chiplee Posted March 16, 2008 Report Share Posted March 16, 2008 Ok, I've been tinkering with the hawk today, getting to things I've literally been meaning to get to since I installed it like 6 years ago. I started out by calibrating the TPS, or messing with the TPS calibration table just to make it smooth. I had some strange percent corresponding values up high where 4.3v equaled a higher percent open than say 4.4v. In other words, a 4.3v reading from the TPS equaled 92% open, and a 4.4v reading equaled 90% open. I actually had some pulsing in the upper RPM that seems to have smoothed out, could be my imagination. Then I corrected the whole map for the percentage overall trim I've been driving around with, 12%, instead of driving around with trim in there, now it's running on the map with 0.0% in the trim. I know only a few people will follow me here. The point is that something about these minor changes seems to have been a BIG frickin' deal to my car. I can't keep traction in 3rd now and it feels faster, alot faster. I have the water/meth installed and running too so perhaps it's all three things and the fact that the water/meth (rainx windshield washer fluid) is upping the octane. Oh yeah, and I added +1.4% overall trim to the timing curve too. I saved the old map for the roller cam comparison but I think I might be dangerously close to 400whp with this setup, especially after I get the 2.25 inch stock intercooler bottleneck out of the system.

emagdnim Posted March 16, 2008 Report Share Posted March 16, 2008 I have a real intercooler for you, get that crappy POS off that car and go to 3in pipes. Link to comment Share on other sites More sharing options...
Fanta Posted March 16, 2008 Report Share Posted March 16, 2008 rainx windshield washer fluid is a water/meth mixture? O_O Link to comment Share on other sites More sharing options...
chiplee Posted March 16, 2008 Author Report Share Posted March 16, 2008 rainx windshield washer fluid is a water/meth mixture? O_O yeah, a pretty stout mix too. Anything good to -25 degrees should be close to the legal limit of 35% methanol content. Boost juice from snow performance is like $20/bottle and is a 50/50 mix. I mix that 50/50 with rainx washer fluid to keep costs down and it seems to perform almost exactly like boost juice. maybe even a little better. I think heefner was suggesting more like a 70/30 mix of water/meth anyway. What I'm using should be close to 60/40. oh and sam I know man. I've been stacking up parts trying to get this cam comparison done without changing anything else in between. Going to the dyno next monday to complete that and then the intercooler is gone. The real difference will be in flow though, for me, not cooling. The water meth system I'm using could all but replace the intercooler really. I'm really tempted to install temp probes before the intercooler and after the water injector to compare the one I already have after the intercooler, before the water injector. I bet the difference is minimal with or without an intercooler. The cooling properties of water, with methanol, injected right into the air stream are amazing. I just have to get brave enough to jack the timing up enough to take full advantage of it. Link to comment Share on other sites More sharing options...

So let me get this straight. You have windshield washer fluid in your gas tank..... Chip, you're my hero Link to comment Share on other sites More sharing options...

So let me get this straight. You have windshield washer fluid in your gas tank..... Chip, you're my hero lol, no sorry. Yeah I could have been a little more clear huh. It's a separate reservoir with a separate pump, controller and nozzle. The nozzle screws into a bung I had to have welded on the intake pipe just prior to the throttle body. The controller computer is adjustable. You can set the boost pressure it starts at and the max boost pressure. mine is set to come on at 7psi and the max boost is set at 25psi. It runs a linear increase between 7 and 25 as boost pressure increases. If I wanted more water injected at max boost I'd set the top potentiometer for a lower boost setting, like say 22, and it would reach a higher percentage of max spray as it approached my actual max boost of 20psi. It's not in the gas tank, lol Link to comment Share on other sites More sharing options...

chiplee Posted March 17, 2008 Author Report Share Posted March 17, 2008 When you get married and have a bunch of kids I want to buy all the goodies you have attached to that long block. Dad haha, ok. I tell you Randy this thing shows no signs of letting up. It always just drops down to idle and waits patiently for another thrashing no matter what I throw at it. I haven't been this happy with my car for along time. Couldn't be happier with the bottom end you put together for me. You just wait and see what it does when I get all my ducks in a row with a bigger intercooler and some appropriate tuning. Next week, after the roller dyno, the 3.90 rear end is going in. Should be a blast. Link to comment Share on other sites More sharing options...
Dad Posted March 17, 2008 Report Share Posted March 17, 2008 When I'm ready ( serious) about making some HP I will get a hold of you. I'm thrilled today just with how much better it runs... i just installed a Walbro 255 in it. Gotta crawl before i can walk. Dad Link to comment Share on other sites More sharing options...
mstieg Posted March 17, 2008 Report Share Posted March 17, 2008 Great work Chip. Check out the MPI gallery in my PICS link in my signature to see my 2.5" top entry/exit IC. It's listed for an RX7, and barely fits in between the bumper supports. Hoping to dyno the new MPI setup before April myself =) best of luck with yours. Glad your happy. Back to your original post: Which TB and TPS are you using? The standard Ford one? Are your weird TPS values due to the TPS readings itself (the potantiameter?) or something with your Hawk??

