Hey i was wondering what kind of gains would i get if i ported my stock SC? The car is completely stock except for an SLP catback. Any thoughts or help would be greatly appreciated.

 

use the search button or google there is information on here about it you just need to look

 

you would get hp gains, torque gains, iat gains (iat loss if you wanna be technical), noise gain (for the ricers), etc etc etc etc

 

Wouldnt it be easier to just pulley down?

 

Pulleying down just creates heat and with no cooling mods(OPs car is stock) wouldnt be a good idea..Pulleying down requires supporting mods especially injectors..porting the blower is good but I would think u would need a ported head too to get all the benefits..just my opinion

 

we have not seen gains from porting the stock blower. Only losses.

 

aparantly you all did something wrong we have seen iat drop and hp/tq pickup on a ported blower

 

Agreed!

Ported right, there are gains to be had.

 

You can pulley down on a stock car...

Gms2 didnt have any cooling mods with it did it?

 

idk if rhetorical or not but nah dog it didn't

 

I've posted the proof multiple times, the gains are there.
Dual pass was intended as part of the "stage2 package" iirc.

 

f*** cooling mods. slap some 60s and a 2.8 and be happy

but expect to be a hair slower in the summer lol

 

You cant pulley down much on a stock car due to the injectors alone which are damn near maxed..but no stage 2 doesn't include cooling mods but does include 42# injectors..can't hurt having cooling mods as increased iats and heat soak lead to pulled timing leading to power loss

 

This. Eaton has said the same thing back in the day.

 

Well ZZP probably started outsourcing their porting to China. That's probably why they saw no gains.

 

Nah, it was always intended for the s3 package, but could def be used to maximize cooling for s2 cars.

 

this

 

 

what is so funny

 

Post dyno results before and after. too many variables otherwise

 

Just ironic that you would call out the company that pioneered the very mods that made these car's capable of such high hp, of being unable to do something right.

 

Wouldn't be the first time.

 

Lol

 

back to back same day results were posted by alan they are on here go look and also flit and euthinasia did th same thing and shown positeve results

lmao

zzp has pioneered the closed deck ecotec block that is their greatest contribution the turbo kit is nice but otheres done that before zzp did and they gave up on any development on the lsj when the tc came out is it possable zzp has gotten some stuff wrong yes it is im not saying they are a screw up company ive got a couple things on my engine from them they do have nice stuff

 

aanyway you can gain what, a good 5-10 hp if ported by almclure haha. worth it for all the reasons above, mine is ported and definately picked up some noise, but that was also from plugging the silencer holes... which are holding up great
