When Mickey Thompsons can't hold the power at 50mph you know the car means business.

Lol that was funny!

Camaro9969 07-20-2013 10:19 PM

Had a good day at the track It was hot and humid as hell but got to get all my license runs in and the last two tried out the new shocks and tires. Launched at 13psi and got this pass. As you can hear in the video i hit the rev limiter lol but still got a decent run out of it. Also this was straight 93 no mix no meth. Ran great all day. 16psi 15* timing. Now that i'm legit i'll be trying to dial it in. Still plenty left on this set up might change gear and converter up a little but want to work with what i have for now. But the Converter was not happy with the new gear change LOL ;)
Trans temp was 220 at start of this pass OUCH :( I keep hearing (theres nothing you can do unless you go 4L80e) So i will decide on that over winter i guess.

Just watch out when the weather changes. The car is down a ton of power right now that when the temp drops the 16psi and that timing will probably blow a head off on 93 octain.

Camaro9969 07-22-2013 05:03 PM

The weather and straight pump are reasons for my MPH drop? I figured it was because of the taller tire

Slowhawk 07-23-2013 10:28 AM

I think your still wrapped up on NA cars. Turbo's are totally different. The weather is illing you, nevermind the air quality at that track sucks.

You should come to NED this saturday and run the X275. Track will hook like a bastard and the sea level is a lot better.

smokinss 07-23-2013 10:35 AM

Makes sense. Guys down here with turbo cars are always messing with there tune ups cause of the humidity and heat. Then in the winter it's either cold one day then 75-80 the next.

Ya i've always heard LVD was a terrible track for times. I'm going to try my best to come up there i wanted to at least make some passes obv wont do be half as fast as all you guys but will be fun to get out there

Ya thats the fun of SD tuning lol

SLP IROC-Z 07-23-2013 04:46 PM

How do you like the drag radials? was this on friday? you should make an account on 1320go.com and keep track of all your DAs and such, makes it less of a guessing game

Slowhawk 07-23-2013 05:44 PM

SD tuning is not hard to get. Mine still runs on the tune from the winter.I turned up the boost more and didn't touch the tune at all.

There are a lot slower cars than yours running. Both races so far were won by the slower cars due to the high hp cars spinning.

Slowhawk 07-23-2013 05:45 PM

I'd also watch out on some info your getting. Cranking the timing up down low can take out a piston quickly on the street.

That's awesome ya much harder to make consistent passes with all that power!

I actually never touched my tune its been really good timing has been the same street/strip. I actually have added 8psi so far on the same tune and it looks great . I was just thinking of ways to spool it instantly on the brake but maybe a bad idea on stock pistons like you saod..I wasn't getting ibto pushing it yet only thing I changed was a little ve when i got the billet wheel. Just was ttalking about all those guys aadjusting their tune pass to pass chasing a magic number lol. :)

I love the pro's only got 2 passes out of them off the brake but launched at 13psi got a 1.4 so pretty happy with that. Ran what Don recommended 16psi and the tires barely need a burnout it seems. So with the tires and the vikings i should be able to get a decent 60' now
This was Sat. it was hot and humid i think the DA was 3500 when i checked. Alright i will make an account there just sent all my paperwork in today for the license so i'll be able to go out and make some full passes everytime.

Slowhawk 07-23-2013 10:24 PM

You have to load the car on the footbrake before the transbrake. If you just roll up and hit the trans brake it will take forever to spool. Main reason why turbo cars have manual brakes.

I also think you do not have a 2-step.Thats needed and a reason why the 60' is so slow at 13psi. At 13psi it should go on the bumper.

Ya i can def see why you run 2 rear calipers. I load them as hard as I can on the footbrake then transbrake. Also have the pulse leash just haven't used it yet. I do have a msd 2 step but havent used that either. I guess i should get my ass in gear. I was surprised it actually hooked at 13 I figured something was up. Ok next time out ill work on the 2 step and pulse box. Thanks for the advice Don :) I honestly didn't think I needed the 2 step just yet. One thing I do need to buy is an electronic boost controller just wanted to take a break from spending money but guess if I wanted to do that i shshouldnt of done a turbo car LOL

So basically have the 2step build 8-10psi at a lower rpm will get me out of the hole better? Just trying to understand better.

Slowhawk 07-24-2013 12:49 PM

Your just burning the converter without a 2-step. A lot of lost torque on launch.
No way you should be hooking 10+ boost on launch unless it just isn't launching right.

