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

superhog88

you said he has a 4-port controling the wastegates does it control both or is there another 4-port on the othe side and are you using a c02 system to control it

Love your build threads.
1 request - can you put rpm into the dyno graphs instead of mph?

denmah

one 4 port, using manifold pressure, split out of noid to both gates

i can but with a stalled auto they look like **** and make no sense


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.

denmah

looking at rpm you might think what a crappy power band
reality is, the car put down 600 tire the entire time over a 50mph change.

Is the intake a midrise intake. What are your thoughts on the intercooler. I am thinking of the same intake combo.

denmah

iTrader: (2)

it is a mid rise i believe, i really like the intercooler so far seems to work great, i cant wait to turn it up!

superhog88

could you draw a schematic of how its wired and plumbed and where did he get the 4-port controler

My car did the same thing on a dynojet. RPM graph looks super weird. Mph graph looks smooth.

had trouble immediately with his 80e and decided to go glide








8psi


12 i think..


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

denmah

iTrader: (2)

its because the converter comes up, loads up and moves around sometimes, draws **** lines all over on a RPM plot, mph makes more sense to look at to check efficiency

denmah

iTrader: (2)

its plumbed like normal just splitting out of the feeds to both gates

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...

denmah

they quit at 700 tire on my friends 365 cube build also
i also would think they could go farther but doesn't seem like it. since 2x in a row have done it

Is it possible the exh side AR is too big (.96 on those) not creating enough drive pressure? Only 200ci spinning an 76/65

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.

Any updates on this car sense the switch to a powerglide

Sick build. I have a love and hate relationship with seeing these type of builds. I love them for obvious reasons, but hate them at the same time when I look in my wallet.

The 65 turbine won't be an issue in that manner. I run a 65 on a 231 and it spools and drives fine.

Bad *** build!

had it out at the track and in three passes broke the stator in the converter

he had his trans place go through the trans and they said they would fix the converter also

they fixed the converter and he was out again yesterday making shakedowns
