Engine/Transmission (1998.5 - 2002) So, who has HTT's new Super Stock 62/13SS

[Todd F]

I am looking for some feedback on HTT's Super Stock 62/13SS (stainless steel). A new turbo will be purchased soon and I think this is the one I will be going to get. Hopefully there are a few members that have put some miles on this charger

BUMP... .



I am looking for same feedback, except I am settling on 64/13SS.

I was hoping there would be a few members would have this turbo by now. I can only buy a turbo once and want too make sure the Super Stock 62/13SS is the right choice

 

[Todd F]

Lets try this one more time. Hopefully somebody will have some input on this turbo

 

[LOtero]

im with you man, sorry we havent heard anything back...

 

[EBung]

I am inline also. I am going to call them again monday.

 

[Todd F]

I am might to wait awhile for more feedback on the stainless exhaust. There is a post on another board about spooling issues on the 64/71/13SS by a few members. Hopefully they will figure out their problems as I really do not want to purchase a laggy turbo and was hoping the SS was the cure

I am running a 64/16ss as a secondary charger. It has more lag than a 62, but not bad. I ran it in a . 8 housing for a while and liked it alot. 13cm is suppossed to be here any day.

 

[tlgdiesel]

It is total garbage the 13cm ss housing sucks. My dad ran it on his 04 which is putting 700hp to the wheels and it didnt spool worth a darn. If a 24 valver wont spool it a 12 valve really wont. I havn't been able to run it on my 12 valve yet do to being in the middle of an auto transmission conversion. My 14cm cast iron housing is on its way back to me. That was a 64 71 13cm ss.

Just great... ... , I might be glad I didn't pull the trigger last week and buy this turbo. I still would like to hear from a few other 2nd Gen. owners that are running the 62/71/13SS. None of the 3rd Gen trucks are seeming to have any luck with this charger



Maybe I should just buy the SPS 62/14 instead...

 

[AFoulk]

I've heard from a couple guys on hear that run the II Silver 62 and love it. Maybe thats one you wanna take a look at too.

 

[Todd F]

Ya, I am very disappointed with the findings of the 62/71/13SS from HTT. Every day there seems to be more and more people that are very unhappy with the performance of HTTs lastest and greatest. I really thought this was the charger for me... . :{



The Silver from II would be alittle overkill for me but the Super Phat Shaft 62/14 should fit my needs very well. Now I guess I will need to work on some pricing

 

[RonA]

Odd that people are complaining. I don't think the 64/16ss is laggy. I don't see how the 13 could be. Especially with a 62mm compressor. I guess it must just be the difference between trucks and fueling.

The Silver62 is a great street turbo, starts to spool about 1400 rpm on my truck, and is wicked fast from there. It is however, very disappointing for towing. You cannot cruise in OD, light throttle and maintain any boost, egt's 1400+ on the slightest incline. If you downshift, and keep your foot in it, 2500+rpm, sure, it will bring the temps down but I do not like driving that way while towing my 5vr.



The SPS62, with the 71mm turbine performed as well on the street (truck only), and really shined while towing. 55/60 mph in OD (3. 73s) light throttle, I was constantly at 12/15# boost and would just climb from there. Fueling mods the same, I never got above 1300f egt's.



Sorry about hijacking the HTT thread, but I thought you might like to know my experience. Wish I had the SPS62 back, I wonder if its as simple as replacing the 74mm turbine wheel with the 71mm wheel? Probably not, the housing was most likely machined to fit the larger wheel. Jess

I've had my HTT Super Stock 62 on for two weeks now and I don't have any complaints. My turbo make 38 lbs of boost with my F1 1. 6 90 HP injectors. I have seen a significant decrease in smoke with my Smarty on level 8 stacked with my Comp on 6 x 6 compared to what I saw with my S300 turbo. My EGT's still run in the 900 - 1050 F range while towing (Smarty on 9 solo). Spool up seems to happen at a low rpm. I think my SS62 spools better than my S300.

You can hear a noticeable increase in turbo whine at low RPM compared to the S300. When you back off the throttle with the turbo spooled up you can hear the turbo spool down loud and clear. Smoke in the 30 lbs of boost range and up is noticeable reduced compared to the S300.

While cruising on the highway (no load) in 6th gear I start to make boost at about 75 mph. This allows for great passing power. Mash the pedal to the floor at 75 mph and you jump to 90 mph in a few seconds. Passing power starts to become useful in 4th & 5th gear. I'm sure if I had an automatic the acceleration would be very impressive off the line. With the six speed it's time to shift gears every few seconds in gears 1-3. You have to get into 4th, 5th, & 6th gears before you can stay on the boost long enough to start to really going like a bat out of hell.

I'm making 447. 5 horsepower & 983. 5 lbs of torque with my current setup. The most important thing is that my setup runs EGT's that many people would kill for. I can pull 16K - 17K with my Smarty on level 9 and barely have my EGT's hit 1000 F cruising up hill.

My 13cm ss housing came in today. It will be interesting to see the difference between it and the 16cm.

Keep me posted on the 13cm. I want to hear from somebody that is impressed with the turbo..... So far all I am reading mainly is from upset customers that can not get any decent boost numbers out of it. There are one or two people that say the stainless exhaust is OK at best.

 

[RonA]

Don't forget that an army of happy customers doesn't make nearly as much noise as 1 unhappy one. I really like my 64/16ss. I am quite confident the 13 will spool quickly. My only concern is how it will do on top end. The . 8 cast iron was really good on top, excellent on the bottom and midrange. The 16ss is a bit lethargic on the bottom, good midrange, excellent top end. If the 13 chokes on top I will have HTT make me up a . 8 cast iron with the twins wastegate mod.

If you read between the lines, the ones that are having problems have purchased the wrong size turbo for their application. In most cases too big of a turbo. You need to establish your base line of boost ratio to drive pressure ratios before "just" buying something... . The HTTss turbo's have much larger wastgates, therefore when they open, "they open" which is a good thing, however, it takes a lot of more HP to over drive the turbo to increase boost which everyone thinks gives you more power. In fact if your drive pressure is higher then your boost pressure, you are loosing available engine HP and causing excessive heat (EGT"s). Everyone thinks, they need 45 + lbs. of boost, which in reality if they didn't know their drive pressures, 35-38 lbs. would be sufficient and they would gain more HP. A turbo is only one componet for a properly tunned engine, along with performance goals, use ie, towing, racing, sled pulling, fueling boxes, injectors, lift pumps, intake, exhaust, altitude etc. , all play an important role in determining turbo size.



Bottom line, don't read to much into people having "bad" experiencies with turbos etc. , in most cases, the person having the problem is not providing "us" the reader all the facts and/or truck information to validate if there is truely an issue.

Seems most are commenting on a 64SS13 not a 62SS13. Going from a 14 to a 13 exhaust housing but keeping the 71mm exhaust wheel shouldn't produce drastically different results.
I've not run the 62SS13 yet, but have run the SPS62, and HTB2/14, and am looking forward to trying the SS13 very soon.

The individuals I have talked to that have run the 62SS13, do like it.