You should go this weekend, will learn a lot about turbo cars and launching ect. I know Curt with the 00 turbo Camaro is coming.

Camaro9969 07-25-2013 10:59 AM

Well I was all geared up to go even paid for a track rental tomorrow to dial it in better but just took it for a cruise didn't even really get on it and spun a rod bearing. :( didn't expect that at all but pretty bummed. How the hell that it happened on the street and not beating the hell out of it at the track is beyond me. 1500 miles street driving 21 passes most with more boost also. But its a really annoying part to go. I will habe the oil analyzed. I think instead of fixing this one ill just pick up another and swap my cam heads oil pump and timing chain over. Def a kick in the balls though. Ill have the motor swapped by next weekend.

Formula413 07-25-2013 01:32 PM

Damn, that sucks. Let me know if you need a hand with the swap.

ya its more annoying than anything like really a 11 dollar bearing goes? id rather blow a rod out of the block! LOL kidding........
Its just crazy to have it happen randomly on the street. I got guys saying just put forged stuff in but if i had a built motor that doesnt mean it wont spin a bearing ;)
Joe is coming over sat to help me get it out and tear it down. Come on by sat if your around we will be out in the garage

smokinss 07-25-2013 03:29 PM

Know the feeling. My first motor spun a rod bearing driving down the street. The damage was from all of the previous nitrous runs and drag racing. I am willing to bet you hammered most of the rod bearings while on boost and then one just had enough. Good luck on the speedy recovery!!!

Wow that must of been frustrating 11 dollar part 12 hours work just sucks! Thanks ill hopefully have it running again next week . I really wasn't spinning this motor too high and had clevelite bearings with arp bolts also the rods were resized what a waste...

Slowhawk 07-25-2013 07:00 PM

The bearing probably got beat up from knock. Running 93 at the track at 15lbs will take it's toll on bearings.

Wow that does suck!!! Thats how mine is set up now. Arp bolts and fresh bearings. Like they say though a built motor can go boom just like a stock one if its not setup/tuned right.

Then after I got a supposed low mileage motor that went KABOOM after 10 miles. It shot 2 rods out the bottom of the pan. I was very pissed to say the least.

I was logging at the track and had no knock but i was just saying the same thing about pump gas. If I'm racing either its 100+ until I go e85 and on the street i won't be pushing more than 12psi with straight pump ever again! Now i just need to decide what to do grab another or repair mine. I really was looking forward to the x275 race

Holy shit man that sucks! Its hard to get motivated again im sure. I know I lost aa lot of interest in it after a full year of this shit but I was finally starting to have fun and just got my damn license!

smokinss 07-25-2013 08:39 PM

Luckily I was able to get it back up and going.

Get that thing fixed!!! I want more videos!!!

The factory knock sensors suck. I'll rarely tune off them. These cars spark knock all the time and the factory sensor doesn't pick it up.

Slowhawk 07-26-2013 11:37 AM

You learn tuning on the street. I use the dyno and experience.
An auto with high load always lives longer with less timing with pump gas. Your tune is almost the same as mine while I'm spraying methenol with the high octain benefit.

Add methenol or run high octain and it helps keep bearings in the motor.
Also make sure you setup the correct converter gap or it will push on the main bearings.

Ya i won't be running that timing and boost on pump gas again unless I add meth. I called ati on the converter gap I believe it was 3/16" ill have to check. I know i have 1 "spacer" in there.
Thanks for the insight though Don I appreciate it. Good luck tomorrow ill be tearing down my motor all day. Lol

Camaro9969 07-27-2013 10:19 PM

Well got the motor out and just as expected found one nasty spun bearing. Actually stacked on top of each other. Couple others were a little beat. So tomorrow picking up another motor found it for $300. Haven't decided if I want to just throw it back in stock bearings and all (inspired by dudeman lol) but a very frustrating thing to fail. If I had some bent rods and was on the edge i would go forged but I really am not up for spending a ton on a motor right now so I will try this next stock bottom and hope for the best. But believe me this time around either ill add meth or always run race gas when I run 12+psi and 13+° timing. Here's a few pictures

It's hard to tell from that pic but the spun bearing shaved the crank down pretty good too, there's a nice lip between the journals for #5 and #6.

Could be just bearings but I've seen that a lot on nitrous motors. Lack of octain hammering the piston/rods.
