Im looking into the new billet wheel turbos from precision. Specifically the Precision 6262. There is a local evo running one making 740whp @ 42psi on E85.

Just wanted to see if any of the honda guys are using this thing.

 

The turbo is great. We had a 83mm GSR on the dyno today with one. Had a basic setup with GSR cams and a 6262 .63a/r Turbo. Made 536whp at almost 21 psi and 110 octane. I will post the dyno chart Monday. Turbo definately has 7xxwhp in it.

 

This is an excellent turbo. We put a SC6262 .82a/r on an 83mm GSR, stock head w/blox b cams. Spool time was 15psi by 5500rpm.

It made 503whp/318tq @ 15psi on 92 octane.

 

would like to see the chart im sure you've seen my thread about my gsr build.

 

We have sold a few of the new precision billet 6262, nothing but positive feedback!

 

Changing to a billet 62 right now, although I have a 6265.

Cant wait to see how it does on my setup new spring when retuned with couple other goodies.

 

I talked to a few people that said the loss of spool of the 6265 vs the 6262 was not worth it. I have not used one myself though.

Here is the dyno chart for the car I was talking about.



And some pictures..

Exactly what i was looking for!

 

^good stuff

 

well I am have a little more displacement to work with so for my application the 6265 seems to be more well suited to my needs... which may not be the case for the OP with a smaller motor.

 

Here is the video.

and yes it the owner of the car was very happy. You can hear him in the background. It was his first turbo car so what can you say lol.

 

seems interesting.

 

Some billet wheel goodness I just recieved, sorry little shakey so just slightly out of focus.

 

What is the advantage of billet wheel? I'm sure it's lighter than non billet ones but what else.

 

When I was at PRI I sat in on a seminar hosted by Garrett. At the end they opened the floor for questions and I asked their insight on Billet Wheels and Extended Tip Wheels. The Garrett Rep said that the billet wheel is solely a less cost effective way of mass producing compressor wheels. IF this is true, why is it costing us more to purchase these turbo's when it's costing them less to manufacture them? You'd think the cost savings would also trickle down of us guys to?

I am in no way implying that what the rep said was 100% true. I am just trying to shed some light on it and see what others have to say about it.

 

I used to have this turbo on my kseries... I loved it, but now that im building a bseries im trying something different. Turbonetics GTK !! QUICK SPOOOOL!!

 

You said he told you it is a LESS cost effective way of manufacturing... that means it cost the manufacturers more, and so subsequently it cost more for the end user. Lets say thats a typo or whatever... aside from that the new billet units are using redesigned wheels which take r&d, high end cnc machines, programming time, etc... in the end they will recoup this cost but they have alot of initial investment in to cover. Just like any new product.

I am going to have to say that rep. was leaving out alot of important facts.

Billet vs cast wheels. Billet is lighter, stronger, allows for more aggressive aero design, can tolerate higher tip speeds, smaller hub which means a billet wheel has more area than a equal size cast unit, etc...

 

Srry was deff a typo. I should've had my morning mojo before posting.

But the rep said it cost the manufacture less money to manufacture billet wheels over the standard cast wheels.

 

I figured it was and yes it probably does cost less for just the actual manufacturing a billet wheel. Also I would bet they can rapid prototype, test, and even make changes in designs MUCH faster and easier than traditionally what was done with cast counterparts.

The initial cost increase I think is for r&d, marketing, tooling and other overhead... etc. I think pricing will come down a bit as the market gets more competitive, initial investment cost is payed back, and whatnot.

**** wanna talk expensive, look at garrett's true billet units or other billets the diesel pullers been running for a while now... those things are some $$$.

 

I'm a lot more interested in what he had to say about extended tip wheels, what did he say about those?

I THINK than some holsets come with billet wheels, like i said i think im not positive but i remember someone in dsmforums saying something about what vehicle did the holset with the billet wheel come off of? And while im on this subject does anyone know the answer to that question what vehicle did the holset with the billet wheel come off of?

Also another question, how much on average do these cost? can you get a the precision 6262 in DBB form because i can definately tell from the dyno that the 6262 wa not DBB? If so how much do they cost and would you guys say the spool of the 6262 compared to the 35r? If not does precision offer something comparable to a 35r? I saw on evans that precision makes a 35e, jeff said it was a 35r with an e comp. cover but im not sure if it was actually DBB or not.
Also can you get a 35r with a billet wheel? and if so how much does it add to the price?

I wish precision would update there webpage on what turbos they offer its almost 2yrs old. Is there anywhere to see what they offer other than calling them? Sorry if i got slightly off topic but i would like to know more about billet wheels in general,

 

damn the difference in this car and the dyno of the other means that cam and going from a .63 to a .82 made a 62whp difference and the dyno of the car with the .63 appears to make 15 psi around the same time so those cams must be the bomb......which skunks are they copies of?

anyone else notice this? 62whp is a lot if the .82 didn't change the spool time then that means those cams are REALLY good

 

The Garrett rep just said that they haven't done any testing on those turbos to give a valid opinion and Garrett has no intentions to incorporate some kinda extended tip technology to their turbos.

 

a local street evo just went 8.9@156 on a T3 rear 62/62 780hp on 48 psi

 

It is my understanding that the GT-K's are garbage, which is why you see nobody with them in here..........


Dont the Billett Wheels allow a more aggressive pitch to the wheel due to their strength and I am pretty sure they flex less also at higher pressures, which allows an overall higher boost pressure over what a standard wheel would be capable of.
