Im looking into getting a turbo kit from Inline Pro, my only problem is that i hate turbo lag. I was wondering if you guys that had turbo setups on your cars could tell me how bad the turbo lag is. More specificaly those with a T3/T4 turbo or the Inline Pro turbo kit.

I know that so far no cam has really produced any gains NA. I was wondering though if a turbo cam has produced any gains on a FI engine. Im talking about streetable cams not racing applications.

There is pretty much no turbo lag with most turbos now-a-days assuming your in their spool range.

My GT35R turbo starts spooling at 4k and is fully spooled by 4.8k. To spool takes less then a second during that range and when I'm above 4.8k and I go from 0% throttle to 100% throttle the lag time is negligable (less then a second).

With the smaller turbos (30 series) they will spool even soon (3-3.5k) and again in the powerband its near instantanious spool time.


As far as cams go, don't waste your money. None have proven to gain power. The honda engineers were definatly on their game when designing the stock cams.

My turbo starts to spool at 3300 RPM. That is it make positive boost there. Full spool is somewhere in the upper 4,000 range. And thats with a restrictive exhaust putting a damper on everything.

I have yet to see a set of mainstream cams that have made any significant gains on a daily driver FI S2000.

If you are trying to zip around below 3,000 RPM, you won't have much go. But who drives down there anyways? This engine is happiest in that 3,000-4,000 rpm range for daily driving. Coincidentally, thats the same time my
powerband" kicks in. Like a freight train.

My car makes 200 lb.ft of torque at the wheels at 4,000 RPM. 260 lb.ft @ 5,000 RPM. 293 lb.ft @ 6,000 RPM.

Turbo lag? Would you rather wait for 125 foot poounds at 7,200 RPM in a stock car?

if your engine is stock and boost at around 8 or 9 lbs you wont feel much lag. If you go low compression there are some lag.

ya@inlinepro

slimjim's setup is on a lowercompression setup. picking the right turbo is what you need.

again, slimjim's setup spools at 3300rpms. IT SPOOLS very very fast...

edit:

sorry i got off topic. But there aren't any cams that are good right now for the FI setups.

i'm low compression and i dn't have much lag at all with the inline pro kit

i'm running the sc61 and it spools fully at about hmmmmmmm, i actually don't know off hand, i'll be right back lol

ok after my little test, i couldn't really tell exact full spool because the as$ end was all over the place but it was somewhere near 4-5grand

thanks for responding, I havent been in the turbo scene for very long. How much of a difference going to a ball bearing turbo would make. I have an idea of the T rating for turbos but i dont really know much about the series rating system.

I believe if I recall correctly, I'm fully spooled at 5,000
Let's not forget the boost that you get before full spopol, that will be a lot more than a S/C will ever get
