yup...thats as good as it gets right there...full tq from 3k rpm's and up

Big Ben

well still having some trouble at the switch over from vacuum to boost. I got the impression for the company that was doing all the work that they really don't care if they fix it or not. Seems like they just wanted my money. I am going to another shop tomorrow to get their feed back. The tuner at the shop is aem certified so that might help out alittle as well.

I'll keep you posted.

simplyscion

so the car just basically falls on its face during the transition? What does the wideband read? Is it running really rich? Pull the plugs and check them if you havent already

I am really surprised none of you supercharged TSXers are running methanol injection. A number of the supercharged TL guys did it and they saw decent gains. Typically on the Stage 1 kits, which are recommended for low boost applications, you will see a 10% gain. The kits are inexpensive ($250 shipped) and with the Stage 1 you just let it inject and let the ECU throw more timing in based on what it sees. So you don't have to custom tune it or always have it in the car. Of course you can get more hp with a custom tune but the ECU will make adjustments by itself.

Tsx536

You be fine when the ECU is in closed loop and using the Primary O2 sensor to keep the A/F ratio at 14.7. But, what about when the ECU is in Open loop? Isn't it running strickly off the fuel maps in the Comptech ACM module and ignoring the readings from the O2 sensor?

Tsx536

From what I've read, a good tuner can smoothin out this transition from vacuum to boost. I've also read that the M62 blower is known to have a little rougher of a transition from vacuum to boost.

As mention aboved, what is the A/F ratio when this happens?

ACCURATEin

...just got done reading all 7 pages of info.

Gotta say nice work bro! It always takes some balls to be the guinea pig when it comes to work like this, especially when over riding an ecu.

Impressive numbers, let me know when you're in Charlotte and we'll meet up.

Big Ben

Well....

I am out in Utah now on Vacation and decided to take my car in to put it back to stock. I told them to try one last thing before going back to stock..

Well I got a message from them yesterday and they told me it is running great and the new stats on it is 276 whp and 215 tq!!!! I will fill in the details when I get back from my trip and after I test drive it. The best thing is that it will only cost around $300 with parts and labor.

Wisc Badger

WHAT?????

simplyscion

I think he meant the cost on top of everything else that was already put in the car and paid for...he must have went with the water meth

Wisc Badger

i was gonna say...

i almost shit myself right at my dining room table.


GL you guys, hope I get to see one of these monsters sometime soon.

chuson

Nice~! That extra torque gain might fix your jerkiness drive?

Big Ben

nah didn't go with the meth kit. Also this is 300 plus the price of the sc kit lol...sorry.

Big Ben

There is no reason to wait until I get home....

We went back and put the stock injectors in. Took off the AEM FIC and put the ACM back on by itself. We crushed the fuel regulator alittle more (when installing the sc you have to crush the fuel regulator). We kept the 255 fuel pump on (not sure if it is nessesary to have)

Put it on the dyno and hit those numbers..

With that being said I will have some RC 650 injectors and a AEM FIC that were used for two weeks.

Seriously though, Great Job Ben. Looking forward to seeing 1/4 mile times, when the warmer weather comes...

As far as 'crushing the fuel regulator', do you think there is more tuning available with an adjustable FPR?

Big Ben

I am not sure that a FPR would allow that much more tuning. I think that it would help/make it easier in the tuning process but not something that will help that much, if that makes sense.

DAYTA

Wait, I'm confused...so what modifications did you keep on the S/C kit? Is it just the 3.2 pulley and a larger fuel pump? I can't believe you were able to gain 25wtq from that!!! How's your A/F curve looking? Please post the new dyno .

Big Ben

I will post the new dyno when I get back to atlanta. A/F are around 13. The pulley is a 3.0. The aftermarket fuel pump is still on and not sure if it is needed. I just didn't want them to charge me to take it off. They did more modification to the fuel pump regulator.

rmpage

What is your fuel pressure at now? I'd think that an adjustable FPR would be a good idea now that you're clearly well above stock levels, just to trim it back if desired.

