Too much llift???

[Naf]

I did some talkin with my friends and i found out my GTS cam will take an additional 2 weeks before delivery so tats a total of about 3 weeks for my Aussie cam.

Didnt want towait that long so i made a few phone calls and some options were offered to me...

GT2-3
GT11
CCA 444
ESC custom
And so on...

I said no to the GT2-3 for everyone here that i know is runnin it...Couldnt have that. So i discussed about the other cams offered. The CCA 444 was a little to lopie for me. Hear a car with it here with similar setup...

The ESC had a month lead time, and well like my other cam i declined...

I talked to my friend in LPE and he suggusted the GT11, i asked if iwould have any issues with clearance, but he said no, and i keep my stock idle sound. The only part i find uncomfortable is the massive lift. 631 644 THATS MASSIVE. i snooped around LS1tech, and some people are runnin this type of cam...

I talked with my friend here and i still couldnt get over the amount of lift...I am freakin out here...

Help, someone here must have run this cam or similar...

[Naf]

What i forgot to mention was i would like my car out of the shop by X-mas...Want to drive down to Dubai for a little track time. But i am not closin up the engine without puttin in a cam...This is the whole reason for the start of this little tear down. CF fenders, and rocker panels...DHL dropped the ball on my CF rocker panels so i am waitin till they show up before i remove my stock ones....Sorry buddy, you will get them soon...

Naf,

Make sure you mention that you have higher compression heads (I assume they hgave been milled a bit), and let them know what sized head gasket you have as that will affect how big of a cam you can get without flycutting.

That sounds like an awefull lot of lift, however I'd be most concerned about what type of lobes that sucker has. If it has a very agressive lobes (I.E. the ramp rate is very high), it will be hard to control unless you use very strong springs.

If you get supper agressive with your lift and ramp rates, then you are going to need to swap valve springs more often. If you don't put a lot of miles (er KM's) on the car then it doesn't matter as much. I'd also consider getting a nice dual spring set, just for the added piece of mind of having the 2 springs. If you do break a spring, with the duals you will usually have enough time to pull over and shut the car off before the engine eats your valve ($$$$), whereas with a beehive single spring, the valve gets chomped ASAP.

If I were you I'd consider working with Partick G over on LS1TECH and have him spec out a custom ground cam for you. You can get the grind done by Lingenfleter (since you know someone there) fairly easily. They ground mine for me. If you get a custome cam, you can get exactly what you want. Especially given that you want it to be 'different' but not also scare away every girl in the area. Just tell Patrick what you want.

Glad you came around to the idea of getting a cam

Naf, post some pics of your V in Dubai

EDIT: by that indoor ski resort if possible......hell any pic downtown would be badass...they have some awesome buildings!

Valve event timing is more important to PTV clearance than lift measurements. I also agree with getting custom speced cam for your application.

yes that is alots of lift if u have a stock engine,it might be hard to tune,u might need bigger fuel injectors and a maf sensor that will read more air,if ur engine is build for low comp than u will be fine

Chris,

The engieers at LPe know everything i have in my block...I have the MLS head gaskets, with HC heads. I even informed them of my cr which is at 11.59:1

I am goin with the double springs from cca...921s if i am not mistaken...

Now would you like to see the pretty girls in the picture for they are extra charges...Or just the buildins?

As mentioned above, i am pretty high on the cr. I called my friend again just to reconfirm and his re-assured me that plenty of people runnin a similar setup have installed this cam with no worries...

Our cars already sound like sewin machines, so i am interested to see how much more it is amplified...

Worse case i take out the cam...

As for tunin my friend at LPe is gonna hep me out...Since i am basically runnin their top end...And intake kit, and i bought most of my mods from them...

[atdeneve]

Naf, have you had a chance get a run on a dyno yet? Curious as to what numbers you're puttin down and your gains seen.

[Naf]

i tired but my car doesnt liked the dyno...Gave me 9 degrees of Knock retard, and the torque curve didnt work, my PS fluid over flowed, and i did see 325hp at 4500 or 5000 but i dont remember...

I took it on the road with the exact same tune and i saw less then 2 degrees of knock retard at the same rpm...

What can i say she doesnt like to be caged or tied down like me...I have to admit though, i can feel the increases. I had a good tune Stock stock. Then when i had the cai headers and catback it felt great...When i put the heads, intake manifold, and no tune she felt a little weak...Fixed up the tune a bit and it openned up...

Now with the new cam i feel i aught to get 420ish hp with about 400ish of torque. and a nice flat curve to boot. This is what a friend of mine here said about his GT11. He is runnin a 408 with 72ccAFR heads and ported fast 92 intake and made 485/475 with a vertual flat curve.. He is happy...

[Bueller]

I doubt you will get 95 hp out of a cam and retune even if this is the one part your motor needs to work well.

You're building a motor that will have a steep curve with nice peak power and less mid and low range, not a flat torque curve. We all can't wait to see the graph.

Enjoy. Lets see some pics...

9 degrees of timing could be worth 50 rwhp easily. Not saying that is the case here, but it is possible.

[Naf]

I have to say its all in the tune...I have everything that may point to peak, but to be honest you never know...
Heads are 250cc intake runnners with 85cc exhaust with 60.7cc combustion chambers
FAST 90/90
GT11
LPe/Volant intake kit (May change to OTRCAI)
1 3/4 SW headers
Ti Corsa Catback 2.5"

It's all about the combination, or which the tune is a part.

P.S. There is no such thing as an OTRCAI, and anyone that says they have one is full-o-crap....yours truely the bolt-on

[Naf]

You would be surprized what i can find talkin to my friends...

Its all about information and bein in the right place at the right time...

Give me some time, i will get you pics of this mysterious OTRCAI...

LOL, the OTRCAI is just a dig at Jon, who has one.

I wasn't joking about eh combination though. You need to really sit down and talk with someone and really plan out your mods. You are all over the place.
