those are nice numbers..and those are exactly the amount of mods i would like to do...noting krayzie just a few u know..the mbc in ur opinion is it better than a ebc like Greddy profec or apexi one?

 

Thanks. Thats what I tried to do. I did the mods that I thought needed to be done, theyre simple (except for cams) but the cams added that oomph up top. That coupled with a tune is magic.

I went back and forth deciding on a boost controller. The cons with the ebc is that its expensive and you dont get spiking at all. Now most people woudl say, you dont want spike, but I think hitting 23psi then going to 21 helps torque and getting your *** moving. My car feels faster when it spikes. It immediately settles to 21 so no harm either. My hallman holds solid so I like it. Its really a toss up.

 

im not understanding why your saying cam gears are a waste of money.. its part of the basic vishnu staged upgrade.. and comes before cams. The evo already has decent cams to play with, its not like a dsm block.. so cam gears are of some benefit.. and have been proven to add anywhere from 20-30 whp with vishnus tuning behind them. So why are they a waste again?

 

For the sake of another viewpoint -

Cam gears allow you to shift your torque curve lower or higher in the RPM range. Obviously if you're making the same torque at higher RPM you're going to be making more peak horsepower. With stock cams it won't be anything earth-shattering but you might see ~10-20hp up top all things being equal.

The other thing cam gears can do (specifically, if you are retarding your cam timing) is improve your knock resistance by improving how well the cylinders fill at higher RPM's, where the Evo is more prone to knock. The trade-off is slightly less low-end/later spool.

Can't totally disagree with what's been said here, about cam gears not being the biggest bang for your buck (they make torque by removing it elsewhere), but they have their use.

The downsides to cam gears are the potential for problems if they are not degreed or tightened properly and the need to experiment with lots of combinations if you want to really optimize them for your particular set-up. At this point though people have had consistent success with Evos retarding both cams anywhere from 2-5 degrees.

 

Does anyone has opinion or experience with the possibility of passing inspections,
emission testing with cams in the evos? Thanks

 

The project evo on sport compact car has adjustable cam gears on stock camshafts. They retarded the intake and exhaust -5 degrees and I think they got some power out of it.
Heres the article, http://sportcompactcarweb.com/tech/0402scc_evosti/

Also, the vishnu stage 1 has adjustable cam gears as one of the items so they must be quite helpful.

 

No where in there does it show the cam gears made any more power. They said its there... whoopdy doo. They were combined with other mod and tuning. They said they went from 233 to 273 with exhaust, cam gears and custom tuning. Just because Vishnu has them in stage 1 doesnt mean its game, as much as it could be, I havent seen it, personally.

 

ditch the mbc and flash and spend the extra money on the XEDE. It will help with all future mods. My upgrade path is similar to yours.

1. Gauges
2. XEDE
3. TBE and fuel pump
4. Cams, Cam Gears, Head studs

I think around then I should be nearing my 350awhp mark. My goal is somewhere between 350 - 400whp. Then I'll be done with her I hope for the time being I'm trying to follow vishnu's path if you haven't noticed..

 

Ditch the MBC and flash? I have yet to hear that one. I believe custom flash is the way to go. I dont really believe the mail-in is as good.

I prefer to stay away from $1000 piggy-backs that dont ad any more power than the flash.

 

Well I was going to get the MBC and a flash then decided that the XEDE could take care of both of those. Nothing against the flash or mbc I just live 7-10hrs away from any type of tuner and this being my daily driver I can't have my car down while I wait for a mail-in flash.

Just something to think about

 

I guess that makes sense, since your far, but even so, the XEDE is quite expensive. I drove to get a custom tune so I had no down time because I need my car ever day as well.

 

cam gears without camshafts are a great mod.....and i agree with crusin lancer, forget those and go with the xede, you cant go wrong, and then the cam gears will be perfect for the stage 1 map

 

Yes it is quite exspensive, but Vishnu will sell it for $600 now if upgrade with that after buying other parts. I didn't go that route I ended up finding a nice guy on here from Georgia who was switching from the xede to the utec, just because a utec tuner was closer to him. I got a great deal on the xede and ended up saving over $350 . I don't want to start no tuner war here I'm just very happy with the xede, and the base maps they offer are great. Plus now that gas is on the rise, in the long run after paying for the gas to drive to get a custom flash and also paying for a new flash everytime you add more mods it adds up that the xede will save you money in the long run. Plus I'm a computer geek and anything I can get a hold of that can be tweaked with a computer I'm in.

I understand your point though if I had a tuner 20min away that could flash my ecu whenever I might have choosen another route, but I'm still very satisfied with my xede.

 

Well, on the old Vishnu site they had a dyno graph of the gains of adding cam gears and tuning along with nothign esle, and as mentioned, the -5/-5 setting merely shifts the torque curve up, netting higher peak HP at the cost of midrange torque. So yes, gears alone can net more power, but the combination of cams and gears is really where it's at. You can take a cam set like the 280's that have the duration for high RPM power, then advance them (not retard) to shift that power back into the stock block's rev rance and really make some killer torque.

Oh, and saying a piggyback is useless is an ignorant statement. Everything has it's use. For a street car that has an owner that doesn't like to change parts often or dabble with mods, then yes, it's overkill. But if you change parts often and like to run multiple maps then a piggyback is not a bad alternative at all...

I think you are better off with a flash because it's tune and done. You are not looking to keep making changes, you want to reach a particular level. I think an Xede is overkill for what you want to achieve and it doesn't sound like learning how to tune with the Xede is what you are looking to learn.
