Okay, I had an stock n/a ITR, one JRSC ITR with 190whp and now I drive my turbo ITR.

Most people here know my setup and I think I can honestly compare those 3 setup.

Peoples who are talking about turbolag are false. Okay in AutoX it is a benefit to have a n/a or roots stlye SC. But on daily street driving turbo has the best powerband!!!!!!! I make above 3500rpm more power with turbo than with n/a or JRSC. I have compared my 3 dynoplots from those 3 setup. On 5000rpm a n/a stock ITR is making only 110whp.

Donīt let this thread bekame into a turbo vs n/a vs SC debatte. I only whant to share my experiences with those setups.

Turbo boost oWnZ.

 

Nice job Christian.

Now about those wings.

 

.....please post up the dyno plots together so we can compare too!

dynoplot from my stock ITR. On the lft side this is the Kilowatt rating.




dynoplot from best JRSC dyno with 5.5 psi



On both dynoplot these are brutto kilowatts. You must multiplikate it with 1.36, then you get horsepower. Newtonmeter into Tourqe is multiplikate with 0,75

just because a turbo car may make a lot of power at a low rpm does NOT eman it is lag free. the term is usually applied to what happens if one is driving steady state and then steps on the gas. regardless of the RPM you are at, a turbo will require significant amounts of time to spool from steady state to WOT or high load. blown cars do not have this tendancy. do not confuse the term lag with 'lack of low end power'. they are truly distinct.

 

So you dredged up this post for your own little schpeel?
That's simply the price to pay for loads of additional power.

 

I'm never below 4000 rpm in autoX. It's called downshifting and using your clutch

 

Zyg: not really, but i was searching the archive for info on JRSc ITR's and came across this one.


tommy: guess you just didn't understand what i meant about lag. it's not rpm dependant, but load and spool dependant. 3000, 4000, 8000 rpm, lag is lag if the turbo isn't spooled up.
