Re: Stoke engine 4.0L turbo GT40
That is impressive!! What was the boost? What displacement?

Re: Stoke engine 4.0L turbo GT40
I don't want to cast doubt but, Stock 4.0L puts out 190HP at the crank, 150-160 rear wheel. 8 pounds boost on a well optimized system with headers, intake, TB, ported head, cam, intercooler will put out 50% increase in HP. That's a well known proven fact. Either the engine is putting out more 'stock' HP, there is more than 8 pounds boost- more like 16-18 pounds or the Dyno is 'very generous' in it's power numbers. What did you use for injectors? What controller? What were your A/F ratios like?
It does sound great reving out.

At 5.5 PSI of boost I got 275 RWHP 300+TQ and 8 PSI of boost also I got 332 RWHP with 100% meth.
I can't going over 8 PSI because I don't have forged piston and rod also intercooler.
How can I going to 16-18 PSI without these thinks????????
who made my project name (Shorco) in this forum, his project name GT4202 and have I a look for this link:

The injectors size 36lb, DFI control unit, and A/F ratios 11.6

Re: Stoke engine 4.0L turbo GT40
Nice numbers.
Next time you are on the dyno, take off the tubing from the throttle body, effectively taking the turbo out of the loop, and do a Naturally Aspirated only (no turbo) dyno pull for comparison.

Wouldn't be full NA. More like NA with a very restricted exhaust.CobraMarty wrote:Next time you are on the dyno, take off the tubing from the throttle body, effectively taking the turbo out of the loop, and do a Naturally Aspirated only (no turbo) dyno pull for comparison.

Re: Stoke engine 4.0L turbo GT40
Done before, surprisingly very little difference. With the compressor not compressing, the turbine spins and flows quite well.

i'm not sure if this wont overspin the turbo and can cause damage maybe i'm wrong but the better way would be to open the wastgate fully open to bypass the turbine completely
