Ya know I may have been wrong, I wouldn't think that the Holley system would let me be that lean.. I am goin to take it to the dyno near the end of the week or beginning of next

 

The system will do what it's programmed to do. I know with my Commander 950 I can set different parts of the map to shoot for different AFRs. I have everything under boost set to shoot for 11.5 to be on the safe side. My system doesn't self-learn like the new ones do, it just compensates based off what I set my base map to be. I don't know how the new Holley systems are setup, but I suspect you probably need to make some adjustments to make sure it is "auto tuning" for the necessary AFR under boost.

So the car is at the dyno and I am suppose to pick it up tomorrow at some point! I hope to have a dyno video for ya guys. Any guess on numbers? I have a 225 walbro intank and I think that will be my limiting factor

 

400 rwhp is where my Walbro 255 ran out of steam on a Mustang Dyno. Depending how much you turn up the boost, my guess is 400-450rwhp. Let us know how it goes!


-Paul

 

I haven't heard yet, but I'm running 8psi spring now.

 

446 rwhp 492 rwtq but I bent my clutch master cylinder pushrod? Today is not a great day

 

Any more updates on this? Have you gotten to drive it at all yet??

-Paul

 

Well yes and no. I figured out all my clutch hydraulics a while ago, turns out my adjustable pivot ball on the bell housing backed out and the clutch fork was bottoming out against the bell housing before the pedal hit the neutral safety switch and that's how the dyno bent my parts.

As far as driving it I can't drive it for more than 30 min before my gauge reads 220. Now we've been doing tests lately. My autometer gauge is between 10-20 degrees off at some points. More off at a colder temp. But now I took the stock dual fans off an bought a Zirgo 3600 Cfm single fan and it seems to suck more than my stockers?! It heats up to 220 the actual temp not gauge temp in about 15 min, I have a few things I need to do this weekend like install an overflow jug and not have the overflow capped off. Run a thicker wire to my fan just to be sure it's getting enough amps. It doesn't sound like it moves at 3600 Cfm.. It's quiet? But it's been raining for like a straight week here, so no I haven't driven it much :/

I had a similar problem. I switched to a griffin 3 core radiator. The problem persisted with that and a flex a lite 3000cfm fan. I switched the fan out for these and now if i keep the on the temp wont go over 175. I had to cut the corner of the shroud to get it to fit around radiator inlet/outlet.

 

I have a 3 core aluminum radiator already, and I can't fit much of a fan because te crossover pipe for the turbo is close to the radiator. Plus my radiator is a inch or two shorter in width to clear my 90* off the turbo

 

My core size is like 23 or 24

 

Hmmm....you didn't have overheating issues before, right? You sure you don't have a stuck thermostat or anything like that? I'm running a Be Cool aluminum radiator and a dual fan setup off an LT-1 fourth gen and even running the A/C in traffic I think the highest temp I've seen is 210 or so on my digital gauge. running down the road it's usually between 180-200. Factory temp gauge hangs out lower than the digital gauge...

I know when I did my fan research I couldn't find much aftermarket that moved as much air as a lot of the OE setups.

Did it have overheating issues on the dyno too?


-Paul

 

Since I out the intercooler in front of the radiator I've had problems overheating. And I have a new thermostat and it helped in a way but it still gets Hot. Overheating on the dyno I'm not sure.

 

Finally got my new black magic flexalite fan on today, it is 4 inches thick, and comes with a 21x17 shroud. Hopefully I get it finished the next few days and see if I overheat anymore.

 

I figured out the overheating problem, I had one of the two air dams underneath the car, I was missin the "L" shaped one that bolts too the core support. I'm running better temps now, closer too 205 now

 

Little update, temps now stay about 190 while driving normally, I start boosting it like I was the other day while racing a grand national and it just starts to climb up in temp, like to about 210? I think that's all normal though. I blew out my pass side exhaust manifold gasket though but kudos to remflex for sending me out another set by tomorrow! Hopeing to get some videos and drag slip times this weekend if all goes well. Drag way 42 here I come! I'm hoping for 10 seconds, anything in the 10s would be sweet but I'm guessing my time will be an 11.7 at 123

 

Went out to drag way 42 this weekend! They were running 8th almost all night. Here is a picture of my fastest 1/8 time and fastest 1/4. Wasn't what I wanted, I raced a 2013 5.0 mustang both of these times. I need to put my lower control arm relocation brackets on there to eliminate wheel hop. And I can't stay in boost long enough, it seems like I got full boost for one sec and then I shift. It's annoying maybe a taller tire? I was at top of fourth at the end of the quarter. Left the line at about 1400 rpm videos later. I was car 714

 

are these street tires? id say drag radials 28×11.50s at least, 50/50 rear shocks, lcarbs and tubular lcas or box the factory ones. also air bags in the rear springs help a ton. once you hook, set up a 2 step to launch higher and consistantly

thats pretty basic stuff, i would switch to 90/10s up front and some trick springs!

