i will let you know. I have a 200 shot but that is track only, when I am on the street
I don't like to use the bottle.

btw anything has to be better than a hot cam

What do you think? 383 stroker - 175 shoot with good intake and exhaust systems.
Lobe Seperation =114 + 4
Valve overlap = 17.9
Intake Centerline 110 Duration 240.9 Lift .64533 Lobe area 31.8

Exhaust Centerline 118 Duration 245.4 Lift .63281 Lobe area 31.59

When the intake flows so much more than the exhaust, wouldn't you want the exhaust to carry more duration to make up for the exhaust sides inability to get rid of air as fast as the intake can pull it in?

I dont understand the concept of reverse split camshafts, GM certainly had the right idea with their stock camshafts, they make incredible low end, with a standard split camshaft. Stock cams are designed for that ultimate streetability, why do you think they don't use reverse split camshafts for that better useable torque?

GM designed it for smooth driving. Not neck-snapping torque. You've never heard all the talk about how LS1 cars have no ***** down low? Go drive an LT1 and then an LS1. Night and day.

If you overlay a stock LS1 v. LT1 the LS1 makes more power and tq everywhere.

Because of the shitty flow of stock exhaust. Reverse like 2 things, high compression and good exhaust flow. Compression based on DCR

well guys I am back from the dyno (car still at shop)
with the 234 230 602 598 116, it made 391 at the wheels with shorty headers and 2 1/4 pipe, the guy that is doing some of the work wanted before and after dynos (comparing headers because that will be the only real change) and after christmas I will have dyno numbers with long tubes and 3" pipe...btw its an A4, oh and I converted the dry nitrous set up to a wet and will have numbers too on the bottle

I love my reverse split except it will not cruise below 25mph. I have to keep working the clutch. But the idle sounds great, and it has good power. I have the stock heads, never been taken off, 78mm Fast manifold, P+P TB, AR 1-7/8 LT headers, deleted cat, corsa cat-back, mail order tune, 160 degree t-stat, and a couple more smaller parts, plugs, wires, etc. But it pulled 400 RWHP before the Long tubes when I had pacesetter mid-lengths, and 380 ft lb torque. I can't remember the RPM's the torque hit at I believe it was around 3500 but the 400HP hit at 6100 RPM with a nice smooth curve. I have the Speed Inc SI007 reverse split, I believe it's 228/222 .588/.588 112+3.

You just need more tuning to sort out the "under 25 mph cruising" issue.

i really want to go out and get that x1 cam but i plan on doing heads. but i hear if im doing heads and a fast 90/90 that im better off with a traditional split. but then i see reverse splits make sick power with heads and fast 90..what gives? and i do like the midrange the reverse splits produce than the traditional splits especially for a street car.

also predator-z, do u think the x1 will outperform v1 cam? the cam is 230/232 592/595 111lsa?

PREDATOR-Z

Combo combo, it all depends how you match the components. They are both 230 duration, so theoreticaly they should be able to put out similar outputs.

I have the TR230/224 and it has great street manners. Makes great power from any RPM (4400 stall might help that!!) and has awesome top end. Very impressive for a big-stalled A4. 1st time out at the track I ran 11.93 at 113. There's room for improvement, but I'm thrilled with the setup.

i havent heard of anything negative bout reverse splits!! everyone that has ran the reverse split whether its the tr 230/224 or x1 all have been happy with it.

my x1 put down 394rwhp 386rwtq thru an m6 with 12 bolt and 4:10s. it still doesnt run worth a crap, the tsp dyno tune wasnt all that i expected.

I am running a 228/222 reverse split cam and have been very happy with it. Great drivibility and power. It made 393rwhp with the stock 3.23's and a 3600 stall.

My specs are below, running a reverse split with fast 90/90 and ported heads. from what everyone is saying, perhaps I should try a different cam, my times are in the signature

iTrader: (5)

those are really stout numbers!! thats what ive been trying to figure out, alot of people say if u do fast 90/90 and eventually heads go with the traditional split.. but guys are making just as good as numbers if not better with fast 90/90 and heads with reverse splits.

alright car made 405rwhp n/a

What does the +4 mean? What would you guys recommend for a good daily driver with just bolt-ons
