Well can it be done?

My goals have changed since I did most of my research on turbos. My truck is now used for fun 90% of my miles 5% are loaded with less than a 1k in the bed and 5% of them are towing 7-8k 5-6 trips a year. I am willing to run in fifth at 2250rpms to help keep things cool while towing, but I don't want to build a truck that is useless for towing. I understand that it will take some paying attention, but I don't want to be scared to tow with it. I have heard both sides of the story from the people who manufacture the turbo and just want to here some real world opinions. My goals are to hit 500hp with what I have now and maybe just crack 600hp when I have an SO pump on there and a good set of o-rings and larger injectors if need be to get a few more ponies. I love racing my friends on the highway on both flat ground and on grades. 50-110mph were common place until I installed the injectors and now that is out of the question as far as I am concerned. My guage will hit 1500* just rolling into it hard and I miss being able to plant it to the floor. My ultimate goal is to make the truck as usable as possible while not exceeding 1500-1550* at any given time. (priority number one is not cook the engine)
So I know its a fine line of big horsepower and functionality but I want to know what you think about running this turbo.
What can I expect?
What do you think?
What do you reccomend?
What do you reccomend if this is totaly out of the question?
Basicaly I want to know your thoughts good bad positive negative.

I just want to elaborate on the fact that I know this is a fine line. I can't do twins its not in the budget. And I know that a great HP truck isn't the best towing truck. I want to know what you think mainly because there is no one in my area that is running a large single so I can't go for a ride with or without towing a trailer. And the techs at HTT have me confused one was making me shy away from it while the other made me believe that It could be done. Said it would just take a little paying attention while towing, would run warm while empty, and that it would have a decent amount of lag but when it hits hold on with both hands and don't even worry about egts with the amount of fueling that I have. Said that if I hit 1500+ it would only be at the very end of a WOT run for just the last couple seconds if that and by the time I did that I would be letting off the throttle.

So thanks for your time thoughts and opinions. If this gets shot down the drain I will be looking at something a little smaller based on reccomendations.
Thanks, Chris

 

Even thow I have a CR I still have a 66 Charger. It's not fun towing but is quite doable. surging can get pretty bad at higher boost levels and things can get toasty. They are not towing turbos. I have towed over 10k with mine and it surges and smokes pretty bad when I hit any type of grade.

 

IMO you are going to be better off and happier with a 64/71/13. Cost should be close to the same. It should support the HP you're looking for and will be better for towing. If you're only going to be around 500 RWHP for a while you are going to hate that turbo, and can forget about towing.

 

I agree with it getting alittle warm and surging.

Call HTT, they will tell you what will happen. I talked to them on the phone for about 30 minutes, and they knew their stuff!

 

The 66 on a VP truck will surge while towing.... Also egt's will get very hot fast! This turbo is designed for performance under WOT conditions. The 62mm you currently have will yeild 500-525 RWHP without a problem. Towing and driveability will be much better than a 64 or 66 turbo.

Pretty much on a VP truck a 62mm is good for 500-525, 64mm is good for around 550-575, and the 66 will get you 600+. With turbo's everything is a compromise, bigger can yeild greater HP but lowend and driveabilty suffers. Most guys I have seen go too large thinking they will grow into the turbo. I would recommend realistically looking at what you want from your truck and choosing the turbo for the job. While towing with the 66 can be done it is normally not pretty.

I have tried towing with a 64, not fun at all. EGTs were average of 300* higher than with my 62. I thought we had you figured out & now you walk into the baseball game & try playing hockey. LOL

 

You will hate the 66. My brother has one on his VP truck(sledpuller) and it takes FOREVER to build any boost. It will make over 600 on the dyno but it's no fun to drive on the street and though he has towed with it, it's not recommended... driving by the pyrometer even with things 'turned down'.

 

I have a HTT 64/14 on my truck. Put down 416hp/892tq on Saturday.

Used to have a PDR HX40, but couldn't control the smoke. EGTs towing, I couldn't keep out of the red unless it was under 40*F, and that was with a small enclosed trailer.

