6262 DBB or 6265 DBB?

[meanchicken]

Congratulations on your new turbo .... I love my 6265... get it back on the road and get us some more kills. :biggrin:

About the time I get it running again....I have to leave the country for a couple weeks between Thanksgiving and Christmas....so it might be awhile before I register any kills.

I usually don't have a hard time finding a victim or two.....

glad to see you went with a new turbo. cant go wrong with either.

 

[Mr.Spool]

that 62/65bb is a nice turbo for the street.

Hijack time.

Just curious about either the 6262 or the 6265. I suppose the difference between the E cover(3" in 2" out) and the S cover (4"in and 2.5" out) dramatically changes the flow charactheristics of these tubos.

I am looking for some information of the pros and or cons of each cover. If you happen to write why you chose one cover over the other would be apreciated. From what I read the S cover when ported helps with the boost creep was wondering if there was other reasons why one cover is ideal over the other?

Thanks,

Scott

hope this helps you some. this is what patrick told me..

E cover (3" in, 2" out)
S and SP covers (4" in, 2.5" out)
H and HP cover (4" in, 3" out)

On a Buick application, you will never push the turbo hard enough to see a significant difference in charge temps. Meaning, you would need to run the boost over 40psi in order to see a real difference in charge temps between the 3 style compressor covers. You'd blow the heads off the motor before reaching 40psi on a production 8 bolt per head motor. The E cover will work with pretty much all intercoolers out there. The S and SP covers will have a slight off set on most stock location intercoolers. And the H and HP covers are not meant to work with stock location intercoolers. The alignment is really bad on that combination. With regards to the 6765, I always try to spec a SP cover if the car is to be driven on the street.

Sounds good thanks for the insight.

How much is that offset.
I'm running an old school eastern FMIC and the pipe for the turbo outlet comes up pretty much in the stock location, but has a little play that should help with minor offset alignment, just wondering how much offset there is and if I need to worry...

Talked with Patrick a little while....my new turbo is in the mail:biggrin:

 

[Scott87]

I would imagine but dont quote me on this if you wanted to go 4inch and an zo6 maf you would need an angle boss for your IAC sensor since it would be a tough squeeze with a SLIC. I can this something to have to make provision for if you decided not to have to use step down couplers.

I am sure someone would be able to chime in who has some real world experience with this and a SLIC. Would be good to know.

Here's my 6265S (4" in 2 1/2" out) dbl BB, with a 4" Mark hueffman intake, LS1 MAF, and V4 slic. I did need a 45* adaptor for my IAC. My 2 1/2" compressor outlet and slic lined up perfect. Was told by Precision that the 3" compressor outlet would not work with a slic with out extinsive mods done to compressor and intercooler.

Now, quit screwin around and get that Chicken sled back in the Kill Section.

You need some dirt and oil on that engine.
Let me drive your GN for a month.....I'll take care of it for you....:biggrin:

Hey...did you find the cash I left at your shop for the header welding?

Heck, that money got spent on beer, hours ago.

You biter why did you get the same turbo as mine! Lol. Yeah with the champion ported goodies the car woke up like a champ. I can even break loose the 15x10 M/T tires. See you at the track one pollito...

HA!:biggrin:
I wondered when you'd chime in.:biggrin:
Hey....you copied me first!!!
Yup....we're gonna have to line these GN's up. We are pretty evenly matched other than my roller cam.
But your Champions prolly have an edge over my stocker ported heads...

"Biter" I haven't heard that in decades.
Me and my motorhead buddies used to call cops "Biters" whenever they wrote us tickets back in the late 70's:biggrin:

 

[Flaco]

Hey going to Lous is not being a biter! It's a wise investment.

Agreed!

 

[meanchicken]

It's here. Very nice!

I'll need to port the WG hole and clock it before installing. I also need to get a 3" to 4" angled reducer to go between the turbo and MAF pipe.

I'm also retorque-ing my head stud nuts, and have had the cracks in my headers welded up to address those leaks I've had for so long.

Here's some pix.

 

[turbocop294]

Nice! Makes me want to do a little shopping for my car. Please let us know how well it works for you.

So THAT's what it sounds like when you blow off an intercooler hose

:redface:

After being out of country for a couple weeks, I finally finished installing the 6265
I ran the WG actuator all the way out until it was just shy of the WG arm and went out for a test drive.
I maxed out the fuel in the chip and also the alky until I know how this thing is going to boost up. I'd rather be fat then lean.

I slowly rolled in and watched as it built the boost....up....16....17....18....POOOOOOSSSSSSSHHHHH!!!!!!

Scared the crap out of me!

Fortunately all it was was one of my lower IC pipes. I didn't clamp it tight enough after reassembling while jet lagged so the bugger blew off and gave me a big ol' "HOWDY STUPID!"

Since it was dark out and the hose clamp was MIA, I nursed it sloooooowly back home (about 1/2 mile) and fixed it.

Up and running again and I did a couple TNT runs. Tightened the WG rod a turn and am making about 21 lbs of boost and the O2's are well over 800 with zero KR, so some tuning will make even more power.
I also am running the actuator "tuner style" without the RJC controller for now.

It does creep a little, so I need to port that WG hole a little more liberally before adding any more boost, but MAN does this thing pull:biggrin:

Can't wait to kill something.:biggrin:

 

[Quik Six]

Make sure you have all the hose clamps tight. An up pipe being blown out of the TB at 30+PSI will screw up your hood insulator.

Interested to see how you like the turbo. I'm satisfied with mine but last week I was thinking that a 65 turbine with a compressor between the 62 and the 67 would be awesome and I read Sunday night that PTE has already answered the call.

 

[meanchicken]

Yup....after that IC pipe blew loose, I double checked the rest. The one that blew off is actually the weakpoint in the plumbing. The pipes don't line up perfectly and there is an angle forced into the hose as a result.

I need to get a longer hose there so that more meat is on the pipes to clamp to.

I'm also trying to get over the fact that I mispelled "STUPID" in my previous.....:redface:
Jet lag is a terrible thing....
