I was just curious how my 1969 Chevelle with 6.0 and Twin ON3 70's stacked up. I have gone 5.99. Has anyone gone or knows if anyone has gone faster using the chinese turbos?

1/8th Mile.

subscribed but I only went 130 before the cam and with way to low of a stall.

Wicked69

130 in the 1/8th?

How much boost you run that 5.99? Fixing to post my build with on3 twin 70's

Wicked69

22lbs

Wicked69

Anymore boost and the et wouldn't improve. Tried as much as 25lbs

Backpressure? Running those 70's on my 4.8 maybe I can get a little more out of those 65mm turbines

Wicked69

I would think 70's would be too big on a 4.8.

Well 65mm turbine is pretty small. I wanted the 67's but all I saw was ball bearing and I was not gonna pay 700 for on3 turbos

Wicked69

I agee. I wouldn't $700 either.

Do you mean cheap Chinese turbos? Precision turbo's are made in china.

Wicked69

Yes I was referring to what everyone calls "junk" lol. Gt's, CRX, ON3, etc.. I did not know precisions were made in china. Are u sure?

i am not on the super fast spectrum but i have built a ton of fairly fast cars with china junkers

Wicked69

I chose the chinese stuff because of u. Lol. I figured I would never be the fastest because I am too poor and car weighs too much. I was hoping to claim the title of fastest something....lol

Your stuff rocks. I learned a ton from yout trials.

Im currently doing cxracing 80mm on my 4.8. going for high 8's.

Wicked69

I hit just shy of 117mph. I lose it all on the shift. My convertor drops 2 grand on the shift. I hope to pick up a couple tenths when I send it back in.

There are several limiting factors that are a part of this, not that they just will not do more and or make more power.

Back pressure
Seat pressures
Convertor
ETC.....

Convertors are sometimes a tricky area esp if there built and then Engine rpm spec changes and or gear swaps happens or Taller or shorter tire is added, this all plays a role.

A 17 blade to a 15 blade will yield around 200 rpm per blade drop, shifting the car in your case 6400-6600 will yield around 1000-1200 drop.

This in turn will may be a cause of more boost needed and or slight timing if safe due to the tighter lock up.
