Here..lol the sweet music of the ole camaro. About 10 psi in this vid.

 

drove mine today !!!!!!!!! i had some video but after we finished the car we took the dirtbikes out and of course i mounted up my video camera , near the end of the ride we go for a hill climb , buddy makes it no problem on his 450 ,so me and my other buddy look at each other and i gun it , get about halfway up and get into the loose stuff and took a hard hit . they said i was out for about a min .
anyways the hit destroyed my brand new video camera

heres a few pics i took with my cell gota get the pics took with his camera from the top of the mountians and post those up ,

had to give the car and the bikes a bath , its resting place is no longer on the lift yay




the dark lumps are pieces of gravel i had to dig out of my arm



lol lot of my right side looks the same
going out on monday to do it again!!!!!!!!!!

 

Ran 12s. In 2nd rd now. Best of a 12.49 at 110mph. Launching soft.. 1700rpm. 1.9x 60 foot times. 12.5psi. Ill add video of run later

 

Easy 11 second car you got there Mark, congrats buddy...

 

Hell yea Mark, your goals are easily within reach!

 

Thats awesome! My car feels like a dog at 12psi, amazing what a top end swap can do. Cant wait to see a video!

 

Got a 12.45 at 111 lost 2nd rd

 

Thanks guys. Its a fun fun car. Feels like a rocket at the top end compared to last year.

I added 2 videos and a few slips for ya to check out. Totally fell asleep on the 2nd round and had such a horrid light. Been a long few days...to get the car tuned and ready but it ran great. Drove a 120 mile round trip also and it did well.

I love not having a screamer pipe now. All i can hear down the track is the turbo and some throtty exhaust. Love it.

Did i mention that this car is surprisingly consistent! Love that alot.

 

Cant wait but planning on hitting the track again on sunday. Gonna be 85 degrees so not sure if any better times will come out of it, but as long as it holds together im happy. Ill update on sunday.

 

Lol, ice the intake and hope the track surface is good and warm Good Luck!

 

I really dont have air intake temp problems...seemed to onlly go up 25 degrees in a full pass, thats the main reason I havent used the alky yet. Its the corrected altitude that will sux tommorow...lol

 

Well I hope you get some good runs in regardless You have a very potent setup. I cant wait to hook up my goodies, been more worried about getting the car running without problems, lol.

 

I totally understand. I hope you get it on the road again. Small problems are to be exspected on a build but one you work them all out its worth the time and effort.

 

Update. Cars running about the same. 12.50 or so. Won 1st round and am waiting in 2nd round now in the spt class

 

Nice, itll go faster. Hows the track conditions?

 

Hot and sticky. The timing system broke after 1st rd. So split pot and called it a day......... I wanted to win more rds!!! Corrected alt was between 2600-3000 ft all day so not to bad.

 

Timing set on the car or timing system at the track?

 

Timing system at the track. Hoopefully its fixed by next sunday.i wanaa make some more passes and win some rounds.

 

wow the timing system at the tracks usually dont break but i might have to come out where your racing and see this thing go where ya racing at

 

I've seen it happen a time or two .... The first time they fixed it in the same night tho ... The second time they just let everyone keep running grudge matches .. The tree and staging still worked just wouldn't give any times or tell u who won or tell if u red light etc.

My iat goes down about 5-10 degrees in a 1/8 mile pass ... Setting in staging with no air moving my iat will go up 10-15* above ambient temps .. Soon as air starts flowing they go down to ambient or just barely above lol ... But I don't have any power adders and my air filter is completely out of the engine bay ...

Mainy milan but I also race at norwalk. .summit motorsports park

 

Update. Made it to the finals for sportsman at milan yesterday. Cars so consistant even in the 85 degree heat. Goofed and lost though in the finals but all in all a great race weekend.

 

times? video?

 

Heres some slips....
1st time trial



Here is a 4th round win in the semifinals. dead on with a 7 hit the brakes at the end for the W






When your hot lapping/round robbin the passes the brakes fade when stopping from 110mph...so I really messed up in the finals going LBA. But all in all the car was constant as can be and made it 5 rounds in total. Lost to a good friend. A fellow Fbody V6 guy. 4th gen though. Was a sweet day.

Finals when I messed up vid...lol Not sure if you can see the vid as my GF uploaded it to facebook...not youtube.

Ok guys. Looking for some insite on getting some better 60ft times. Last year I could hold the car better and build boost faster. Now this year im running a big IC and getting a pressure drop, not running alky yet...exc. And I dont have the luxury of using a 2 step let alone dont want crazy fast 60 ft times. But 1.90s at best are getting old fast..lol

I just want to be able to hold the car easy in the process. So i would think that the same amount of fuel and alot less timing would help the turbo spool but make less HP.

Its not that the turbo doenst spool up fast but I need to hit the threshold for that to happen and I see that it is usually arround 2700 rpms or so. My stall flashes at 3000-3100rpm

My question is look at this timing map that im running. If I would command a lot less timing arround my 83-99 area for 2400-2800 rpms would it help the turbo spool up but yet not drag me down the track? Thanks for insite.

 

why can't you run a 2-step?

can you run a 2/3-step if it were all done by the ECM?

 

ur options are 2step or looser converter

best bet is th350 swap and a good converter for that

 

Saar I will have to ask the track officials as I am racing at a different track this year. Generally sportsman class does not allow 2 step or electronics. I racked up some points in that class so far, so I plan to run that class the rest of the season. But id still like to run in the pro class and try to have the 2 step controled by the ecm if possible. I read some links on a 2/3 step inergated into the ecm but I believe it was a 8f. Is there a way to make it happen on a $59 mask considering that ive never picked apart and modified one before? Thanks saar.

