S468 v.s. S472

[Redbowties88]

so, im dipping money little by little into the turbo fund and figure i would start discussing options with everyone:hug:

def want a BW (for cost reasons) but im not sure what way to go, truck rarely tows so im not worried about that but ill be honest and say im a bit of a street racer so spool up is obviously important (for rolling starts). i do plan on an engine build but not until down the road a little. at that point i would probably just add a big boy underneath

basically looking for,

max power available T4 s472 .9 A/r v.s T4 s468 (A/R??) .9, 1.0 1.1maybe? also the 68mm does not offer the ETT wheel by the looks of it...not sure how that will play out.

also a possible spool up comparison? stock injector/pump truck (for now anyway)

thanks


EDIT: also forgot to ask what effect a race cover would have on spool-up.

from have what I have heard the race cover improves airflow by 15-20% I have one with my S475... I'll let you know next week how it goes

 

[Redbowties88]

thanks nick, i understand how it improves airflow however im wondering if the larger volume would take more time to fill if that makes sense

thats just my brain rambling on and its probably a stupid question but something im ignorant of nonetheless

Its my understanding that the only difference between the race cover and a normal cover in the mouth of the intake. Shouldn't take anylonger to spool and should only help, kind of like putting a bigger intake tube between the fliter and turbo.

 

[Redbowties88]

Yes but isn't the entire cover including discharge larger?

If you're talking about the Bullseye race cover then I believe it has a larger AR than the BW cover. I say go with the race cover, I didn't see a difference in a twin setup as far as spoolup. The only downside would be cost and the 5.5" inlet, the 3" compressor discharge would work nice with your 3" intercooler tube though.

Here are the two side by side, Bullseye race cover is on the left.

Does the race cover always have the slip fit discharge and the non race cover has the vband discharge?

 

[Redbowties88]

sweet, thanks for the side by side scott, def looks much better.


does anyone have any input on the 68 vs 74 question?

you have it backwards... the Race Cover has the v-band outlet

 

[Smokin LB7]

Thats what I figured it would be, but Dmax15 siad that race cover was on the left

 

[ripmf666]

The race cover comes both ways. The v band is 4.25 outlet on the race cover and intake is 5.5. The ex ar size is were you can kill yourself on spoolup. Once you hit around 550 you might want to think about a spare block the rods will hate you. We will see how long Nicks lasts with the S475 I see if he hits 11.xx he's pulling and building it if he doesn't god only knows what he will do to it lol Nick. Aslong as he out runs the flamer gmc buddy :spit::hug:

It is.

 

[Smokin LB7]

It is.

So the non race cover has that bulge?

Also, does only the race cover come with a 5.5" intake?

 

[skintback]

I'd go with the 68 and twin it after the built motor

 

[paint94979]

the race cover i have must be a Borg Warner

Spray it Nick, and sell the nitrous kit very cheap to me after it doesn't make 11's and you give up on diesels all together :spit:
