99 1.8 - TD04 MS2
#1
99 1.8 - Subaru TD04- High 12s 1/4 mile pass
Been meaning to post this for a while now, numbers are flywheel
99 1.8 NB
Stock long block
2.5" Downpipe, stock cat and center to 2.5" Cobalt silencer
Subaru TD04-13T
650cc EV14s
MS2 Enhanced by MSLabs
20% Methanol premix in the fuel tank
Self tuned
Boost target is 12psi up to 5000rpm then tapers upto 15psi by 6000rpm
Best 1/4 Mile last year was a 13.41 @ 106mph, no idea on the power but an educated guess on 210-220flywheel based on the 10.5psi boost target that day

Help me understand what I'm seeing here and it n your other thread.
You are running:
standard TD04L-13T
99RON which is roughly equivalent to US 94 Octane fuel
Making nearly 300 WHP
Stock Bottom End
99 head with VICS
9.5:1 compression ratio
Please correct any errors above.
EDIT: What was outside or MAT temps, and are the results uncorrected?

Ambient temps of 16c, MAT 35c. I can't remember uncorrected figures but correct were to DIN standard.
I'm as surprised by the power its making as much as you are, I can only attribute that down to Tyr use of methanol (as close as I can get to E85 here)
I'd call it flywheel power but the base line of 278bhp with a, 111 trap speed is in line with what you would call whp

Not disagreeing with you 18psi.
I've already studied the compressor map enough to know 275whp should be the absolute most they'll do, hence my thread asking about 19T hybrids.
Methanol does carry an additional oxygen molecule and that does make up 20% of my fuel
The original 279whp figure ties in with my 1/4 mile trap speed, I'm back at the drag strip on Saturday to we will see what happens to trap speeds. 113mph should be expecting at 300whp

Exactly. I think 250 WHP is all this Turbo should be able to produce, regardless of pressure ratio. Or 270-280 bHp. That's why I was thinking possibly a cold day and I corrected numbers.
My understanding is that the oxygen in the methanol is not available for combustion with the gasoline. It's not like NOS.
It would appear that you do a great job in the quarter mile.
Pics of build? I don't find a build thread.

I've got two events at the drag strip this month then that's it for the rest of the year, once those are done I'm going to head back to the dyno and play around with boost targets to bring the torque back to a sensible 210-220ft/lbs until I fit a set of runs and run allofit
In for trapping 113 and showing the world a tiny little TD04 can do 300whp though

Not sure where you are getting your HP to trap speed numbers.
A quick search turned up this: Speed vs HP
Which yields this:
Which makes more sense to me. And I think this is a rough attempt at bhp.
EDIT: But the car is fun, yes?

Using this calculator
0-60, 0-100 & 1/4 Mile Calculator :: TorqueStats Modified
Car weighs 1120kg with me sat in it.
The car is immensely fun, and as we all know dyno figures can be debated until we are all blue in the face. Its bad enough comparing dyno numbers from different dynos in the same country let alone on different continents

lol 113 would be nuts. I'd love to see that.
buddy of mine was trapping 118 on a stock long block BP for at least a few track trips before it finally exploded, so I know it's possible on stock rods as long as you do it just right, but I don't think I've ever seen a td04-13t trap 113 before. that's gotta be some sort of record if you pull that off
