I went from a 14.6@96mph with a 2.3 60ft. to a 14.4@101mph with a 2.4 60ft. I know, I suck at launching. I really gotta get me some sticky tires. I'm too used to AWD launches.

 

hey what you should do ralli is take the heat exchanger off on the same day run the car.... then put it back on and run the car.... THEN THEYLL SHUT UP HAHA

 

hmmm so you were most likely spinning more ont he 14.4 run? that might have something to do with the trap as well...

also, are you just "remembering" the air and temp were exactly the same, or just not wanting to give into the fact that it might have affected it. i can see a higher trap from your mod, but to think it gave you 5 mph is ludacris. my guess is: better air, spinning more on launch, and a 1-2 mph from your mod. wow, just saw you think you are making 20-30 more hp off that mod, um... roffles. 20-30more hp is not going to net you 5 mph, not even close

 

that's too much work.

You go to the track and test your car, then you add mods and go back to the track to see what kind of gains you got. That's exactly what I did and I know that the H/E gave me 5mph in the quarter mile. There is a reason I can beat up on stage 2 cars and other stuff I'm not supposed to be able to hang with around here, and it's cooling mods. Cooling mods have really unlocked the potential of this blower set up on this motor.

If they don't believe me, then so be it. They don't see that cooling mods are a necessity and a must first mod, then that's their loss. They can bring their 2.8 pullied car and I'll give 'em a good race on a stock pullied car. I'm telling you, it'll amaze you. If you take the info I type out and use it, then at least i have accomplished something. The way I see it, I don't have to share any info. I could be just like all the other people i know and keep everything to myself and laugh at everyone else for being so slow and modding the wrong way. Or I could share what I have learned and maybe help someone else out. I decided to share my knowledge and my findings.

I'll leave it at that.

 

how do you know DA remained the same? if the baro drops say .2in then air density is a decent amount higher thus more power....a small change in shift points can also make a solid differance at the top end.

trust me man, i know a grate deal more about this car and how a heat exchanger effects it then you. a HE will help, that i'm not doubting but its not a 5mph increase.

the reason i say that is because your logic is jacked up here "It cooled the engine down by dropping those IAT's and I made more hp which in turn resulted in gaining 5mph"

please god tell me thats a typo. no IC H/E will cool the engine...... it takes a fair bit more then 10-20deg IAT drop to cool that hunk of aluminum.

that same 10-30deg IAT drop doesn't translate into 20+ whp if we say like 50deg+ (the likes you get from meth or an IC sprayer) then we can start to see that type of power differential.

the HE helped, no doubt, but there were other forces at work here.

 

hmmm 12's should be there with ya man!!!!

 

i really dont like taking up anamolus's thread like this, so if you want to talk to me more about this my PM box is waiting. I whole heartedly agree that cooling mods is a great first mod, second mod, or any number mod on our cars. you are being entirely unrealistic in thinking that your mods picked up 5 mph and/or 20-30 hp. even IF you did pick up that amount of hp you would not pick up 5mph and only 2 tenths. not gonna happen bro. i dont know what the stage 2 cars around you are running, but there is no way in hell your car would run with mine, and im stage 2. (when i went to the track in 100+ air and 60% humidity i was trapping 105)

 

so what is the gain for 5mph then? I'm guessing 20-30hp would be about right for gaining 5mph in the quarter mile. And I ran 96mph consistently before the heat exchanger. I could spin bad and cut a 2.5 60ft and still trap 96. Then after the heat exchanger, I could spin worse and still trap 101. I just gave my best times. But everytime I go to the track I run consistent trap speeds. Mainly because I launch the same everytime. I need to get stickier tires though so that I can take adavantage of that trap speed.

put it this way, I know that I gained more than 30hp from on my old talon that I raced when I upgraded the entire exhaust from stock to 3" turbo back. I went from trapping 90mph to 95mph with just exhaust. So I'm guessing that with a 5mph gain that I say from the heat exchanger, that it gave me back about 20-30hp that I was losing from heat.

 

ditto

anamolous, i wanted to be the first stage 2 car in the 12's, but looks like youll prolly beat me! good luck man

prolly good for 1-2 mph

 

ok, so I have proof that all I did was add a h/e and I gained 5mph and yet you say that I am being unrealistic. I already proved it. believe it or not. I don't care. My goal this next year is to trap 105mph without stage 2. I will be dropping to a 3.1" pulley at the smallest. I will use my meth kit and I should be able to pull 105 trap speeds off. just wait and see.

 

thats all fine and dandy, but when you wake the hell up you will realize there were other factors to add onto your mod. so you are gonna run essentially a stage 2 size pulley, spray meth, and run high 13's-low14's, congrats. quit acting like the world is out to get you and just realize we are trying to talk sense into you

oh and i will revoke all of my points if you can show me ANY other cobalt that picked up 5mph in even close to same air, with identical 60's with a 30hp improvement

 

**** cooling mods 2.0 pulley ftw

 

well, I got me some stickier tires as well. So hopefully mid to low 13's will be achievable. I'd like to improve my e.t's drastically. But trap speed is all about your power. And so far I've been really impressed with the trap speeds I've had with next to no mods. I'm still on stock intake, stock exhaust, stock tune, stock injectors, stock everything except for the h/e. But next time I go back I'll have the meth kit to see what I gain from it, then I'll go back with the pulley to see what I gain from it. hopefully 105mph traps with adding the pulley and meth.

