I am odd lol. I just tell it as I see it which is based on what the data says.

Nah wiggums 0.7 cover actually spooled better than my 0.5 cover with the 66mm wheel. The shape of the curves were identical.

We both have modified cam tables, and both of us have played with cam timing a fair bit and shared info. Playing with the tune will never recover the lost spool on my car. If I went out and got a twin scroll / twin gate manifold then it would e a different story! XYZ's (think it was him) car is a good example, his big GT42 on a good manifold out spooled his GT3566r on the stock manifold....going by his dyno sheets.

I have an external gate and wiggum has an internal..both same turbine AR. He still out spools me.

He uses HP though which is missing a cam max retard limit table which is TP based.

So you sayin with identical compressor and turbine wheels Lukes spools faster with the .7 housing over your .5?

I said it in another thread that I think my .7 on my fg spools quicker then my bf with .5 but that could have more to do with the fg flowing better ect...

My old turbo had this setup, made 434rwkw at 19psi on 100 octane, was an impressive setup :-)

Difference between the 0.5 and 0.7 cover with a 66mm wheel was buggerall...though the 0.7 had a bit on the 0.5 which I was quite surprised about. It is what it is!

I really need to run mine up again since changing the exhaust and see if this puts the .66mm .07 over the 66mm .05 down low

Dooo eeet!! I just want the smallest turbo that will crack 400rwkw on pump, then do a bullsh*t tune on sucrogen for powercruise!!

wouldn't the smallest that will crack 400 on pump be the stock one?

wouldn't the smallest that will crack 400 on pump be the stock one?

Depends on how high the dyno reads, Autotechs dyno has never seen 400 with a stock 3540 on 98.

Also depends on the trans, mine is on e85 , 4 speed and convertor.

Well I've decided to go the same turbo as veva. With the billet 61 mm wheel and .7 a/r. Dave reckons he hasn't tuned a turbo like this before so hes not sure how it will go but I'm hoping it peforms as vevas did and then ill be a happy man....lol