Dave I dont plan to change the trans this year but my hopes were to do a swap over the winter or just beef up what I have since I cant see myself not having overdrive.

 

the way i did it for nAst1, i essentially replaced the fuel cut rev limiter with the option of a spark cut instead. and then added multiple levels of cut/restore thresholds based on brake/clutch switch and vehicle speed.

it's all software.

 

Ok saar. I will see what I can do tonight on it. I saw the nAst1 but was a little lost but let me look over it again and see what I can do.

EDIT. saar. Im not to smart or fluent when it comes to writing in a patch. I see how to do it in tuner pro for my xdf I have loaded but it looks different and ask for different things then I see on your thread on 60degreev6

I hit patches, new xdf item... then im lost.. Ill be honest im not to familiar with coding...

 

i would be willing to write the patch up for you..... i just need to know if you can get away with it.

 

well let me ask this weekend and we will see what happends. I know I can in pro but sportsman its all about if the tech official is in a good mood as thankfully i have a turbo for a excuse.

 

Well I finally hooked up the alky injection because of the heat out there. Works great. Commanded to hit at 10psi. Ive been running 13.5psi ish at the track. Boost is controlled just by the wastegate. Not planning on using the boost controler as this is more stable all arround. And 13-14psi is plenty enough for now.

But before that I tuned in 1 more degree of timing. Can i feel the difference....not really but no KR still except if i do a burn out. So well see if it doesnt rain this weekend and i get to race it. But I feel much better that I have that alky on now to help keep my motor a tad bit safer.

Oh ya that speedo is calibrated so the MPH is true. 5 seconds 50-100 isnt too bad. But then again I really have nothing to compare it to else then drag strip stuff..so who knows it may have been slower with the alky and richer combo..

 

needs more timing specially with the alky

 

I agree. I need to make a datalogg pass without the alky and normal timing first to see what the times are, what the IATs are at the top end of the track and such. Then I will run the alky and tune from there. 20* of timing was roughly what I was using yesterday at 13.5 psi and the alky. Ave of 10.8 afrs on the pull. 11.6 ave on a pull with the same timing and no alky.

 

Ran 12.63 in the cooler air first time trial. 12.66@112mph in the heat of the day on time trial #2 and then another 12.66@111mph in the first round breaking out on a 12.67 dial in. Didnt run alky as the intake temps were well under control. Ran same tune as in the past weeks. Deadly consistent. Just driver error at the finish line but getting better at gauging my mistakes.

saar. A stock ecm tune with a 2/3 step is ok as long as its for starting line turbo spool up.

 

DO IT!!!!!!!!!!!!!!!!!!

 

PM me when you can, i have a few questions for you that may be kind of specific to your car.

 

Ok saar


I finally got in a 1/4 mile data logg. Intake temps went from 89 at the line to 144 at the end of the track. On a 85 degree day. 60 ft suxs though. Monster down track. Launching at 2100rpm.

 

Are you not running an intercooler?

That's getting too warm.

Just for reference, my intake temps will get colder when in boost than when in vacuum. My MAT sensor is just behind the throttle body, and the exhaust is directly under the intake so it (the intake manifold) gets heat soaked. The MAT sensor shows an immediate change in temp when I open the throttle. Before I put the IC in my car, my intake temps would go as high as 180* under extended periods of boost.

If you're not running an IC, put one in, even when running alky, keeping the intake temps cool before hand helps immensely.

 

Yes he is running an intercooler

 

intercooler is to far back and close to the radiator , causes the air to not flow threw it , i just had this issue on my iroc , air temps were staying withing a decent range but car was overheating since it wouldnt pass enough air threw the radiator.

i think hes running the same 32x12x4 core i am , it needs to be put up in the nose of the car

 

Wow, either it's placement as project said or it's a shitty IC. Intake temps should not get anywhere near that high with an adequately sized IC.

 

Ill be honest Ive never had my intake temps close to ambient on a 12-13-14 second pull unless it was with the alky, which goes below ambient.

Dave I moved the IC back a tad a month ago. I drove it all over gods creation yesterday(200 miles with many hard ones...lol) with 90* dry bulb temps and 60% humidity, never had a issue with the engine temp getting over 195 and its a 185 stat. The IC i believe is working fine. Doesnt help that the engine bay is cooking down track and that I really need to wrap those headers up more.

Now that I really look at that datalog the intake temps started arround 110 and went up to 140 give or take. a 30 degree rise i dont think its something to really worrie about running 12-13psi. But then again i may be wrong.

Damm look at that lag though off the line. Doesnt fully boost till top or 1st bottom of 2nd gear. I need to look over the wastegate and hot side boost leaks tonight! The MPH is way off because of the 28 inch slicks. The trap speed was 112mph yesterday on average.

 

if he has the same core i do it should work well once moved , im seeing 95* temps on an 85* day
i would like to know what his aits are pre intercooler though as that may tell a whole new story

 

move it fowards not back, the best location is up against the crash bar , or notch the crash bar and push it even more foward into the grill opening


what happens is when its to close to the radiator it builds high presure area between the fmic and rad not allowing air to freely flow threw it and then the air gets pushed around it , and it also picks up heat from the rad

 

i ment forward..lol i couldnt move it back a month ago if i wanted. Sorry its been a long day. Its about 6 inches off the radiator

 

to close

 

cant move it much more or all the bumper supports will be gone. When I raced it a month ago after i moved the ic forward the temps were 100* at the end of a pull but then again they started out at 75* since it was about 70 out and not 90* like yesterday but I know what ya mean. Ill go out and check that out dave and see if I can move it forward more.

Id really love to yank off the front bumper luvers and front licence plate to help the air get in there.