 

Yes they are street tires, 275 40 17s nexen 3000's. I have full tubular suspension already with koni yellows out back and adj Kyb upfront. With coil over springs up front. Once I'm able to hook up I think I'll be able to drop my times greatly. I have lcarbs they just don't fit over the moser axle assembly. I have to cut them apart and weld them back together. Are you able to set up a 2 step with my stock t5? I'm just afraid of breaking it so soon into the season

 

Of course, set it up to come on with the clutch switch!

 

I wonder if that works through the Holley efi or a seperate system

 

Which Holley system do you have again? HP? If so I believe it does have the capability to do launch control. It will also do electronic boost control IIRC. I hope to upgrade my old Commander 950 setup to the HP EFI one of these days...


-Paul

Edit: Nevermind, I looked back to refresh my memory and I see that you do indeed have the HP system. You should be able to setup launch control on that system!

 

Okay well I have alot of work I have to do to the car obviously before I can get to the times I want too. I wonder how much of a tall tire I need to run. Reason being is my motor has the rev limiter at 5800 ? It's like once I got into full boost and I hit rev, it like was a fuel cut off and rpms died super quick. Not sure I like that compared to a normal limiter. I either want to get a taller tire so I can stay in boost longer, somewhat like going to a higher gear like a 3.08 I'm at a 3.50 now? Make sense or should I try something else

 

Also I was at a show this weekend and I took 1st place in domestic class! And one of the other turbo gurus told me to take my air filter off the turbo because its robbing me of atleast 60 hp and I need like a cone with chicken wire? How much sense does it make with the turbo being in the fender area and sucking in all the dirt into the turbo then into the motor? Or will it not affect it?

 

it's stupid to run without a filter on the street, take it off for the track sure, but on the street i'd keep it on.

a proper filter will have very little effect on HP anyways (if you set it up right!), keep in mind the TTG's and FGT's all run filters on the end of long intake tubes and they are at 1800WHP

 

Ttgs?

 

twin turbo gallardos

 

True, but I think my small filter isn't doing a whole lot.. I'm wanting to turn up the boost, I want the car to be much quicker. I'm just scared to with my compression being so close to 10-1

 

Tap in a vacuum gauge right before the compressor inlet and measure vacuum (pressure drop) due to air filter. If little drop then air filter is fine.

 

So I haven't been able to hook up a vaccum port to where you said because the filter is right on the turbo and there isn't any room for a little port, it's all k&n mesh. But what I'm more worried about is my sorta backfire at 5800 ish. That's where the main over rev is set on the Holley efi but it keeps blowing out my manifold gaskets when I hit the rev limiter, and these gaskets aren't fun to chamge out. So here is a photo of the afr table I took earlier, is this okay afrs? 7.5 lbs of boost

 

I don't think the photo of the AFR table made it into your post...

 

okay sorry about that, lets try this, this should be my spark table too, unfortunately I don't know what I am looking at because idk how kpa transfer to lbs of boost. it runs great except when I hit the rev limiter it back fires and blows out my exhaust gasket. plus it runs super rich which I don't mind the smell of fuel but my eyes sting a little. if I have to deal with it I will. but itd be nice to get better than 10 mpg

 

maybe this is a better view of the table? why does it have that hump in the middle then go back up as map increase? I thought timing should go down as boost increases.

 

That timing map does look a little funky for boost. Was that something the software generated for you, or did you create it? 200 kpa = 2 bar = approximately 15 psi boost if that helps you decipher things. The AFR map looks pretty decent IMO. I'm sure it could be leaned out a bit, but it looks pretty safe to me, if the ECU is able to hit the targets reliably. My ideal goal is between 11.5-12:1 under boost. Richer sacrifices power, but is certainly safe. My car isn't there yet, but that's my goal LOL! The timing map looks kind of aggressive for my tastes, I would want to be sure you're not having any detonation with that amount of spark advance (although you are only running 7.5 psi at this point).

