403+2x7665+417 intercooler+glide ford notch, cam swap mo-power 888whp 8.50s@157mph
this has been a long time coming for my friend Ryan who built this car
he sold a 5.3 80e turbo nova on air ride with plans to build a chassis and more race oriented car.
so sold the nova, bought a roller mustang already tubbed and partially caged
stripped it down and did more work to it, built a 403, bought a used holley intake with 417 intercooler, cut the nose off the car and did a tube front end etc.
built a twin 7665 turbo kit, running 4303 fuel pump, 80lb injectors, ms3 gold box, racepak iq3, 80e, single billet ptc converter.
overview video i posted showing off alot of the car
on the dyno today for shakedowns
motor literally only has dyno time on it haha
so we made 530whp today on 7psi, without the intercooler pump turned on
and 684 on 14psi with the intercooler on.
the only issue we had was we changed out the wastegate springs to get a lower pressure on the first half pull hit boost cut at half throttle LOL
its a fairly light, certified tubbed notch now so, it will fly, just gotta dial in the suspension and then we will throw ice in the tank and racegas in the fuel cell and see how far these little 300 dollar turbos will go

since the converter comes up and makes all its power sitting at 6200 waiting to generate the mph, it draws a bullshit chart
showing by mph shows how its continually putting power down over the mph range its accelerating over. much better representation of power curve on a large converter turbo car.

he has to send me the logs to confirm average boost, it goes to target then falls like 2-3 psi during the pass, presumably because of the small turbines
In your video you mention that the turbos were possibly running out of turbine or the compressor side was just making hot air at X boost.
What im wondering is how those twins could be done or inefficient on only a 400" engine?
My theory is.... lets say you add up the turbine side specs to make it one turbo. Probably wrong but humor me....
You are in effect running 400ci through a 1.92 AR housing (.96+.96) and a 130mm exducer (65mm+65mm) i know it sounds crazy but if that was one turbo everyone would say holy ****! Thats a huuuge exh side!
Or, another way of looking at it , 200ci through an On3 76/65
Are you able to log back pressure during pulls?
Am i soo far off for thinking this way?
This is just the **** i think of haha...

Wicked69 on here did awesome with the On3 70s that i believe had .68 AR exh housings.
He later switched to BW 366s and went even faster.
