I was thinking about something bigger than a 224 and I came up with this as a custom comp cam. Anyone have any numbers?

Its a 228 on XE-R lobe (.588) and 232 on an XE lobe (.575) on a 114. I coulnd't find anything by searching but I did find that MTI just came out with the G1 which is very close to what I am interested in. I wasn't considering the 113 LSA they have it on but maybe it would work. Still couln't find anything however. I am looking to hit 400hp with nice drivability and idle manners. Don't want to do spring changes every 10K either. Any input?

 

I don't think anyone is running a cam with that sort of split to it, in that range. But it'd definitely be an interesting cam, I think you'd have a pretty good chance of acheiving your goals and still surpassing the 400 mark w/o worrying much(people with well planned setups hit 400 with 224's these days). Try it out and let us know how it goes!!! Even better....try it out on Cam Motion lobes....they might fare a little better on the springs if you're that worried. Talk to Allan, he can help you out with that one.

 

You can get a cam ground to any specs you want sometimes cheaper then they get sold.

a tr 224 is recommeded to change the springs at 15k intervals... i had like 25 on mine and never had a problem though heh.

 

I was actually thinking about a FM11 or FM13 before this and I don't know why I leaned away from them but I think I saw more numbers below then above 400. Maybe giving FM a call might help. I've always been kinda patial to Comp lobe profiles though. I just cant decide and its making me crazy! I am ultimately trying to set up for H/C with the AFR 225s but also cant decide whether to do a cam first or the whole H/C swap. Ugggg! I want to do all the work myself and have a week at Thanksgiving and about 2 during Xmas off which makes for perfect car time.

 

Well if your wallet can survive it, try to do it the heads/cam at the same time. It avoids duplicating work, some of it very tedious(especially if you're re-using nearly new valve springs). Tony @ AFR should be releasing some news about the 225's here very shortly. Definitely give Futral a call, they can help you out with both the heads and cam.

 

I put about 6-7 K on it in a year because I use my other vehicals but I still would like to stretch it to 20K or 3 years. I love driving it and do so to work about 2-3 times a week so I need it to drive well and if I get stuck in stop-and-go traffic, I need it to behave (with a good tune of coarse). I figure this is the biggest I can go although I get the impression (through hearsay and what I read) that some of the 230ish cams (etc. TSP 231/237, TTP, LG3x) are becoming more drivable. However, I would'nt want to take that leap until I tried something smaller and experienced it myself.

Did you actually check the spring pressure or just do a visual to deam them OK?

 

Although I haven't ridden in one, nor have I driven one, people on the boards are getting bigger and bigger cams to be streetable. its all in the tune. LSA has somethin to do with it too.

 

I agree, I don't feel like changing springs only to do heads soon down the road BUT it provides a new baseline for me to dyno, tune and track test. Don't want to try and diagnose why my H/C combo is only getting 420ish without knowing where my starting point is (cam only). Too many variables. I am anxiously awaiting any 225 news. Called them about 3 weeks ago and they said another 4 wks. I can't wait.

Money is not really the problem, neither is paying for a professional install, BUT I want to learn, do it myself and have that satisfaction. If I want to pursue a H/C soon, I don't want to just throw on the heads with a cam. I will have to consider how much to mill, hand finishing, intake port matched and flowed with the heads, P to V clearence and possibly flycutting the pistons (beyond me - don't think I can do that) . Alot of stuff to do just to get the right combo.

Sorry about getting off track sooo Anyone have this cam or something close TR230?

THanks

 

True, the TR224 and the likes are become the "mild" cams now. Saw a guy at the track with it and he said its toooo drivable - he drives it everyday and he was planning to upgrade to a TSP 231/237.

 

the TR230 is 230/224 575/563 111.....not quite the same as what you're lookin at doin. concerning the dyno/track results.....cam only, then h/c.....its up to you. if it were me, i'd want to do as much as i could at one time. but i'm in college so i'm not rollin with the fat bank notes lol. i get to be thrifty!!

 

I had something made that was very simular....
it was a comp grind....228/232 .568/.568 on a 112 lsa
My set up was in a '98 Z28...that cam, CNC'ed 6 liter heads, ls6 intake, hooker long tubes/orp and a cutout after the y-pipe, magna flow muffler,spec 3 clutch, and tuning. My computer kept giving me issues kicking the car into low octane tables, and pulling like 10 degrees timing, but anyways, it put down 432/418.
I bought the setup used from a friend...He didnt have the pcm issues i had and "supposivly" put down 448hp and 431Tq...."supposivly."
I loved that cam...sounded mean as hell and had a hell of a top pull to it. Screamed from 3200 to 6600-6800 where ever i shifted at...Made power up there also.
I just recommended it to a someone else that was looking for some nice power.
hope that helped.

I am eagerly searching and searching for some detailed numbers or graphs on the G1 cam, but so far cannot find anything. I called them and they said that it was designed for mid range power, much more mid range than a 224.

 

More performance has that cam on XER lobes and it will definitely be my next cam. FWIW I currently have a comp XE 228/230 .571/.573 on a 112(off the shelf cam available though there catalogue) and it is simply awesome. On my Z06 cam only it put down 423/399-that's stock heads and valves, with headers and a 3"xpipe no cats. With cats and TPIS headers the car would run 11.60@122 with a high 1.85 sixty on DR's and a easy launch. It has a nice lope and has no driveability issues-it just works.

 

Same here, i went on MTIs website looking for a cam this morning. the G1 is what im looking for but i want some feed back before i get it.

 

Anyone who'd like dyno graphs or other information, please feel free to hit me up directly with an e-mail davidc@motorsporttech.com

I'll be more than happy to e-mail you some dyno graphs from various installations we've completed and answer any questions you might have.

The G1 comes standard on a 113 LSA, but it is also available on a 112, 114 and 115 depending on your preference!

Thanks and best regards,

I've found a couple now, but more info never hurts.

scottfett2000@yahoo.com

thanks

 

I just sent you an email....

 

youve got more mail

 

see cam specs in sig. the cam has XER lobes. i put down 398rwhp and 375rwtq. ive added a ported TB and ASP pulley since then, so i would hope those 2 mods gave me at least 2rwhp.

 

Nice numbers....hopefully that put you arouond 410hp, estimating a conservative 5 rwhp for each. What were you numbers before the cam? I'm hoping to get 40 hp out of it. If not, I will go with something bigger.
