont like it, you probably wont loose money on it since the 14cm's are pretty pricey.

[moparguy]

On surging. You can see what I've got in my sig. I have zero surge issues when towing 10k plus below 3500'. However, when in the Rockies, rpm has to be above 2200 or huge surge issues.



I'm running a HTT2 compressor on my 200k mile HX35. Surge is less since I've ported and drilled 1. 125 hole in the divider on the exhaust housing and installed a 1. 25 valve in the wastegate. And, adjusted the waste gate to limit max boost to 32lbs. Much better than the nowwasted 16 housing I was running.



I guess my main point is, one setup may not surge at low elvatuations, but at 7k and above have major issues.