 

dude meth is good for like 10-20 degree lower intake temps, thats like another 30hp for you! watch out 106 mph traps on an untuned meth kit!

 

that's my goal. 105mph trap speeds on stock tune,stock injectors, stock intake, stock exhaust. pretty much all stock. If I don't get it, then I'll throw that 3.1" pulley on.

 

wow, lets compare apples to oranges.

you talon made more power because you dropped backpressure on the turbine outlet of turbo, thus letting the shaft come up to speed quicker, build its PR in the compressor side and make boost sooner. THAT increase in boost timeing is the reason why you picked up power, hell my STi with my 4in apexi setup did the same thing....

but once again, this has jack **** to do with any thing related to your semi-bogus HE clames.

I'm not out to get ya man, just trying to talk some since into you here, i know a vast deal about what i'm talking about and i'm rarely wrong. i just don't want to see people going around and saying "hey my HE added 20hp!" because thats simply not true.

thats it, and thats all.

buwhahahahhaha

now thats funny!

you truly have a passion and lust to see what a static injector will do, dont ya?

 

Ok, so what you are trying to tell me, which makes no sense by the way, is that a 5mph gain in my talon is not the same power increase as a 5mph gain in the cobalt? HUH? 5mph gain= 5mph gain. It takes quite a few ponies to gain 5mph. I figured at least 20. I think I'm being rather reasonable when it comes to that assumption. I personally think it takes more than 20hp to gain 5mph, but I don't want to get to bogus. And my H/E did give me 5mph, that is ALL.


Static injector, eh, I'll be using meth so I think I'll be fine. I'll just make sure that I log everything and if I think that i need the bigger injectors then I'll upgrade.

 

Rally, your intentions are good.
cooling mods are excellent.

but your proof has holes in it.

just because you went to the track one week and ran 95, and went the next week with a cobra H/E and ran 100, doesnt mean cobra H/E = 5mph


at the end of my first year with stage 2, and very new to drag racing, i was running 14.7 @ 98
my first run the next season, after no changes, I ran 14.3 @ 101


There is only so much that ambient air cooling mods can achieve.
You have HPtuners, you can see that right in front of you.
look at your IAT2 vs advance table.

 

an0malous has a much nicer way of making my next point.

regardless of what you think, your theories behind your 5mph trap speed gains are wrong, flat out wrong.

it helped but its not THAT much of an increase.

don't "ehhh" me on the static injector issue. **** they go rite up too and past 100%IDC in stock form alone. regardless of weather your spraying meth or not. meth doesn't make a static injector "OK" it has no effect on that in any way, shape, or form. when that injector pops, sticks, or freezes you can have all the meth going in the world and your motor will still pop.

you don't have much of an idea of what your talking about do you?

I'm done here, go read a few books and gain an understanding of how an engine and fuel injection system works and how they effect one another. then you'll start to see the large holes in you logic.

 

The subject isn't about the fuel injectors. Don't worry about my injectors going static. Let me worry about that. The subject is whether cooling mods give you a gain or if they are just to keep you from heat soaking. I personally think that they do more than just keep you from heat soaking. I think they give you an increase in power because you are cooling your iat's. Cooler intake temps equal to more power. period. This seems to be a great arguement that can go on forever. I appreciate everyone's opinions and knowledgeable answers. But I have factual proof of my gains and you guys aren't going to be able to make me change my mind. when all this snow melts and I go back to the track, if I'm not deployed, then I'll get some more track times with the methanol kit and what not and I'll see how far I can go. I'll post my results then. Until then, this will be an ongoing arguement. You guys can state your opinions however you want, but I know what my facts say.

 

your dropping iat2's 15* most with that setup, there is only so much the car can do. everything is not about mph man trust me, as for the meth kit on a stock tune i don't see you trapping 105 once you pulley down yes, but stock pulley and tune nope.

 

Do you know what im talking about when i say the "IAT2 vs Advance" table?

Do you know what the timing difference is from 135* , dropped down to 110*?
Zero.
from 135* alllll the way down to 55*? a whopping 3 degrees.

its once you get ABOVE 140 that you really start to lose power.

and anyone with a pully above 2.9 should not have much trouble at all keeping themselves below that with stock cooling.
as long as they are allowing the car to cool between runs, and assuming its not a sweltering hot day.

 

ralliartist you have no clue how to drive? You say that the HE helps against heat soak and you are 100% right. Where you are wrong is that it GIVES you power, it helps you from loosing power. I don't know why that simple subject is so hard for you to comprehend. You could of picked you MPH from driving, weather, or track conditions. there are so many variables. With you logic hell you can be the first lsj on a stock tune with intake, exhaust, and a big muffler tip. So do you think that engine mounts will give you more power?

 

you are just being riduculous now. and saying I don't know how to drive is funny. I was having problems with launching at the track. I know how to launch now. I limited the boost in 1st gear and solidified my motor mounts which helped me get better traction. I have vids of me outlaunching wrx's and eclipse gsx's. I know how to drive. everytime I go to the track, I run extremely consistent. My mph is the same and Unless I change my launch my e.t's remain the same.

Oh, and engine mounts allow you to put more power to the ground as well. So you will be making a bit more Wheel Power with mounts.

and I'm sold on a h/e upgrade being a power mod. I proved it. Maybe if you try it you'll see the same effects I saw. Until you try it, I don't think you have any ground to stand on. I already proved it. Prove me wrong.

 

dyno stock then with a cobra h/e and if it show a power increase then you are correct, if not then your wrong
