GSC 280 cams results ? ? ?

[GokuSSJ4]

i notice that you guys recently tuned a IX with some GSC 280/280 cams. The graph was posted on the IX data base section that Tom has been working on.
My questions are what were the results on the 91 octane and how does it compare to before the cams were installled.
I would like to see an overlap of a before and after installation and tune with the cams on 91 octane (since the chart posted on the IX data base was on 100 octane, from what i read)
also feedback on how the power band has improved and in what areas were affected the most (positive and negatives)
thanks!

First, let's get all the facts on modifications:
Evo 9
Open ECUFlash by Alfred on 91 and 100 octane
GSC 280 cams
jic Full exhaust, no cat
turbo xs duel stage MBC
arc Intake
680cc
ams fuel rail
ams intercooler
Wideband Air/fuel gauge
walbro 255

an to add to the mix
here is the chart :)

where can i get a set of these cams O0

I'm pulling up the 91octane map now.

ok thanks goku

[GokuSSJ4]

do you have a prior to cam installation chart that you can over lap with the results with the cams ? ? ? Â*
from what i have read on evom, GSC claims results as high as 40lbs of torque .. it would be interesting to see on what areas Â*under the curve it shows similar results or the advantage of adding cams (not just for peak #'s)

[Smogrunner]

Goku,
Here is your car on 91 vs Rami's with the GSCs on 91. Your's is run 9, his is run 6:

You can tell that the intercooler is slowing spool down a little bit. Also, that ARC intake was making his car stall prone.

[v8hater]

If it safe to assume that the valvetrain needs to be upgraded too if one decide to install these cams???

BTW I am just going to get the same cams Thomas gets since I know he is a perfectionest, I will let him to all the R&D =P

[GokuSSJ4]

thank you smoggie :)
i have come to learn ( i know scot mentioned it a couple of times) that running an aftermarket FMIC on the stock turbo is pointless! since at the end you loose hp under certain areas. A big example would be this car and spool...
I wonder what those things would do to mine :) another 20-30hp+ 20+30tq .... hmmmm, LOL

LOLÂ* an to answer your question, no! valvetrain isnt required. you can run your stock valvetrain up to 8k without any problems.
Im waiting for the new cams that are being release this month. Once those things come in (i want to check out the specs first) i will decided what would seem like a better route for what i plan to do with project Mivec LOL :buck2:

stock FMIC is good for up to 400hp....

[Miss Evo8]

what does it matter Tomas what the specs on the cams are? you will change your mind 10 times along the way..... :roll:

[Miss Evo8]

Goku, What new cams are their coming out with that you keep mentioning. Is it by any chance the GSC S1 cams?



2nd batch of GSC cams are comming out... supposedly a bit more mild then the 1st batch..

[atlvalet]

It looks like the cams didn't help that much. Interesting.

[GokuSSJ4]

It looks like the cams didn't help that much. Interesting.
see, thats why i want an over lap chart of his before the installation of the cams and afterwards.. since final chart doesnt necessarly mean anything.. he could of had huge gains if his #s were low..
BTW the 2 graphs that smoggie compared was his 91 dyno graph w/ cams vs mine which i dont have cams and from the list that he mention, less mods... i dont have an 02 housing, fmic , cams, injectors, etc..

ill quote smoggie on this one... this is just a graph comparing his set up on 91 with cams vs mine
his mod list

Evo 9
Open ECUFlash by Alfred on 91 and 100 octane
GSC 280 cams
jic Full exhaust, no cat
turbo xs duel stage MBC

walbro 255
vs
mine
[list]
Turbo back (apexi Ti ) custom work
MBC set @ 21psi
fuel pump
and Alfred custom tune

[Miss Evo8]

well it looks pretty similar... not worth the money IMO... save your money Tomas....

[GokuSSJ4]

like i mentioned before his graph needs to be compare to his before installaton of his cams .... so you can see what gains he achieved..
an accordinly to the link from evom
here are the specs on the GSC S1 new revised cams for the IX since the specs on the previous ones were 280/280 (same ones on this dyno)

The Evo 9 S1 cams are just awesome! The cams are suited to the stock turbo and valve train. We have made the gains and are super excited for these to be released next week.

Spec’s
Intake, 268 advertised duration 217 @ .040 with a peak lift of 10.8 lift
Exhaust, 260 Advertised duration 208 @ .040 with a peak lift of 10.3 Lift

[Miss Evo8]

Bah! Save your money you would spend on those cams and do some track days instead!

[Smogrunner]

Comparing those S1 cams to Cosworth cams specs, It's seem that cosworth cams are the one to get.


The Cosworth cams are $500 MORE bucks than the GSCs when you add in the added expense of springs and retainers. More than $500 if you get the Cosworth valvetrain upgrade. I'd wait for two or three definitive, non-biased comparisons...

$500 more? i thought they were 600 even or less when RRE had them at an introductory price.

so gsc cams are only $50!?!?!

remember it isnt just about specs but about cam profile.. the profile can be a lot more aggressive (something similar to the Jun cams)

smoggie might think there 500 each...
when the price is in the 600.00 area for both...
an to ad to the post on valvetrain, cossie valvetrain is near 600.00 to be correct, not 500.00

[Smogrunner]

I should have been more specific and I went back and clarified my other post. I was under the impression that you were required to upgrade valvetrain with the Cosworth cams. Since next to noone has done this on the 9s, I figured that would add a considerable amount of cash to any nine owner looking to decide one way or the other.

[j_nizzle]

oooohhh....i see now what you mean.

springs and retainers for the cossie cams are require if you plan to rev pass stock rev limiter

[Smogrunner]

GokuSSj4,
I was comparing your spool up to other nines and would like to know what you did to have it spool so quickly. No kidding look for yourself. It was probably a mistake to compare your car to the GSC car, as you have the fastest recorded turbo spool up of any 9 ttech has dynoed..

Really.Â* O0

Using power recorded at 3500rpms:
Whp------Wtq
210--------310 = Goku
190--------285 = ~ Average (eyeball guesstimate)

[GokuSSJ4]

hmmm, BOV can perhaps hold boost or allow boost to come on quickly! since i notice the same results (back to back on an old car , old set up) by switching BOVs...

Interesting you should say that. You had the fastest spooling Evo8 I have come across as well....
215whp at 3500
320wtq at 3500

now, don't just run around with a chubby all day, help us figure out what you did to achieve that

Forge RS BOV ... damn it ! now im keeping it LOL
what led to this discovery on my 05 viii, it was just a boost leak test (to make sure the BOV wasnt leaking) and when Alfred did a back to back run, we saw the different BOV (Forge RS) hold boost a lot sooner then OEM piece (this was my reason why i bought this brand of BOV) the OEM BOV was fine, problem wasnt on the BOV but something else. but the results were showned when the car spools

[fusionchicken]

hmmmmmm interesting bit about the forge rs bov......