Again, definitely curious how the spark map was generated. Does that ECU tweak the spark map automatically as it learns, or was it just created and left that way?

-Paul

 

I'm not sure entirely if big3racing made the spark map or if it generated itself, I should probably call and ask. That's good to know that the afr table is okay. I need the car to get into boost faster. I'm doing half the psi as you and it's coming in at the same time.

 

Leaning it out some may help with spool. I think you've got plenty of spark advance to spool the turbo up quick. I'm not running as much spark advance under boost as you are. Have you checked to make sure you don't have any boost leaks? Pre turbo exhaust leaks will hurt spool too. You're running bigger primaries on your headers than I am too. Larger tubing pre turbo will yield slower exhaust velocity and hurt spool too. There are a lot of factors that can play into it for sure!

-Paul

 

sorry for my misspelling, the letters dot work ad I thik you ca see which oes. no I have not done a boost leak test yet. but im going to the racetrack on Saturday! were going out to quaker city motorsports park. supposedly its a healthier track compared to dragway42. we shall see though! I do have am exhaust leak that I have to fix. cylinder 2 manifold gasket is leakimg. I would like more stickier tires tham I have at the momemt. I have a 17x10 wheel what would yall recommend? must have dot ratimg.

 

I wish my heads fit my headers better. They keep blowing out because the head doesn't have enough material at the bottom of the exhaust port to compress the gasket there.

 

I've been having surprisingly good luck with copper RTV to seal my headers to the heads. I did have to redo the seal once, but I attribute that to the fact that I installed everything when it was fairly cold in the garage. I re-sealed them when it was warm and haven't had any more leaks....yet. Sanderson does spec RTV to seal the headers. I had my doubts but I've been pretty impressed so far!!

-Paul

 

Race day race day race day! I'm just itching to get on the track today! Nice cool temps about 59 today!

 

so yesterday was a pretty good day for me, i have about 5 races all together yesterday. first 3 were pretty consistent. no mods no burnouts 13.0 13.0 burnout on the 12.94 run though. then i blew the dipstick tube out on the 12.94 run. and oil was burning out the tailpipes pretty good. waited a while because some chrysler blew there motor all over the track. then i took the air filter off and did burnouts and i ran a 12.59 and then a 12.60. here is the video of me on the 12.60 run against a 900 hp d1sc vette. its so sad i left him by a car length at the tree\

 

Nice! What were your trap speeds in the 1/8th and 1/4?

 

Reaction .58
60ft 2.04
1/8 90mph 8.26
1/4 116mph 12.60

 

Judging by your trap speed I'd say we're putting about the same amount of power to the wheels.....You should be able to get into the 7's (in the 1/8th) easy with a better 60'! Nice!

 

What are you putting to the wheels? I'm hoping to turn up the boost soon, maybe. I want to do another track day before im season ends and I will change the tires and a cutout for the track

 

I don't know what I'm putting down right now. When I had it on the dyno around Christmas time I got 407/468, but that was with a fuel pump that fell on its face as soon as boost came on. Fuel pressure went from 40 PSI to 14 LOL. I'm getting plenty of fuel to it now and AFRs are staying where I want them, but I haven't had it on the dyno again yet. Hoping to make it to the track this coming Sunday and see what I can do. Last time I only got one run in and my ignition coil died on me. I ran an 8.4@90 in the 1/8 and the car spun like crazy every time boost came on (with BFG drag radials on the back). I've got some Mickey Thompson ET Drags for the back now and I'm hoping to get her into the 7's with better trap speed too. I'll probably turn the boost up a little on mine too, but we'll see

-Paul

 

Yeah I'm not spinning toooo horribly but that's because I'm leaving the tree at like 1500 rpm. Are m/t street radials 2 a good tire? What does 7s in the 8th compare to in 1/4??

 

Waiting for updates....

Curious to see how your set-up performs!

 

Well I posted a video above going 12.60 at 116 and I won't be at the track till the second week of October now. I am going to save up for some tires as an exhaust cutout so I can see how much that will help. Boost is stayin at 7.5 psi.

 

I was reading in zz3astros thread and saw something that caught my eye. I don't wanna clog his thread up so ill ask it in my own. His MAT he was saying were 5degrees above ambient.. I recall looking at the laptop on the runs above in the link I posted and my MAT were 134! The sensor in under the upper plenum in the stealth ram. What kind I power am I losin due to this? Any body have a reason it's so high?
