I will eventually but I am traveling west the rest of the month and won't be driving my car. I also need to flash in some revised maps once Junior sends them to me. It's over boosting a bit in 4th-6th gears on both maps, so I need to take it easy until we dial that in!

I can tell you this, it spools almost as fast as the VF without the boost/ torque spike and I'll bet almost all of the VF power curve will fit inside of this build's! Driving it is very civil on 93 and I saw 25 mpg at 80ish mph on a recent road trip I took with it. I love my high compression motor! Driving it on E85 is another story, the frickin car is very hyper on E85 and wants to go hard all the time. It's almost hard to modulate the gas pedal. I told Junior that driving it on E85, I feel like it's looking for a fight all the time

No offense but I disagree with your earlier post about the Kelford 264's not being big enough, It's not the cams holding worksti's build back nor the tune. I'm not sure why that build fall off towards red-line. I'm running the 8 cm HS and that's not holding me back at all with the MVR EWG! It's the sum total of the parts build and maybe the gas!

nice.

yeah we'll have to disagree. 264s are something I would use south of 400 and under 7k. going past that you need more duration. 276 would be ideal. although I suppose it depends a lot on the range of avcs adjustment and how far you can lean the cams over from side to side.

Thanks, yeah the AVCS helps and the Kelfords are true 264's unlike some others. Some wanted me to go with the 272's and they would have been great I'm sure. I may give up a little on the top but gain it down low and in the middle.

I'm happy with how flat my torque curve is. I do love this 3.5XTR which is pretty close to the GTX3776, it has a 64mm turbine wheel vs. the 68mm wheel of the 3576. It's very responsive on my car especially with the high compression, the KB header and the my trick exhaust!

Thanks man! Yeah Junior's eyes were open on the results we got, it's the whole package the Dom 3.5XTR and all but the KBHH really contributed to the characteristics of the power curve! Who do you think is supplying/ making Junior's forward facing set up on his carbon car! That biatch will spool up wicked fast, reducing the piping even more and it will be an easy adaptation! Check out the Killer B results thread if you haven't already!

I really like this Dom 3.5XTR a lot!! I like the wheel pairing it really helps to flow more air and spin up the compressor fast!

Junior liked my build even with the injector issues I had. He road tested it and I came out to talk with him, he shut her off and handed me the keys and said......good luck I said well I know it's not making what your XTI's making in power and his exact words were, "na dude....this things ****ing fast!!"

I'm only making
415/405 on my dom 3 and it scares me. I can't even imagine ur setup. They really seem to come alive after 23psi. At 22-23 I wasn't making crap, put my meth to work and raised the boost to 27 and it was like night and day.

Mike Malin told me the 3.5 and 3's peak efficiency is 24 psi and up. On 93 Junior set peak boost at 21 psi, as I have high compression at 9.5/1. I have seen 24-25 psi in 4-6th on the pump gas map. My car feels very strong even with the lower 21-22 psi pump map! It's definitely a beast on E85. A buddy of mine over in Detroit who has 3 STI's and a very fast 2006 said to me last Saturday....you're gonna really piss some people off with your XTI

Do you have an E85 map?

Nah I wish. It's not to readily available here in south jersey. There's 2 pumps and the closest is a 40 minute drive so I use meth to get my boost and afr up safely. I'd much rather prefer e85 though. I can't believe u made 100/100 more with e85 that's just awesome. 415/405 is nice but 515/505 on e would be a dream come true for me. That power in my sti is somewhat expected though, u In ur xti is gonna be pissing kids off. Lol. That's so awesome

Manitou I just noticed you made 450 with a tmic and 22psi on that 3.5. Thats pretty impressive imo....cant wait to see what it does in lower gears

Thanks Slim! Yea, I think that with the injectors sorted out now it will be closer to 550 WHP and 490 WTQ on E85. I made 440 WHP and 380 WTQ on 93 pump! I think it will definitely piss some kids off but it will also piss off some so called super car owners as well! I really don't go looking for it but if some JA screws with me, well it might not bode well for him!

