I did my findings on the PTE6262 and FP35variants , there are alot of reviews and comparison of the two turbo FPnPTE. I was actually heading towards a garrett GT35R , but I would just like to know take a second and make a final choice vs the original GT

my question would be , why would you go for the PTE6262 instead of the pure GT35R ?
- does the PTE or FP spool faster
- does the PTE ceramic ball bearing last longer than the garretts
- the PTE has a smaller turbine wheel than the GT35 but does it flow higher
- will the extra dollars is it worthwhile


thanks a million

 

For starters, both the PTE6262 and HTA3582R are viewed as functionally superior to a standard GT35R in terms of sheer power potential due to the fact that both employ newer technology billet compressor wheels.

As per my recollection, I think it was AWDMike that determined that FP's HTA3582 is capable of both outspooling and outpowering the PTE6262 by a slight margin, but I have no further information. As far as outright power potential, this probably wouldn't make much difference for anything under 700whp.

I don't know how PTE's current CHRA fares in long term durability, and I'm not sure anyone knows the answer to that question. Garrett's DBB CHRA is of course, well documented.

As for if the extra cost is worth it, well, given that either is capable of delivering roughly a 10% increase in torque across the board as compared to a regular GT35R, I think you'll find that to be quite a bargain in the big picture.

 

Sorry but i have never with my own eyes seen a HTA35R which is the HTA version of the standard 35R make more power then a 6262 on the same setup The HTA35R when it was released was even told that it just out spools the regular 35R. Now of course people getting deals and making $ off one turbo company will say anything to sell what there making there $ off of so i don't even take there words into account.... Whether it be PTE, FP, BW etc "not talking about anyone or company in particular so don't jump to conclusions" I see things with my own eyes before i make a decision or believe ANY hype!! I don't read things i DO things And honestly there is A LOT of hype out there and misleading information these days! Personally i have seen about 150-200RPM spool difference IF THAT from a regular 35r to the HTA on same car with not much more power out the top end to speak of honestly.... The HTA 35R is a great turbo though i wont deny that and i actually like it very much for its intended purpose!! I have had MANY FP turbos in my day and been satisfied with everyone of them.

The PTE6262 and the HTA3586 would be a much better comparison.

 

Yep, my goof. That blurb should have been HTA3586 slightly edges PTE6262 by a slim (probably negligible) margin.

The HTA3582 outspools all of them, but probably shouldn't be considered IF the power target is >700whp.

FYI

 

Ted, it also looks as if the new FP HTA35xx will outspool the BB6262 and make more power. Mike made over 900hp with it. I do not know what size compressor they are using but I do know it is mix between the 40r type compressor wheel and the 35r turbine wheel. I would like to bet it is a custom 92mm compressor, reason being I don't think Robert would go through the trouble for a small increase to the 88mm and the 94mm would be to large and laggy. jmo but based off the fact that Mike pushed it really hard and barley broke 900 I would say the lbs/min would have been right around 85lbs/min in order to just break 900 and after punching some numbers, the size of the compressor would have to be around a 92mm to reach roughly 85.5lbs/min. We will just have to wait to see what it is...

in terms of spool
FP's HTAgt3582r > standard gt3582r > FP"s HTA gt3586r > billett 6262

in terms of max power
HtA gt3586R> 6262 > HTA gt3582r > GT3582r

 

the PTE6262 has a billet 62mm compressor wheel and a 62mm turbine wheel
while the GT35 has a 61mm compressor wheel and bigger turbine wheel
err .. any information why the PTE would spool slower.. im refering to the ceramic BB 6262 and not the journal ones.

thanks

 

Compressor and turbine diameter are just two of several variables that affect a turbo's spool characteristics, so comparing them between different brands of turbos is almost like comparing hp figures across different brands of dynos. Just looking at the diameter of the inducer or exducer doesn't reveal anything about trim, design efficiency, or the relative friction of the CHRA, all of which profoundly influence spool, transient response, and efficiency.

 

A GT35R has a 68mm-62mm Turbine wheel
and
A PT6262 has a 71mm-62mm Turbine wheel
and
A PT5857 has a 65mm-57mm Turbine wheel
and
A GT30R has a 60mm-56mm Turbine wheel

just to put things into perspective...

funny i was just about to post about these turbos and what u guys think haha if you dont mine instead of the 6262 i was looking at the pt6265. any thoughts by chance? i stuck between that 6265 and the HTA gt3586r for my next purchase

 

how about the PTE6235 ,
the compressor wheel stays as the 62mm , but the turbine wheel is a 35r

btw, how much do u all predict the spool up be comparing the 6262 with the standard 35r , few hundred rpms ?

 

hope to find someone on the 6235 , if any of u guys are on it, i would like to know, thanks

 

I think the 6235 will spool a bit better than a std 6262 however, I have not seen a dyno comparison. What is great about the 6235 is that you can use a garrett turbine housing and if you wanted too, you could do a 1.06a/r T4 Twin Scroll housing that should spool faily nicely.

i would say, thumbs up to PTE on their email support
i sent them an email , so looks like the 6262 is on ACBB and the 6235 is on garrett WCBB
aaron from PTE said the 6235 will spool quicker but its minimal
PTE ACBB can also withstand higher thrust

 

the 6235r is basically the 6262 but using a garret chra and turbine wheel. So you get the 68/62 35r turbine. (lamens terms its a 35r w/ the 62mm billet compressor wheel. In fact its basically what a FPHTA3582r is.

The 6262r doesnt use a 35r exh wheel, it uses the F1 turbine 71/62... which suggest potentially higher max hp w/ slight loss in spool. (this turbine seems to be the advantage for max hp and the main reason it may outperform the HTA3582 in all hp)
