I got the SI5 last year, good mid range, not all top end, it pulls hard up top & doesn't fall off.
Depends what you definition of daily drivable is. My tune is good, my car is an A4, I don't daily drive it, but when I drive it to work or whatever, the cam doesn't make driving it a pain at all. It is a little gassy at idle, all the positives far out weigh that though.

Here is my graph.

I'm running the factory heads. Reason being is because I am also going into a procharger setup, (d1 or f1, havent decided yet). I'm aiming for big numbers so I will not be using the same block. More then likely I will swap out my ls1 for a ls2 or 3.

in regards to if this cam will work with a procharger setup. Yes it will, its the CC of your heads that you need to watch for. NA heads are different then boost heads. I do feel there are better cams for boost applications, but the SI5 should work great. Its a great power cam from down low all the way through the curve to up top.

specs are:
SI5 - 231/237 589/595 112+4

The lope causes a very aggressive race car sound with the exhaust. Its a fast ramp cam too!

I didn't know we sent some pommy an SI5 cam? j/k :p

SI5 is designed for Stock internal LS1/LS2, Ibanez7 and Unstang have shown extra ordinary results

Cam only; typically this cam dynos from 380rwhp in an automatic 1998 Camaro/TA, 01/02 Fbody/C5/04GTO M6 pushes 400rwhp or 432 in Ibanez's case.

We installed SI5 in an 2005 GTO auto,423rwhp with usual bolt ons went 11.8x constantly and 10s on spray.

we also have an SI5V2 that uses aggressive lobes, need to run it in few more combinations.

another dynojet same settings and smoothign showed 432.

So far 1 car with it and didn't out-perform regular SI5 cam in a 346, then again some cars dyno 390rwhp and 425rwhp with same cam and drivetrain combination, so i'd like to get more real world numbers from it.

Had higher expectations, maybe in the next combination i'll see them?
