- STi Top Mount Intercooler ('04-'07 STi)
- Full Race 1.5 Header w/ Up-pipe
- COBB Turbo Back Exhaust System (catless)
- AMR 750cc Injectors
- AMR Electronic Boost Control Solenoid (EBCS)
- NGK 1-Step Colder Plugs

- AMR BMI Cold Air System
- TGV Deletes Housings (Race Port & Match)
- Walbro 255 Fuel Pump

- Rom Raider tuned by AMR


Dyno Sheet:




Boost vs AFR:




Thoughts:

Very clean car. I noticed with the TGV Deletes and the Full Race Header the TD04 was a little on the laggy side. But not really noticable on the street. Really rips tires lose in 2nd gear. Customer was extremely satisfied. Timing was at 11.5 degrees at peak torque and 19 degrees at redline. Air Fuel Ratio was around 11.2-11.0. Tune was done on 93 octane.

This is the second plot i've seen a full-race header with a td04, and both looked quite laggy. My guess is it's just too much header for such a small turbo. Powerband looks good though for sure. 257 whp out of a td04 is nothing to sneeze at either!! Good job guys.

19* at redline? Don't you think that's a little on the low side?

Yes and No. We noticed on this vehicle giving it the timing up top did nothing. 1 or 2 hp. Why give it more timing if it is not worth the gain. We would rather keep is safe and happy.

On top of this, it is cold out. Gas stations are "winterizing" there gas. So again, safety and reliability is number one priority. Not the extra 2hp

That's odd... I ran more timing than that on my 2.0L wrx w/ a 20G, approx 5* more.

Could be that there was an issue with the engine. But..looks like it made great power!

do you have any other td04's with stock manifolds or an UEL or EL that you can lay over this plot?

td04 and FR headers.....i find that very weird. i was certain that absolutely no one under a 49 lb/min turbo would even think about that manifold....i take it a turbo upgrade is in the works, hence the 750cc injectors?

Phatron,


Yes. He will be upgrading the turbocharger during Christmas. He went ahead and did the TGV deletes and the upgraded injectors. I can print some plot of TD04 with stock manifolds off the dyno for comparison. There will be a big difference regarding spool time.

so the FR manifold isnt good on smaller turbos? i swear i saw some testing with Perrin EL's that showed that the perrins added power on everything from td04's up to gt35's. and i thought the fr was supposed to be better the the EL's everywhere.

i thought the 1.5 scroll design was supposed to aid spool and lowend power and was the whole purpose of the design to properly utilize the cylinder pulses?

It is a very nice header. Fabricated very well. On this vehicle with the additional TGV deletes and larger TMIC, it caused the TD04 to be a bit on the laggy side but as plus gave some great pull from low-mid-to-high rpm band.

Because all motors are not the same Some do more BTDC timing than others.

hey rob, do you have a dyno graph of another td04 2.0 ltr with the boost turned up on a stock pnp'd manifold or a perrin?

Extremely fun to drive.

He has an Aquamist Meth Kit that we are going to install. I am not sure if he would want to tune it on this or on his upgraded turbocharger.

Phatron,



Just the standard 1.00 setting the dyno comes with. We dont believe in correction factors. The vehicle makes what it makes, the gain is all we are interested in.

As soon as I get some time I will have to go through the computer on the dyno and find some to put on as comparisons.

on a dyno dynamics with 1.00 correction and my buddy who has a bone stock 2.0l bugeye dyno'd at mzm on there mustang put down 140whp as well. use the search button before asking questions. on a dyno jet, that read 15-20% higher, it puts down 180whp+ which is probably what you are used to seeing.

Agreed, adding a TMIC and TGV deletes adds more spool time then people realize. I have always heard that my plots look laggy for a td04 (only a few hundred rpm quicker then this one and I don't have the big header), but I have a Helix TMIC and TGV deletes.

Anyway, nice tune. That midrange looks wild. Also, about the spool, how hot was the header?

Yep, uncorrected DD's are killers for guys looking for numbers. Mine only put down 265whp uncorrected, but trapped 111-112 to put it into perspective.

It will be interesting to see what he nets with the bigger turbo on the FR header. Ported stocker works just fine for me. That's a hell of a lot of money to put in to a header on 2.0L car that could have been put in to a built block and netted more power.

So you're saying that this car would dyno over 300whp on a dynojet with a stock turbo?
