Ha . first one i chickened out and let off, second one is better. im still working on the tune AFR in the high 10's on the brake, 11.7 on the street, looks like 8.5 psi. boost, "on the tial big yellow springs.

comments! advise!









i took it out for a spin, the valve cover gasket puked out and got oil on the manifolds, "big smoke" the gasket grew and i could not get it to reseal on the freeway, so i had no choice!

Do you mind sharing any dyno numbers or graph with those heads? Im looking into those and havewnt seen many people use them on boosted aps. Set-up looks nice.

thank you, sure will, i want to get some more miles on it before i take it to the dyno. i will do 12 to 14 psi on 92 octane then 18 to 20 on c-16, i think i will run out of fuel pump around 1100 rwhp. i am happy with the spool, if you watch the vids close it spools the same on a hwy pull,

Dude I love your car.

After the time I had tonight with my car and some problems on the brake, yours looks effortless.

madmax4499

iTrader: (3)

well, thank you, i added a side pic.

what problems are you having? i wasent expecting my converter to stall so high, but i did not ask PTC, i just told them my combo and what i wanted to use the car for, i told them to make it strong and surprise me. they said unless i have over 1500 hp there is no way in hell i am going to over power or drive thru it. im happy so far. im sure if i had slicks it would make for an exciting launch!

Very Nice!!!!!

Well I wasn't having any problems at all till I started to mess with **** like an idiot.

I didn't mess with any fueling or ve tables.

I had knock retard on the transbrake like I have never had before, most I've ever had on the brake was .7-.8 and never any down track. So I figured it was because the methanol wasn't spraying until I released the brake and that it was just lean, so I changed when the methanol started to spray from 4000rpm to 3000rpm. Well it was way to low of a setting and it never spooled and starting missing, and stupid me thought it was the two step so I floored it and way over fueled the motor.

Second pass after my baseline I turned it back up to 3600 and it helped but still stumbled until 4500rpm at full boost and came alive once it leaned out. I turned it back to where it was on the baseline pass and forgot to set the transbrake on the footbrake, redlighted and didn't get another pass.

Now at low low rpm and barely any throttle % the afr goes way rich and stumbles till I give it half throttle then it leans out and runs fine.

I'm pretty sure I loaded the plugs up with fuel and fouled them and that's why it is pig rich at light light throttle and fine at half throttle and up.

Just a bad night, haven't really had any of those yet at the track so far.

Did you build the turbo system? If you want to get some time on the car better hurry, you know how the weather is around here.

madmax4499

iTrader: (3)

yes, i always have to mess with ****, and always regret it, LOL, it sounds like fouled plugs, are you really that worried about 2-3 KR? i know it is reducing your timing and a little HP, i guess if your shooting for consistency for bracket racing i see your point.

i get a little burst knock on tip in sometimes, the way i look at it, that is what it is for, to take care of odd ball situations, but i dont think an ocational small amount of KR is worth tuning out. i could be wrong im still a rookie!

what plugs are you running,

madmax4499

iTrader: (3)

yes i built everything you see. even painted it, the only thing i cant do is machine work. but i do have a small lathe.

if you ever need some welding or anything hit me up.

yes the weather wont last long, and i refuse to drive it in the wet. hell it will get side ways at 90 mph on dry roads.

Thanks. I love these kinds of builds, it's alot cooler knowing someone did the work themselves.

Fbodyjunkie06

iTrader: (10)

I dunno I thought I should be worried about any amount of KR? I just figured if it was knocking and it was pulling timing that it was close to detonation and/or could turn into preignition, maybe I'm too worried about it?

Another thing too since it has gotten colder outside, and I am using a MBC, I am not seeing 11psi were it has been set the whole time I've owned the car all throughout every gear on the street or track. Now that its cooled off I am seeing 11-12 in 1st, 12-13 in second and 15 is 3rd! Poor little stock bottom end

madmax4499

iTrader: (3)

yes, i have an EVO IX with a MBC, I always have to turn it down when it cools off, it really screams at 27 psi, but i do get a little knock, it is much safer at 24 where it belongs.

Hey mad, that converter seems kinda loose. It looks like it went to 5600 rpms at only 8 pounds. I'm fairly new to turbo combo's so i may be all wrong on this. I'm curious what rpm you shift and where the rpm drops and at what boost level? The reason i ask is because i am changing converters because mine would flash to 5500ish at 15 pounds of boost....i wanted it tighter because i plan on running 25 pounds at the track and i plan on shifting at 6500 rpms. I didn't want to blow through mine. Thanks mad

madmax4499

iTrader: (3)

i dont know, i will try to find out for you.

Fbodyjunkie06

I saw that it held at 4k at 8psi, but when the turbo's starting really spooling I saw it go to 5500. I think you will find with a 390c.i. motor that has the power potential yours does just N/A, you won't need to launch on much more than 8psi. Especially since you have an ebc you can ramp the boost in fast if you need it to hit harder off the line.

You'll have to see how the converter really acts when the fluid is hot, that's when you'll know what it really flashes too at rhe track.

If it's stalling too high for your liking you can switch to John Deere Hygard Transmission Oil. I use the Hygard lite to loosen my converter up. It's cheap at 5 bucks a qt. and 17 a gallon, and it's doesn't heat up as fast as any mineral oil based fluid I've ever used. For the price, and for what it does, you can't beat it.

The JD Hyguard tightened my converter up 400 rpms (from 3600 to 3200 with no boost) and as Fbody says it is better with heat.

cool, if i find it to be a problem i will switch it right over. i havent seen it get over 150 * trans temp with that water cooled trans cooler.
