Pte6266 Vs. Efr 83/74 : Quickest Spool/transient Response ?

[cobrAA]

PTE just upgraded their 6266 with their gen2 billet wheel and the turbo is now rated 800hp.. Personally, I prefer PTE because raw manifold dont need relocation and cost about 500$ less than the EFR kit.

However I heard great thing about the transient response of the EFR lines so I'm ready to shed more money if it's THE turbo to buy.

Goal: Quickest spool for a RB26 driven mainly downtown.

Power: AT LEAST similar to a properly -5s setup (575-600whp), but ideally, 600-650whp. No need for +700whp really... I mean, if both turbos could end up with 675whp, I will take it.. but as long as I have about 600whp, I wish to have the quickest one.

I got all the other supportive mods

too close to call. just buy one and focus on other stuff.

I don't want to comment between the differences as I have not directly compared the two, hopefully Lithium has some data he can share with you.

However bare in mind that the EFR can be had IWG and has been done on an RB26 by Full-Race themselves. To my knowledge boost control was sweet and the package worked well. If you are comparing apples to apples (BB to BB) the additional on the EFR is absorbed by the gates and additional plumbing.

Food for thought.

I will! I also sent email to both raw brokerage and fullrace.

Unless they stepped their game up I would go with efr

As opposed to all those EFR failures

As much as Precision aren't my favourite turbo manufacturers - at a glance there is a reasonable amount of dubious in there. Comparing their own turbo with something that doesn't come from Garrett for a start (since when did GT3076Rs come with T60-1 compressors!?!), the Precision 6262 etc no long run the same turbines as they did back then, the smaller hub area etc is a common billet wheel design - partly of the attraction for forming a compressor wheel using billet machining instead of casting is you end up with a stronger product, so you can use less structure without increasing burst risk.

I totally prefer the EFR8374 over the PT6266 though, and don't know of any recent EFR failures where things have been installed and used properly. There was a bad area way back when but now the only issue I am aware of is the turbine wheels don't like overspeeding, but that's easy enough to avoid by simple matching the turbo correctly and not being an animal.

I've got a 6262 and I think the EFR would provide better response... In saying that I would say that a 6262 is on par if not better than -5s

But the trade off are that they are too big, too ugly, too expensive and don't come in good external gate housing options for me

^ That's what keeps pushing me away #@SimonR32

The EFR's are too big/bulky/odd shaped. Love the Tech, but the packaging isn't right

I don't think they are that bad, a 1.05a/r TS seems like a good option But if you want T3, fair enough.

I think this looks pretty cool personally: https://www.facebook.com/photo.php?v=657790024292267&set=vb.217004505037490&type=2&theater

I would probably want one size down than the 1.05 in T4, actually if I could get my hands on one to see if it would fit I'd probably give one a go, but I'm not keen in spending over $2k to find out that I need to spend another $1500 getting a new manifold and plumbing

Saying it looks cool is the same as saying a Thai Ladyboy looks hot
