what kind of power are you guys putting down with your forced induction 18's and 19's?

[pro 5.0]

According to my math at 18 psi the Hellion car should have made 1069 rwhp, at 9 psi you should be about 824 rwhp. When you ran at the track was that just off the foot brake with a 2 step leaving in 2nd gear ?

The Midnight car is not a real world scenario as it has a liquid to air intercooler, lighter brakes and K member etc, a normal person isn't going to go that far. It's fair to say that any 18 and up with the 10R80 and 10 - 12 psi from a TT will fall out of a tree and run a 9.50.

Yeah with a mid 1.4 60'

Liquid to air doesn't do anything power wise if they're on E85. Only adds weight. With all of their lightweight additions they claimed 3800 race weight and then the driver of 200lbs

I haven't turned mine up at the track. Mine made over 900 but only ran it at 9lbs at the track

Mid 1.40 60 ft is more than enough to make it happen, once you turn up the boost that mph should start creeping up to 155 plus that's when you will get where you want to go.

Yup thats where I want to be! Hoping to hit 8's. Should be good weather for us next weekend as well

8's would be cool good luck.

Ok but the OP specifically mentioned posts about popped motors. I have only seen one.

Do you have any details on the 2018 failures? Power levels? Fuel? What broke?

The 2 I know about are a 2018 Whipple car with a fuel system on E85 making 975Hp, and the other was a turbo car on C85 making 1000HP with a return fuel system that made the power 1 time on the dyno and let loose.

Is the Whipple car the one that Signature Speed put together it let go ?

The Honey Badger car made over 1000 on a Mustang Dyno, which is close to 1070 on a Dynojet, personally I think the limit should be 900 rwhp on stock parts and it should last.

Thanks for the info. The turbo car was a wrist pin or pin boss in the piston, no? What broke on the e85 whipple car?

Im putting a twin turbo kit onto my 2018 mustang but ive been seeing a few posts now that these motors aren't holding up as well as the 15-17 coyotes. Is this true? my 2017 is making over 900 on the stock motor for over a year. now im getting worried with the posts of pistons breaking on the gen 3's

So far we’re up to 2 known failures on FI 2018’s. One was maybe a piston. Where are the others you mention? Is this a sufficient data set to comclude the 2018’s aren’t holding up as well?

Hey Mike

Ive been seeing the posts in the different facebook groups not on this forum. I had also spoken to some tuners that said they recommend building the shortblock because there is a problem with the pistons in the 18/19 cars where the pins break out of the pistons. Ofcourse I haven't experienced it for myself as my kit is being made and installed on the car now.

 

[engineermike]

Here are pictures of the gen2 and gen3 wrist pin bosses for comparison.

I recognize that lower picture from the MMR teardown, in order to make a true comparison both pistons would need the pins removed and the surrounding area would need to be measured. They would also need to be placed at the same angle for a fair visual comparison.

Yellow badger is only one I know of.

I know of several failures. Almost every brand kit, both turbo and supercharger. Boost and power levels vary with each failure. No real correlation for the failures but it seems the best theory so far is the stock block may have QC issues and cylinders have been found to be out of round. There is also the discussion surrounding the wrist pins.

That being said, my car made 1024whp/829ft-lbs on 12.4lbs of boost. Made over 850whp for all of HRDW on roughly 8.5lbs of boost. A handful of pulls done at 10lbs made around 950whp. Armageddon Twin Turbo car.

Torque plays a big factor as well, once you go over 750 on stock parts it's just a matter of time. You have to limit the timing to about 18 deg even on E85, how much timing was in your motor 21 deg ?
