Hello everyone,
Lately I've been debating whether I should change my hta3586 for a new 6466. Last year My car made 781whp @ 44 psi . Even though I couldn't enjoy the car too much because my trans took a crap twice from banging those gears. This year I want to break into the 800's that's why I'm considering a 6466 . Will the 6466 make more power? The entire setup on the car will remain the same the only thing being change is the turbo.

Here is my mod list

*Built 2.0l Manley TT rods/Je pistons 0.20 over 10:1 compression Acl bearing/
Arp main studs/BR balance shaft removal/Fluidampr

*Unported head /kelfold 280's/ standard inconel valves /supertech dual springs and retainers/L19 head studs/copper valve guides/

*Custom T3 hta3586 turbo kit/tial 44 mm/4" intake
*4" intercooler/custom 2.75" Uicp/ 2.5" lower/Tiall BOV
* custom catch can with STM fittings and dip stick
*Ported buschur IM/ Full Blown 70mm TB
*custom walbro 400 double pumper/aeromotive FPR & fuel rail
Fic 2150cc injectors/fuel lab inline filter.

*jacks transmission ultimate ratio trans & tcase/ HD Exedy triple/
STM fork stop & clutch line.

*spartech non cdi ignition
*torque solution motor mounts
*all buschur lightweight parts
*buschur small battery kit
*custom aluminum exhaust

I may be missing some parts but I can't remember now .

 

AFAIK the 6466 is rated to 900hp. I believe the 3586 is around 750-800hp if i remember correctly. The 6466 does have a bigger inlet wheel too 64mm vs 62mm on the HTA. I would say go for it with the t3 .63 ar turbine manifold side. BTW 781whp is ****ing sick. I think you should be able to make more power.

 

Thanks man, I know 781 who is sick but I always wanted to break the 800's. I can probably turn up the boost but my turbo will be on kill mode.

 

a t3 .82 would be the minimum hotside i would run on the 6466...

a .63 would choke the **** out of the turbo...lol

 

Off course, I will run t3 .82 vband . I will never run a .63 on a turbo that big because I will loose power instead .

 

Would be interesting to see the 6466 against the FP3794!!

 

well the guy who suggested the .63 does drive a cobalt SS..

 

the 6466 definitely out classes the 3586, the 3794 would be more of a comparable turbo to the 6466. either one will get you where you need to go

 

I think I will pull the trigger. Anyone wants to buy a nice hta3586r.

 

Yea, but you wouldn't want to run the turbo past 44 psi lol, that's just scary to do.

True, you are correct. I forgot in his power levels he will need the bigger turbine manifold.

Don't know why me driving a Cobalt SS has anything to do with that.

 

Fwiw, my car with a 6466 makes right at 900, and was limited by my ignition(SpoolinUP COP) from pushing it farther.

I'm only running Cosworth M2 cams, and the BR ported stock IM/TB too.

Should probably add, this is with E98.

 

Wow 900hp is sick . I'm going to buy the 6466 and give it a shot. I was planing to update the intake manifold to a new Ams f1 but, I want to see how much power the 6466 will make over the 3586 on the exact same Engine/setup. I think using a bigger intake manifold will make the car laggier because I have a unported head.

 

it'd definitely be awesome if you onyl change the turbo. the more direct a comparison the better! thanks for sharing, dude

 

Maybe messing with some cam tables after the turbo swap it can help flow even without a ported head. The manifold shouldn't make too much lag honestly. BTW do you have a dyno of the 781whp pull, I would love to see that curve.

 

I will look for my dyno sheet and post it up