I've grossed ~28k with the 64, and had ZERO problems towing. EGTs didn't go over 1150*. The lag is the same as, or slightly less than the 40. Since you have 3.55 gears, I'd go with a 12 or SS 13 housing to reduce lag.

The only lag problem I have is if I can't force a downshift stomping on the go pedal. Then it is total blackout til it lights. Planning to do a 3 position TCC switch to force unlock in those conditions. From a standstill and romping on it, it flat takes off if I drop to first and hit it. If not, lag and smoke city.

With everything, it has a learning curve, and it works very well as a daily driver and tow rig for me. A set of twins might be better, but I don't have the funds for them either.

 

Well I figured that the consensus would be negative, but It is a killer deal price wise. Its a used one. Just got in in my head. It was cheap and you know how you get these ideas for a week or two thinking oh I want to go big and bad. Then you come back your senses. Realizing that what is realistic is alot different than what you were thinking. The cheap price and the fact that I just went to a J&H performance event got me thinking. Even though I knew it most likely wasn't a good Idea. Now if I go buy a new one what do you guys think. I have been thinking. HMMM I have talked to several people and they have reccomended experimenting with a 62/71/16ss reason being that it would tow ok for the little amount I tow. Would have reasonable spool up times and that the larger exhaust housing would help keep me cool when I am racing up a grade or going flat out from 50-110+. That is were I like to have fun and I don't want to be risking melting anything down. I would like to be able to use all the fueling that I have and not go to much past 1500* on WOT run. I have been told that the larger 1" ports would help and that this turbo could be used in twins if I go that way and it would eleminate an external wastegate. Makes good logical sense to a very uneducated man in the turbo department what do you think? Seems like the 62/71 is a great all around turbo. You can tow, keep egts manageable and still put down 500+hp. But how hot will this thing run in the above scenarios. I haven't seen to many people run the 16ss so if I run it I guess i'll be the test pilot. Still open to any reccomendations. Thanks for the help guys. I thought I knew what I was going to get but maybe this 16ss could help my top end alot.

 

There's a reason you see good deals on 66 chargers. Most of the guys who buy them are sorry they did, and are selling the charger at a major loss to try and get some usefulness back out of their truck.

I couldn't be happier with the SPS62 that Jetpilot recommended for me a year and a half ago. It stays cool towing and around town builds boost around 1500 rpms and takes off around 1800-1900. Cruising temps at 70 are about 8oo with about 3-4 lbs of boost unloaded and loaded are only a few hundered degrees higher. I am at sea level however. Just towed a Jeep to Ohio last week and cuised 60 -70 and got 16.5 mpg with the adrenaline on pl03. I've not been on a dyno but would think I'm near 475-500 hp and on a wide open run temps aren't over 1550. I love this turbo! Thanks Doug.....................Brad

 

BSP what size housing do you have?
HOHN I kind of figured that, you hardly ever see a SPS62 in the classifieds. Once in a while you see one and the reason usually is that the guy or gal is going for big power. I do want a useable truck that is why I have a truck, allthough I don't tow often that is why I have one and I can't afford a truck for towing and then have a hotrod to. I am just trying to have both with the truck. Mostly for fun but still need to get the TT there and then I can have fun with the truck.
Another note on the SPS62 is that I have seen posts were people went bigger and were sorry they did, and wish they didn't make the swap.
Well I am pretty sure that it is going to be a sps62 just like I have been thinking it will be for the last 6 months. But I am now going to be researching on the exhaust side of things. Not a 12 for sure but, there are the 13ss, 14, and 16ss to read up on. Anybody got any experiences with any of these that you could share with me primarily the 13ss and 16ss.

 

It is a 62/71/14. Lots of folks are happy with the HTT 62/13 as well.......Brad

 

As mentioned above, go with the 14 housing or the 13SS. The 12 is too small to take advantage of the 71mm turbine wheel and the 16SS is a PIG.

Jetpilot which of the two housings would cool the best? (WOT) I know the 14 is physically larger but the 13ss has been said to run cooler because of materials used. And would the fact that it has 1" ports help in any way to keep things cool?
