pt-52 vs. pt-61

[john evans]

what is the difference in size and performance between the pt52 and pt61.i have a 3000 stall 9" convertor now.thanks

They are almost identical in performance,and for size the wheel inducer/exducer is just a tad bigger on the 61.It appears the 60 series are the new fad,and 50 series are "old school".So if you plan on trading up in turbo series in the future get a 61.That way you will have some resell value.If you are looking to upgrade cheaper buy an old junky used 52 and go just as fast.

The 60 series turbos were out way before the 50 series.. The 60 are 'older school' then the 50's

actually there's a pretty sizable difference between the PT52 and the PT61...the 61 will support nearly 650 net horsepower while the 52 supports about 600

the 61 is different then any of the "old" 60 series turbos or any of the 50 series turbos as it uses the new Garrett GT compressor wheel which is off the GT35R ball bearing turbo...this compressor wheel is MUCH more efficient than any of those other compressor wheels...meaning it doesn't heat up the intake charge nearly as much as the other turbos do at high boost

not to mention this is a quick spooling turbo that requires a 3200 stall and even a 3000 stall would be livable...

unless you are looking for a mild stock appearing turbo...this 61 is the ticket...

LOL...I hear ya Frank but the 60's are the new rage,gotta haves,and the 50's are the old junk.Look at Don's sales pitch for verification.All the new technology and yada yada yada,and it makes a whole 50hp more with a bigger better turbo?Not so different to me.Especially since I have been just as fast with my 52 as Don has with his 61.You could also list a 52 for sale,list a 61,and see which one sells first.Bet the "rage" will be gone asap and the antique outdated behind the times 52 will be getting bumped like a mother.Then again that might be the 50's rap as a time bomb waiting to happen.Me personally have had nothing but success with the 52 and think it's a great street turbo.Lots of miles,lots of abuse,and would never even think of getting rid of it to supposedly "upgrade" to a 61.

I am not knocking the 61 being a good turbo.I am sure it is.I just don't agree with the sentiment that the Q-Tip was just invented, and everyone else is just digging in their ears with their finger.

hold on a second here...

I never said if you had a 52 turbo that you needed to upgrade to a 61...why would you want to do that??? I'm saying this turbo is the upgrade over such turbos as a 44 or 49 or a stocker...if you already have a 50 series turbo then you are fine...there's no need to upgrade to a 61 in that case...hell if you were to upgrade from those turbos then you would go to a 67 or a 70...let's all get on the right page here...if I sounded like I was bashing the 50 series turbos then I apologize but I was not...

I'm not in competition with anyone on this board and I don't really appreciate this comment...and besides my car wasn't even tuned and I had a lot of things working against me when I was at the track this fall...hell I had only had the car out for a whooping 2 months with this new combo when I ran this time and it was my 2nd trip to the track all season...I do believe my car will be a consistant 11.00-11.20 car once I get all the tweaking done...

Didn't see what times you ran on the 52??

The only time you switch to a 61 from a 52 is when the 52's exhaust wheel is all chewed up for whatever reason like mine was. I then went to a PT61 ptrim, and there is a day and night difference between the 2. The 61 pulls harder at 17psi than the 52 did at 25psi.

Only went to the track a couple of times Donnie.It's a daily driver.The first time I had just bought the car and it had some issues with tune and what not.Only managed some low 12's.Talked to some gurus,got a Testa chip,and went back.Made 3 11 sec passes between 114-116.Best it went was 11.88 at 116.20 with a 1.83 60'.All passes were on BFG's just like you .Drove it there and drove it home which is no big deal,but the track is a 90 mile jaunt each way.My worst pass was an 11.98 at 114.72.I really sucked driving the car.Anyways no excuses for the times as I think that is what the car should run at the least with a 52 for mph.

I made those runs with 100k on the clock with the motor never touched.Never opened for a thing.Stock mount cooler,downpipe,exhaust,mass air/translator,hot wired pump,plug wires,and tranny/converter.

Which bring me back to the question that was asked:

what is the difference in size and performance between the pt52 and pt61?

and my answer is still very little.Since you and Don seem to agree that a 61 is not worth "upgrading to"(until it grenades) I would say we agree?


Don sorry if you took offense to that statement and I am not in competition with anyone either.Your car,your times,and when/how often you had been to the track are just very very similar.I made the statement for comparison purposes,and not competition purposes.

I will very soon let everyone know how fast a 52 is with ported irons,cam,and a rebuild.I am kinda of curious since I have a baseline with a completely stock motor.I will still suck driving though,and have contemplated slicks to help with launching.Don't know if that matters though as far as mph is concerned?

Anyways enough of the ramble,and hopefully I won't need a 61 after my next track visit due to flying exhaust wheel pieces.Quit trying to scare me Donnie.

Just FYI,

my car went 11.38 @ 117 with a bone stock longblock on the 52 turbo. I then went 11.14 @ 118+ with the built motor aqnd the 52. I ran out of fuel on the MSD 50's I was running and didn't want to push it any further. I have no doubt it would have gone further if I had the fuel to support it.

FWIW, as far as I know, the PT61 is just a TE62 with a "GT61" compressor wheel. So it should be somewhat of an upgrade, but I wouldn't do it unless you had the convertor to support it and it didn't cost you mutch.

 

[d0n_3d]

guys...the PT61 uses the SAME T-350 exhaust wheel as the PT52...the only difference is the larger GT 61mm compressor wheel. It's worth 30-50 horse depending on compressor cover but again like I said earlier not a drastic difference in power. If you want to upgrade the 52 then go with a 67 P-trim or GTQ depending on heads and cam setup. Plenty of guys on this board can tell you all about how fast they are going on the 67s...

Don,

What does it cost to upgrade (rebuild) from a perfectly good 52 to a 61???

Thanks.
