Full bolt on A4 car... (2000 C5)
Vararam, LS6 intake, LG headers, no cats, Vigilante 3200, FLP Level IV.

Car is 95% track, the other 5% is driving to & from the track, but I want to retain full streetability, so no roll bar, no big lobe...
Don't want to go too radical, as another .2-.3 is about as much as I'd like to lose in ET..

This is what I'm thinking, would like opinions & sugestions...

TR 224/224 @ 114 .563/.563
or
Futral FM-F2-114 224"/224" .588"/.588" 114LSA

Thanks for the help....
I would be using stock rockers, but upgrading to Comp 918 springs, chrome molly pushrods, titanium retainers, & also getting the Meizre electric water pump. Do not want to go with ASP or other pulley...

I think either of those is a great choice. You are definitely in the right size. A 112LSA, have you considered that at all?

I almost went with the FM2. The FM4 is VERY streetable, and it added 20hp to my stock heads.

YO-EL

iTrader: (6)

Not really considering a 112 LSA..
Looking for a pretty smooth/ stock like idle....

I'm kinda open as far as the FM2 or the FM4
Not quite clear what the difference is between the 226/226 .575
vs the 224/224 .588 both being on the 114 LSA..

Care to explain?

you should check out the y1 cam from mti. it makes great power on stock heads, is on a 113lsa, and should still be streetable for the size. i forget what the specs are, but they are similar to the tsp 233/239.

DavidNJ

With out a dyno, I doubt you could tell the difference between them. What is their duration at .200?

you'd have to check the cam motion catalog.

You do know that not all 112 LSA cams are radical, right? Look at this vid, it's my car with the F11 (228/230 .575/.595 112LSA). Almost idles stock, a lot of people complain becuase its not lumpy enough, but makes real nice power.

you really cant go wrong with any futral cam

f11 to f13 is your best bet and you will kick yourself later if you dont haha

Can't go wrong with any cam Futral cam.....

If I was you I would go a little bigger... you can even go a cam as big as mine and not lose a bit of drivability as long as you get the correct tune.

I was thinking like you - driveability, but I'm also concerned about emissions, here in CT. So.. I figured the FM 4 was as big as I could risk. I also liked the fact that the lift is .575 vs .588. As far as I'm concerned, every little bit helps in regards to the life of your springs. Some guys like getting their hands inside their engine often - not me. Do it once, do it right, and enjoy the results.

226 has a -2 * overlap
224 has a -4 * overlap

so the 224 has a better chance to pass sniffer with a proper lean tune.

the more negative degree of overlap the better chance to pass.

DD966

iTrader: (3)

Yeah, perhaps I worded it wrong. Obviously the FM2 will have a better chance of passing. But... I think the FM4 will pass as well. I think the others FM5 thru FM14 will be very difficult to pass, despite the tune.
From what I've read, the the FM4 will net me a few more ponies to the rear wheels (more than the FM2).

PREDATOR-Z

If so where in the rpms?? Is it peak? Under the curve?

First check you local emission laws and base your judgement on that. Not Hear say, but from the Lion's mouth.

YO-EL

iTrader: (6)

Not concerned with emissions.
I'm exempt... Car runs under 5,000 miles a year..

I am more concerned at having a smooth idle, & not losing more then .2-.3 in ET, because I do not want to put in a rollbar.

In 55 degrees I run 11.75-11.78.

I can go down to 11.50 without a bar...

So a cam that could net me .2-.3 in ET is what I'm looking for, but want it to idle as stock...

TR224 is the cam to run...
Get it on a 114 +4

zo6vetteman2003

iTrader: (1)

Just about the same cam spec as my comp cam.

YO-EL

iTrader: (6)

Whats the +4 mean..??
Didn't see that offered on the TR site..

JS

iTrader: (4)

Its on a 4 degree advance....TR224 is the best stock headed cam out there to date and it works very well with ported heads too

PREDATOR-Z

MTI Stealth II here, 224/220, .581/.581 116+0
Really idle like stock but with a nervous rate. Also in the same power range as the TR224. With that cam , you can drive more than 5K a year, it will pass sniff, visual, you name it. And still rival bigger cams on top.
