hey guys i really need you input so i dont go wasting money. im looking into doing a pretty potent head and cam for a daily driver all street. its gonna be on an auto. im looking at either mti 2e and their x1 which specs like 230/227. or g5x1 with afr 205? which would make more hp and which would i be happier with? and also i plan on running a 3200 stall. either vigilante or yank? thanks

 

as far as the converter, did you look into fuddle? custom built tc's.

i gained 100rwhp with my heads/cam package and it is streetable. you might even do better w/ afr's.

 

im looking for atleast 415rwhp through an auto. im sure its doable. at first i thought about going 224 cam. but i figure most 6 speed guys make 380 on stock heads. so i figure a 224 cam on an a4 would be 360-370 maybe. and with heads i might only make 390 or so.

 

can be done with proper tune. im at 407rwhp now. thats without the ls6 intake

 

Getcha a big cam....don't be scared. If you want a beast get a T-Rex. I basically have a milder version of the T-Rex myself. 244/248 .600/.605.
With that cam and stock ported and milled 50 thousandths heads I was seeing close to 80rwhp in the 5800-6700rpm range.

The only problem with a cam that is that big is you will need a 4000 at best if you dont want it to be a dog around town.

but a 224 is a safe out as well. broad powerband.

 

the 224 with ported heads through and a4 will get you probably 390-400hp depending on the condition of the engine before the upgrade and also the tune.

you have to realize that cams/heads add a fairly consistent amount of power. meaning the same cam installed on 5 cars will yield approximately the same amount of hp GAINED....not final hp number.

some cars....often called "freaks"...just dyno higher than others. so a cam/heads setup that will gain you 75hp could prove disappointing if you car is only producing 300rwhp to start. compared to someone else's car that may be starting from 325rwhp.

if you want 415 at the wheels, you'll need to go pretty big. i would look into the Futral cams, they are pretty much top of the game when it comes to cams.

the F14 is a pretty potent cam, and should get you the desired hp with ported heads even through the A4.
FM1-F14-112
FMS Custom Grind Camshaft - 232"/234" .598"/.598" 112LSA - aggressive profile with a 3000-7000 RPM range, rough idle

or you could go crazy and step up to the Ron Jeremy cam
236"/239" .600"/.611" 111LSA - aggressive profile with a 3500-7200 RPM range, rough idle

i beleive Kraest is running the RJ cam in his C5 with stock heads and some boltons...through the corvette drivetrain he's putting about 415hp to the ground

 

im really stuck. im looking at going all mti heads and cam. their 2e and x1 to be exact or g5x1 and afr, or playing it safe with a 224 cam and afr 205. its all street. im not trying to hit 10's. just all street. i would also like a setup that would blow away 03-04 cobras?

 

the 205s are a good choice for street. you'll maintain good low and mid range power.

but i think you'll be disappointed with the 224 if you want your previously stated 415rwhp...specially through an auto.

 

One thing to keep in mind when specing out a large cam with aftermarket heads is P/V clearance. With a large lift and bigger valves, you may be cutting it close on stock pistons, especially if the heads are milled. Make sure you consult with the vendor you're are purchasing from to determine if you may encounter P/V clearance issues.

 

Good reasoning, "don't be scared". You recommended the TR224 or the TRex cam??? That's like saying I recommend you date Brook Burke or Rosie O'Donald.

A very important attribute is the excellent head choice, AFR heads. If this was a T56 car, you could get your goals easily. There's a guy on tech who's made above your target #'s with only a 221/221 cam with heads. You're not going to have to go quite so extreme on your cam choice.

If you're daily driving this thing, I'd go with agressive lobes, but some that had not quite so much duration. I suggest the Thunder Racing TRak cam. Check it out on TR's website.

Thunder Racing Custom "TRAK" Camshaft - 231/234 .640/.590 112 LSA 2400-6800 RPM Power Band. Excellent mid-range & high RPM power. 3200+ stall, 3.42+ gear, computer tuning required. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Comp 921 Valve Springs are highly recommended.

This cam seems like many others merely looking at .050" specs, but digging deeper you will see this is a reverse split cam when comparing .100" duration numbers. A lot of research and developement (and hours of dyno time) go into all of the TR cams, especially the TRex, TRak, and cheaTR cams. Very impressive grinds.

Or in simpleton's terms, this cam is between the 224 and TRex.

Good luck. My recommendation for the above cam is if you're using 1.75" tubes on a fat y-pipe running an electric cutout or with true duals dumped just before the axle.

Don't go too conservative on your converter choice. I'd look into which converter you want to run twice as long as what cam you want to run. I say run a 4000ish Yank. There are a lot of people who run these loose converters every day. Just put the biggest transmission cooler you can find in your car. OR! Use your air conditioning condenser as a transmission cooler. It HAS been done before.

If you are planning on going with that large of a cam, why not look into the small bore 225's? I was in the same boat as you with trying to decide on a set of heads that would match well with my cam. From what I have found out, the 225's are perfect for stock cubes and larger cams (mine is a 231/231, .598/.598, 112 lsa and will be bigger shortly into the future). Like stated before though, notching the pistons is most likely going to be a must so check with the vendor before making any final decisions.

 

.640" lift!!!!!!!!!!!!!!!!!!!!!!!

i'm not sure that will work with stock piston/valve clearances!!!

 

im either leaning with those 3 setups. the 2e and x1, afr and g5x1, or afr and you good ol 224. i dont want to go too damn huge. i think with either one of these setups ill be at my goal. im seeing 6 speeds with 2e and x1 putting down 430rhwp. so im wondering out of those which would suite me best for the street.

 

If you are worried about streetability, I would go with the TR 224 and the AFR 205's. Both will work well with one another and still have some street manners left as well as putting down some pretty decent numbers I would think. I know several people with the 224 to hit high 11's in the 1/4 with very little other than a good tune. Good luck with which ever setup you go with.

 

For a middle of the road approach, I'll recommend the same cam I'm running now, the TSP 231/237. I originally had a MTI T1 because it was one of the first cams out when I bought it and it had very nice street manors. I swapped out to the TSP came about 6 months ago. The lift on this cam is .598"/.595". One of the nice things about it though, is that it doesn't have aggressive lobes on it so it's much easier on springs. Granted, it will not wring every last drop of horsepower out because of that, but it's very streetable too. Mine drives just fine on the street.
