Default Any 400 rwhp 228/228 cars?

I was thinking of getting this cam installed in my c5 corvette A4. i have long tubes,CAI,exhaust, and 3000 stall. Im also debating if i should get it on a 112lsa or 114lsa. Im looking to get close to 400 rwhp with a good tune. What do you guys think.

I put down 405/390, w/ a conservative MTI tune, and Stage IIe heads.

Great cam! I have a 228/228 .588/.588 comp XER 114 LSA +4...Love it. The car made 410rwhp cam only through the exhaust and I just installed PRC LS6 heads same cam. 432rwhp 400rwtq untuned...I expect to make 445 to 450 tuned through the ls6 intake.

I have the exact cam but I didnt make nearly that much HP. Having a stall robbed alot of my HP but if I had a stick I would deffinatly have around 400.

A little bigger 230/227 gave me 427rwhp and 386rwtq in an A4.

you won't get anything near 400 rwhp with a 228 cam in an ls1 a4 vette.

you have the automatic and irs working against your dyno numbers.

i don't know of many cams that will put an ls1 a4 into the 400 rwhp cam only. i think the t-rex and g5x4 are the only ones close, and more often than not...won't do that in a cam-only car.

even if i have all the boltons and a good tune? I see lots of A4 Camaro and T/A guys having 400 rwhp and have cams alot samller then G5x3 or Ms3 etc....

well fbodies have a solid axel vs the vette with IRS that is why vettes dyno lower, I still think you should go with the f 13 on a 114.

I would go with that cam but im worried about not having the lowend, and i still have the 2:73 gears that i won't have the funds to replace untill the end of summer. also thunder racing has the cam pkg with everyrything you need for around $700.

you do? where? also, i'm sure they are running a 90/90 setup...which is almost the only way you will achieve 400 rwhp through an unlocked converter and cam only.

Sorry dude I dont see it happening either. Your 3000 stall and IRS are gona rob some power. I however do see it being possible with a 90/90 setup and some good heads. Anyways Dyno #s arent mprotant its what you do in the 1/4 mile.

Im not looking to break any dyno records or anything like that, i just wanted some opinions on what you guys thought. thanks for all the input guys. what i'm mainly looking for is a car thats a daily driver that can hold it's own. if it takes some pp heads than i guess ill have to go that route.

I know someone in town who got @ 405 with a 228 and stock heads, tuned at CAM in Durham, N.C. But he has an M6. You will not get that with an A4. Not that it matters except for bragging rights. IMO a 228/228 is one of the best street cams out there for stock cubes.

Not quite the same but I have a 226/226 setup that makes 414/396. This is on a Z06 though, so LS6 heads and LS6 intake, stock TB, UD pulley, longtubes, x-pipe, tune, heavy motorsport Z06 wheels.

Hope this helps a little anyway....

that cam 228 cam with a nice 3600 stall would make a killer street car. that vette is lighter than most f-bodies, so you might have comparable track times to larger cams in an f-bod...

but you won't see 400 rwhp with that cam alone in your stockish c5...

with heads, yes you'd definitely be close. i also think you'd be close with a 90/90 setup...

intake+tb vs heads? i think heads are cheaper and would give you better gains from idle to redline..over the intake. (dayum those 90/90 setups are salty)

Going to be hard without heads and having an A4. Before my ported TB and Cut out I made 388/375. I bet I am pretty close to 400, but wish I had some heads now. You may not hit 400, but it will be fast and still drive pretty decent.

Thats a myth. From what Ive seen vettes with an M6 usually dyno the same or even HIGHER than an F-bod. The IRS is a wash. It doesnt make any difference on the dyno. Your right about an auto however, even locked on the dyno it will suck up about 5% more horsepower. That being said 400rwhp is certainly possible on an A4 with this cam and a good tune. Not to mention you will make more overall power than overcamming the car for peak numbers.