mstieg Posted March 17, 2008 Report Share Posted March 17, 2008 BTW, good call on removing the trim "adjustment". I was assuming something was messed with your actual readings, but after re-reading the post it sounds like your tables just had a few wacky numbers in there...for whatever reason. To be somewhat selfish, I'm hoping to figure out yours to not have the same problem myself. also...way to be single and kid-free. I'm with ya brother!

Back to your original post: Which TB and TPS are you using? The standard Ford one? Are your weird TPS values due to the TPS readings itself (the potantiameter?) or something with your Hawk?? dude that's exactly what I'm looking for, close enough to the same width that my current piping will bolt up, but taller and thicker. I have one of the old CNM modified stock intercoolers that is top entry like the one in your gallery. Did we talk about that thing via pm before or something. I knew it existed. I spent hours today looking for an intercooler with that design on the web and it's no where. Got a link? As for my tb/tps It's a Ford 65mm TB with the standard ford TPS, but it's from AU so it's not exactly like US models. The opening is slightly eliptical, not round. I've always wanted to swap over to a GM TB because the hawk is pre-wired to control a four wire GM idle air control valve, but the roller cam idles so well it's really not worth the trouble.

mstieg Posted March 17, 2008 Report Share Posted March 17, 2008 I forget who all I talked to about that IC before. I bought it fairly quickly after discovering the FUSO was rotted to the core --literally. :mad: Mine was from Ebay. The seller is EDTmotors I found it for ya....here's the link Looks like they made it a "Buy It Now" only option, which sucks. I was able to lowball them to $176 shipped for mine. Oh well...still cheaper than having one made. Before the rest of you chime in, I know many many ebay ICs are crap, but this is an exception and is a quality item. 3" think aluminum. Chip, I know exactly which Aussie TB you're talking about. We had that one hooked up temporarily while trying to get a Magna running to put me on the road before we found the Hawk to have fizzled out. Fixed now and the Ford 4.6 65mm TB is in there. For you, why fix what isn't broke though? Link to comment Share on other sites More sharing options...
Shelby Posted March 17, 2008 Report Share Posted March 17, 2008 tell you what i wish that Hawk program would work with the FIP or MS ecu i never use'd any over all trim adjustments eather after a short time learning the program , as for the tps if i recall right mine would read right up to about 4.93 volts at wot as for the map tuneing remember what i told you about cam changeing it calls for a total revamp of the fuel maps i don't recall you saying much about the roller , thats what i had to install on my truck but one of the g-sons talk'd me out of it , you opnions thoughts etc , friction loss from installing the roller goes right into tourqe to the wheels in this semi warm weather my truck starts so easy my2 yr old g-g-son had goten into my truck 3 times and start'd it , i finaly had to leave the keys in the house and loc it up Link to comment Share on other sites More sharing options...

chiplee Posted March 17, 2008 Author Report Share Posted March 17, 2008 keys in the truck? now, that's old school. :cool0013: yeah it is. anyway, thanks for the replies. I think/guess it's just a combination of everything at once that I'm feeling. I'm really interested to see what happens on the dyno next week. After the roller cam pulls I'll be able to fill the water/meth reservoir and load a map with a more aggressive timing curve. People have added 60+hp with that system alone because of the safety margin it adds to be spraying the mix. Not sure I'll have the nerve to push that far but with the roller, a bigger intercooler, and the water injection I don't think 375whp/430ftlbs is unreasonable to expect Link to comment Share on other sites More sharing options...
Edde Posted March 17, 2008 Report Share Posted March 17, 2008 Sounds like a helluva project there. Still plan on streeting it mostly? Link to comment Share on other sites More sharing options...
chiplee Posted March 17, 2008 Author Report Share Posted March 17, 2008 Sounds like a helluva project there. Still plan on streeting it mostly? yeah, it's still completely streetable, and that's likely to be where it gets most of its miles. Once the 3.90's are in I think it'll like the track alot better too though. I've always just wanted it to run 12 flat on street tires and pump gas and that's proven to be quite a drawn out project on my time and budget. If it holds together this time though, which it seems very likely to do, it could even see low 12s to high 11s. I might be getting another year in quantico in a non-flying billet to tinker with stuff and if that happens, the car will get very well situated.
