e40 Tune, Low HP???

[westcoaST]

I'm at stage 3 and have been working with Randy on getting am e40 protune. We're getting 286 ft-lbs of torque, but only 210 hp. I'm using V-Dyno, I don't know what he's using to calculate HP. No matter what we do, we can't get above between 205 and 210. Heres what I have installed.

Levels IC
2J Racing catted downpipe
Mountune air box and Mountune intake
Mountune charge pipes
FSWERKS exhaust

Randy wants me to pull the downpipe and install the OEM one. Obviously, I really do not want to do this, but I will do it if the consensus is to do it. I really think at less than 20,000 miles, its pretty hard to imagine that the cat is clogged. Especially since the DP only has about 10K miles on it. Does anyone know who's cat the 2J racing DP uses?

What kind of HP numbers are others at stage 3 with a 2J racing downpipe getting? On e40 of course. I used all the parameters listed on the V-Dyno sticky. I'm getting about 187 hp on pump gas and a cobb stage 3 tune. Even 100 octane only got 205 HP. Any help would be appreciated.

Thanks

When I was on the corn wit E30 and his magic I was seeing around those numbers and I had the 2j catless with about the same set up as you. I think its your headlights .. We should swap and see lol

 

[westcoaST]

HA. those are a lot easier to swap than the DP. Thanks for the input. I think 205-210 is pretty OK, especially with the big torque I'm making.

I noticed if I kept ESC on, my HP numbers were lower.

For me...I'm running E30 with the mods in my signature (with the exception of the intake as I was running the mountune setup at that time) and the Vdyno results are in my signature as well. That was done with the air being 20-30 degrees cooler than now. The vdyno really, for me, fluctuates a lot based on the weather and temp outside.

I say go straight to Cobb SoCal and have Jon dyno tune it. With E45-E55 I think he could get gains close to if not better than 'the smoking tire' results and that car has a downpipe on it. I don't think the downpipe needs to come off. Out of curiosity I was able to increase hp/torque by increasing the boost slightly 1-2lbs, but I haven't really tweaked my base tunes yet.

Here are my base tune just for reference, the numbers are close to what you're seeing with your tunes. Below are base runs for Stage 0, OTS Stage 3, and OTS Stage 3 w/E40. My only mods are intercooler and downpipe.

I agree. I'm going to put in the 2J racing intake and then the DHM crash bar and IC, and make another run and check it on Vdyno. If I'm not happy with the results, I'll go to Cobb and get them to dyno tune it for e40. I really cannot see the 2J racing downpipe and FSWERKS exhaust being whats reducing my HP numbers. I checked with my builder of my other car (Adam at ST Performance) and he said if the cat is clogged, pull the upper O2 sensor, and stick a boroscope down it to check, without having to pull the DP. I plan on doing this, this weekend. I checked with the OEM DP, and my boroscope head fits just fine.

Just putting it on the So cal dyno will pretty much add 25whp :0 lol.
205whp on pump gas is pretty dang-alang good for realistic numbers.

I still can't speak for the stock turbo, but my turbo has really come alive in the 3200-5700rpm area. I was throwing everything i had at it to get to 27psi at 5800rpm back when it was cooler, now I'm doing almost everything I can to keep the boost down in the 4,000rpm area for my 93oct no-meth tune that I'm doing right now in the 90degree Florida weather.

Not saying its a god sent to any other turbo, but the 2J intake DRASTICALLY changed my car. I thing DHM intercooler would drastically change my topend as well as making it possible for me to run E20-E30 and make more power (because my fuel pump wouldn't be maxed). So I think you're going to be happy with those two mods.

As for dyno measurements.... 205whp is pretty good on 93oct and I wouldn't feel one bit bad about that at all. Lots of people make less power than that but do not post it because some "generous readings" of the past have made them feel their car isn't upto par or where it should be, when really.... 200-210whp of honestly power is pretty good on the stock turbo.

 

[Sourskittle]

Also... Ambient temps are a HUGE factor. No one is giving that factor the credit/blame it deserves. It can easily swing 20whp from a dry cold night to a blistering (or mildly) hot humid day.

 

[westcoaST]

I'm getting 187 on Cobb stage 3 with 91 octane. The 205 to 210 is on e40 with temps around 50 - 60F. I test really early in the morning when no one is around. What about the electronic recirculation valve opening prematurely? Any way to check for this Sourskittle?

Russ and i both have pushed 29+ psi though the bov. There was a time that I had a different issue and thought it was the BoV but it was not. I also used to run more aggressive BOV settings. That proved to be a waste and lead to un-needed wear on the turbo via extra compressor surge. The bov, while an issue on other platforms sometimes, has proven to be pretty dang good in my opinion and experience.

I JUST NOW pulled this from my 93oct no-meth tune. 245whp was with 69 degree temps. 225whp was with the same tune ( no reflash or map change ). Its just 88 degrees here. So... 19 degree temp made a 20whp difference.

Keep in mind, this is my car with my settings. I personally have inserted a lot of de-tuning for high ambient temps that come on automatically ( basically, when my intake air temps go above certain temps and/or may charge temps get above my settings, they cut a set amount of wastegate duty cycle ( aka boost ).

Hotter outside? Automatically less boost.

Pointless side note.... This is 93oct revision #1. No where near done, but I have to ensure a long safe knock free operation. The car hates 93oct. It hates these crazy high ambient temps. The OTS and stock tune hates high temps. This tune/car really really is meant to reduce power as temps increase in any area ( mostly, stock this happens via timing advance reduction ). Because I'm dead scared of 93oct, I'm cutting boost since my timing is already set incredibly lower than it was on E45.

Ahhhh... Rambling.... While anything below 70 degrees tends to lead to better and consistent power, Randy also has to factor in that IT WILL BE HOT SOON. So if he builds a tune on the razors edge for you at 70degrees, what happens when its 90 degrees ? Knock corrections, and at the very least a customer complaining, and of course, it could lead to engine damage if your not watching it. He has to play it safe just like Cobb with OTS tunes.

 

[Sourskittle]

Ok. It won't let me upload the pic. But same rpms, 20whp difference.

 

[Hijinx]

Something seems wrong... I was making 199whp on a dyno at 98* running 93. But, that was with Panda Motorworks.

We should be looking at the deltas. Do you have logs with Stage 0 OTS, Stage 3 OTS, so that we can compare and see if your gains with the E40 tune are within reason?

 

[westcoaST]

I only have a recent stage 3, 91 octane log, and several e40 logs. Change the extender to .csv and load them into vdyno. Let me know what you think.

 

[koozy]

here are your 3 logs.


westcoast's Stage 3 OTS vs westcoast's E40 e-tune.

the gains all look within reason compared to gains I've been seeing also.

 

[iso100]

What are your charge temps? I know the levels intercooler is pretty small. I'm getting 207hp on 93 octane with Randy's tune that's in progress.

 

[westcoaST]

About 7 to 25 deg above ambient depending upon the time of day. I'm changing over to the dead hook IC as soon as I get it, also 2JR intake. Should be sweet.

 

[westcoaST]

Koozy your a tad low on my weight. S/B 205. Third gear pull about 60 deg F.

 

[koozy]

updated weight in previous post.