Also, that AFR is a little high for that much boost through a blower...I'd want to keep it in the low 12s at WOT at most, just as a general rule, but if you're not running into knock retard then it might not be a worry for you.

Congrats on those numbers anyway; they're pretty impressive.

Big Ben

I may look into the adjustable FPR. I am not 100% sure about the A/F ratio because I haven't driven it yet. I am getting back to atlanta tuesday night so I should have more info on wednesday.

DAYTA

Again, this brings into question what a water/methanol injection kit could add. That would adjust your A/F ratio a bit to where you're running a little richer than 13.0, not to mention reducing the IAT noticeably since you're running higher boost (i.e. higher temps).

simplyscion

+1

Big Ben

Once I see how my a/f is going to run I will let ya'll know. How much richer could it run though with a water/methanol injection kit? From what I have read it would give me close to 300 whp. Front wheel drive ftl.

TommySalami

Which one was worse for FI cars, rich or lean?

simplyscion

It can richen you up into the high 11's low 12's range if enough is being sprayed...Short answer as far as forced induction goes, you generally wanna be running more on the rich side than lean.

jmathew34

any updates?

Big Ben

We ended up putting stock injectors back in it and crushed the fuel regulator alittle more to allow more fuel to flow. I to have a 255 Walbro fuel pump which I am not sure if that is needed. Everything seems to be running fine. A/F are at 11.7 and I am running 10-11 psi. I am looking into an adjustable fuel regualtor but it would have to be a custom setup since our FR is in the trunk.

DAYTA

Sounds great! Any driving impressions?

Also, just to confirm - the only mods you've done to your S/C are:

1) 3.0" HBP
2) larger fuel pump
3) crushed fuel regulators

If so, those are some amazing gains for not that much more $$$. 215wtq is EXACTLY where I'd like to be...

Big Ben

You will need to get a new belt and I also encourage an A/F gauge. The driving impressions are great so far. There has been a couple of times where it does the feels like its running out of gas/wigs out but I am thinking that it is because I go into full boost then back off. After I back off my RPM's are around 2k in 5th gear. It doesn't like that. And if it does that then I just let off the gas and it goes back to normal. That is why I would like to figure out an Adjustable FR. I am 99% there for it to be running perfect but that 1% is where it wiggs out. I have been driving my car now for over a week and it has only happend 2 times. Overall the drivablity is fine. I drive it everyday all day because I am in sales.

tsx 2 nv

this is GREAT news!!! way to take one for the team!

Tsx536

Wow...11 psi! You more than doubled what the kit was previously running. Hopefully you don't lose much power when you adjust the fuel ratio a bit.

How high are you reving? I think there is extra power up top in the power band, but our injectors run out of fuel up top with the stock setup. Maybe the fuel pump and and crushin the regulators help though.

Do you know what duty your injectors are running close to redline?
So you made no changes to the Comptech ACM?

Way to keep modding man

Tsx536

Also, Comptech has modified higher flow injectors for sale. I wonder if you could just run those.

Big Ben

Their modified injectors are 550cc. The took the stock injectors and modified them to plug in with no modification needed. There would be no way to controll them so you would be running rich.

rmpage

Anybody know what boost levels these K engines start to float valves at? I figure if you're running better than 10# in the manifold, especially up near the rev limit, the intake valve springs have a much heftier job to do than they do at baro. It might be a good idea to look into stiffer valve springs if you don't want to kiss a piston in the long term.

swift22

Valve float is cause by high RPM revs..not boost. Therefore unless he has custom cams or feels like revving to 9k all day he shouldnt need upgraded springs.

swift22

AFter looking at your dyno sheet if they can keep the fuel coming at higher rpms then it is possible if you upgraded your valvesprings to keep going!!! my gosh nice curves!

Also what about upgraded cams to extend the curve farther out..? Good work!

visuelz

So what's the new mpg with this setup?

rmpage

Boost will do it, too. He's easily got another 15+ lbs pushing on the backside of his intake valves as they're trying to close. How much this actually increases the risks of floating one, I have no idea, but the risk is certainly elevated to some extent.
