Stock internals - Trilogy Pulley size

[Dragcity]

The Trilogy kits came with a 3.4" Upper Pulley. The smaller pulleys are 3.2" and 3.0 ". I presently have a 3.2" on mine.

Question is, can our stock internals handle the 3.0 " pulley. Also, what size injectors are needed to feed that extra boost? Trilogy kit upgraded from 24# to 39#.

My fuel pump is already upgraded to a 320 LPH.

Just wondering what envelopes other Trilogy with stock internals are pushing.

[RubberCtyRauder]

injectors should be fine. I run a 2.8 on 39lb. i'm not stock internals

[Spectragod]

Go big or go home, or, in this case go small.....j/k. ;)

I wouldn't produce more than 10-11 pounds on a stock motor, if you car is a DTR, more boost won't help it anyhow.......lol.:D

[Dragcity]

Sweet, i'll pop on that 3.0 pulley for the next tune.

I am at 9.7 lb boost with the 3.2 pulley. As per the DYNO Run in 2010. How much more boost does a .2" drop in pulley size generate?

[Sully008]

I'm also on a 3.2" pulley, stock internals, stock fuel pump w/KB BoostAPump. I think we could get away with the 3.0", but would need to watch A/F closely while tuning. I have a 3.0 and 2.8 stashed away. I also have a set of 60lb injectors on standby as well as a Ford GT pump. And a Teksid block too.

The most I've heard of pushing the stock block/internals were members MI2QWK4U at 517rwhp, and I think mpearce was at 480rwhp.

I am seriously considering this:

MMR 5.0 STROKER 1000S Forged Shortblock (up to 1000 RWHP)
Starting at: $5,199.99
This STROKER shortblock adds .4 liters to your Mustang engine without anyone knowing, all factory parts bolt right on! Great for blowers, turbo or Nitrous. With no other changes this Stroker shortblock will add up to 40HP and 40ft lbs of torque! This shortblock can support up to 1000 Rear wheel horsepower!!

Why not put forge internals in the original block?

I'm only guessing it can't withstand 1000hp to the crank

But how much 800

I'm sure the results are somewhere in this forum

[RubberCtyRauder]

stock block alone has an unwritten number of 600 hp ive heard thru here

[Dragcity]

Yeah. the stock block will likely take about that, maybe a little less. I really like the new 302 boss block. Great technology and durability. Turnaround is much faster with a shortblock built and delivered. Swap a few parts and up and running.

[RubberCtyRauder]

the bottleneck is the blower. it has a choke point and the more boost the more heat. not many have exceeded 500 rwhp with the rotary 1.6 trilogy

[sailsmen]

It's the heat that you need to fear. Make sure you have the IAT2.

[justbob]

I'm curious why you only have 9.7? My 3.2 was pushing 11.7 and making 431/456 with nothing else but a JLT (air filter only), a lightning MAF, and a MAFia.

A killer chiller will be you friend....

I was making 472rwhp on a stock block, it did feel as though it was ready to grenade whenever I had been running it hard......racing prius's and civics.....

its on my list!

[Bigslim1]

I had put a 3.0 pulley on mine. It was running 11.5 pds of boost on the stock internals.

[Spectragod]

You could just buy a car with one installed? :confused::confused::confused:

[Dragcity]

Odd, yes 9.7 lb with a 3.2 but making 437 HP. I guess they all run a little different.

I have a jlt intake with 90 mm MAF. Yes, my kit is #224 and has IAT2. Kooks headers and x pipe with stock mufflers and tails. Also have the rear head cooling mod.

No kidding. The last pulley swap I was running on the Trilogy was a 2.8 w/4# lower on a cobra block cranking out 20.5 #s thru cams and LT's and only made 461.

I was literally melting plastic items under the hood instead of making any kind of power..

Instant boost however would be down playing it though. [emoji4] But she would heat up in seconds.

Stock internals, 112,000 miles at the time I added an Eaton... 13 PSi, now have 130,000 + on mine.... no issues so far.

That's depressing, sounds like a killer chiller and water to air intake cooler still won't be enough

[RubberCtyRauder]

killer chiller does the job..a few on here have it with iat less than ambient at times.

[mm svt]

Watching videos now, it's a must have

When we had the car on the dyno the tuner had it as high as 470rwhp, but backed it down to 443 to keep it from puking it's guts out, lol. The temp was 36ºc in the shop when it was sitting on the rollers that day. I've been pretty happy at the power level I'm at for the last 6 years, but there's always room for more.

[Dragcity]

Wow, 470 on a 3.2 pulley. Nice. I would love to get 455, now that it is possible.

There was a guy at the races with a Hellcat. Holy crap, those things are sick. 11.2 with 1.63 60 foot times. All he had was an air intake and M/T drag radials.

I want to get after those guys. Although, if they put $1,000 into them, they get to 900 HP easily.

[Dragcity]

I have gotten bit again.

[DEFYANT]

425/426 Hp/Tq since the car had around 5000 miles. Trilogy w/ 3.0. Miles now about 94K. Plenty of supporting mods, except the IAT relocation. No issues

I like Hellcats, they are tasty........ kind of sweet and salty.... :D :burn:

[Dragcity]

OMG that is too funny.