I did not build this as a drag car but I can't wait to see what it does in the 1320 this spring! I don't know it might be capable of 10's We'll see!

Thanks Kurt, my build has worked out well! I like running a tmic to keep the intake tract short and the ETS is a good intercooler. Junior liked it but originally I had the IAT on the turbo side of the TB and the temps spiked to 175-180 during 4th gear pulls on the dyno and it pulled some timing. In 3rd gear it wasn't an issue because the pulls are so much shorter in duration of time. It really did not happen on the street either because of the air flow over the IC. I moved the IAT to the under side of the tmic right in front of the TB so now its working very well. I may wrap it in a reflective insulation sleeve so it does not heat soak during stop and go. The ETS tmic is very efficient and as soon as air moves over it it cools down quickly!

I did notice that on 3rd gear pulls it was flowing 440 g/s at 7K+ rpm's thru the intake and that's approaching the peak flow of the turbo.

The motor assembly just before install.

My sleeper XTI after a bath!

My plan for it this winter is to install a dual HID Morimoto kit and black out the surrounds in the head lamp assembly! I also plan to black out the tail light surrounds and install LED lamps.

yeah that car is going to piss off some folks....

I also like that you went with a higher compression. the 9.5:1 seems to be working well for you and Im sure makes the car feel snappier off and going into boost.

Yeah, I love the high compression motor! Great off boost response, spool and it gets great gas mileage!! The D25 heads are nice and with the PnP/ big valves and bowl work, they flow very well!

Most folks have no idea what it is, I'm sure it's like wtf just happened? That was a Forester right? It's pretty funny really! :LOL:

Its an interesting thought of comparison what would be if higher value. The d25 combustion chamber or dual avcs of the sti head

I think I would take the D25 heads better and smaller bowl shape. More hemispherical and I think it's 50cc compared to the B25's 56cc. I can't remember are they doing the DAVCS on the D25's also or is it just the B25's? DAVCS D25's would be the ****!!

I dont think there are d25 davcs heads. How difficult would it be to deacivate exhaust avcs in the ecu to run d25 heads on a sti motor?

That's a good question, can't be that hard to do right. Mechanically it's not that big of a deal to convert. Ron, Dom, Junior (if you see this) what do you guys say?

as far as the ecu goes it would take 2 seconds to 0 out the exhaust tables. or you could just unplug the solenoid in the engine bay.

but i dont think there are davcs d25 heads....so you wouldnt have to do anything to the ecu.....the solenoids wouldnt have anything to hook into. You wouldnt be running an exhaust avcs cam sprocket on a non e-avcs head....the oiling passages wouldnt be there to allow it to work.

dont take anything i say as gospel though. im no motor builder.

which head do you prefer? is there enough of a difference to justify a switch? What value do you attribute to DAVCS?

there are gains to be had with e-avcs....is it worth a swap...i dont think so.

There isnt a reason to swap a non-e-avcs head into an e-avcs capable car.....and you cant swap a e-avcs head into a non-e-avcs car because there wouldnt be tables in the rom to control it with the stock ecu.

its pretty hard to make comparisons of the heads across platforms...with the 08+ dual avcs, the car weights are diff, the tires are bigger...trying to compare to a wrx with diff gearing. And its very rare (at least for me) to get cars across all 3 platforms (single avcs sti, dual avcs sti, single avcs wrx) that have the exact same setup.

Yes there is a reason to swap a non e AVCS head into an e AVCS capable car! It's not so much about the e AVCS, AVCS, non AVCS it's about the combustion chamber and volume of the CC. It would be worth swapping a D25 head into an 08+ STI to get the better shape of the CC and the lower volume!

It sounds like shutting off the e AVCS solenoids is not a problem so I would say its worth it if you wanted the higher compression and more efficient CC! JMHO

Its Interesting. Comparing most newer stage 2 stis to wrxs, the wrx's hold power better up top almost categorically but there are other differences. I would think having acvs on the exhaust cam would pay bigger dividends long term. Ill be interested to hear from other tuners.
