cams ?

[kevbojunior]

ok i searched on here and found some stuff, old stuff and just wanted some new input. i was thinking of using gsc s1 or fp2 cams. can anyone supply and knowledge or experience with these cams.

On a different forum a guy went and did back to back dyno testing with GS2,BC,HKS,and FP2'. The GS2 cams put out more HP than the other cams. They where really close the the FP's on the way that they make power. I have a set on my talon but it is a matter of a couple weeks before I start the car. So time will tell.

Your first choice is going to be what duration you want...because the s1 cams are 264 and the fp2s are 272.

ARFWD, can you provide a link to that comparison? I think that would be cool to see.

 

[kevbojunior]

you are gonna run the fp cams?

 

[kevbojunior]

different sites show different durations. for example one site will show the s2 to be a 272, the other will show it to be a 274 and ive heard 270. for s1 i heard 265, 264 and 268. Are their different lines of the gsc cams?

Here I can't post the link to the forum. You have to be a registered member to login. Which means you have to have DSMlink to sign in. I wouldn't jump on the GSC band wagon just yet though. The guy doing the test had some engine problem after running the HKS cams and had to rebuild the head. He said the compression was the same after the rebuild. Then while he ran the GSC cams he ran into another engine problem and had a bad compression loss. The HP numbers with the GSC cams was low like 30lbs less than what it was with the FP and BC cams. He ran the cams in this order HKS 272, FP3's, BC280, and then the GSC S2.

Here check out this link for the cam specs:

Mitsubishi :: GSC Power-Division: Racing Inspired Products

The specs on this site matched what the cam card said that came with my GSC S2's

On my 98 GST i used the HKS 272 and they worked out great. My buddy ran the fp2 and loved them as well.

Are the FP cams just Comp Cams?

 

[1qkfwd]

No I believe that FP uses there own grind on there cams. Its been while since I researched this so I will have to find the info I came across on the two grinds.

 

[kevbojunior]

i really just want the best cam for stock springs. i dont mind rough idle either.

 

[PIMking]

How many miles are on the head?

I have heard of people running BC272's on stock springs but I wouldnt do it.

BC cams are good cams for the price. But your going to have to have them degreed and that requires Adjustable Cam Gears.

^^Not true a local is running bc272 cams on stock springs and lots of people including me are running them without cam gears. I noticed more power and higher lbs/min on my link(42lbs/min at 18psi). The guy I mentioned above runs 11 flat at 136mph on an fp3065.

 

[kevbojunior]

the head is coming right outta the machine shop. i will probaly run stock cam gears.

 

[1qkfwd]

There are a few cams that you can run on your stock springs. I am running the BC 272's in my daily driver with stock springs. You will be ok if you are not going to see crazy rpms. I have raced this car like its going out of style and still no issues. BC will be the best bang for the buck cam for you. If you don't mind spending a few dollars more there are other cams that you can run that are compare able in size so you wont have to do the extra head work. I had to run cam gears with my cams though. That is not always the case. My valves where tapping the pistons because the cam timing was a little off. I degreed them and they where 2 degrees to far advanced. Now the car runs a lot better.

 

[kevbojunior]

yeah those are pretty cheap and alot of people run them. how about gsc s1. ive heard some good things about them and my buddy has them in his evo. Hes gotten great results but then again i have an eclipse. i am lookin at the fp2 cams as well.

Well, Its recommended. If you search some dont and some do. I have comp 100200 cams and AEM gears installed strait up.

If you want to spend the extra cash over the price of the BC's I would say it is a toss up. If the S1/FP2 is anything like the S2/FP3 the power curves are very similar. I have heard though that the FP's have a lumpier idle over the GSC cams.

 

[kevbojunior]

are fp2 very lopy. my buddies evo has gsc s1 and they lope pretty good, close to another friend with an evo with hks 272. How is the performance on bc 272 vs gsc and fp. Alot of people seem to like them. bc cams i can just drop in and tune correct?

 

[90laserRSfwd]

Does anyone have a cam card for a set of GSC s2 cams (s2's for the evo 1 - 3, aka 4g63 dsm)?

They are all a drop in cam. It is an added benifit to degree them to where they suppose to be. If the 272 series cams made by BC,GSC, and FP are anything like the 280 series you will get a beter gain out of the GSC and FP cams. I for one love my BC 272. When I first got my car running. I went to the track had a few issues with the car, but with 5lbs of boost the car made power all the way to my 6500 shift point. I managed to run a 14.0 with a broken rear axle so I was in FWD mode with 2.3 60' and spinning. That was with the cams installed with no cam gears. If your are on a budget go with the BC cams. If you have the extra cash it would be worth it to step up to the GSC and FP. They are all good cams. I will add though that the FP cams are going to be a higher RPM cam than the rest so take that in consideration.

 

[kevbojunior]

yeah i dont mind spending the extra money. it was just a matter if i didnt have to then i wasnt. So from i hear the gsc s1 are very comparible to making the same power the hks 272 and the fp2. is this true?
