Made it to the track tonight... needless to say im very disappointed

First pass was the fastest pass and the car was running so rich it was bogging so badly by the third pass we packed up to and left

1st pass 13.36 @ 103

2nd pass 13.41 @103

3rd 13.88 @ 100

First 2 passes 60 foots were 1.85s and 3rd was 2.0

Pretty depressed about it but i am adding a blower in the next couple weeks and wanted to get a baseline.. so i didnt jet it down even though i would have picked up et

 

Bummer man, we were definitely hoping for better results for ya. Any idea why it was loading up?

 

Jets Are most likely too big, when i had smaller jets in it, it didnt pull as hard as it did now. The wideband read full rich and was 11.7:1 by the traps.. since im going blower i will just have the carb shop make me one and it should be pretty damn close out of the box.

It also bogs pretty badly out of the hole so i know it can 60 foot better and easily be in the 12s

 

When you going back? Should be much better if you line out the fuel, you already know.

 

due to work i wont be able to make it for another month or so. but by then i hope to have the blower on.

i started it to take it off the trailer and i need new plugs they are so fouled out.

 

Well it was a baseplate gasket, so i will try to make it with this set up again... the soonest ill be able to go is the 17th. I am going to try like hell to get it under 12.50s.

Also i am using the wrong plugs, vortecs take a longer reach plug so ill give that a whirl too

... and pick up a line lock lol

 

Check for wot. I had that problem went from 12.20's to 10.90's

 

Sorry to hear about the times! I struggled too at first and was right where you were at. Few modifications and some tuning and you see where i am at now. I'm sure you'll be moving alot faster with a blower anyway,lol.

 

I was thinking about this too as it seems pretty loose

 

Man we have been making some progress on this board lately! Get those little issues worked out and get back to the track man, that thing should be way into the 12s.

 

I was thinking about this too as it seems pretty loose

Dad just ordered the msd atomic system so ill see how that works for him

And greg it does suck, the car next to me ran a 13.10 with a 1.96 60foot.. he also trapped 103 so i know the car has easy 12s in it

 

Dad keeps trying to talk me out of the blower and buy a new transmission and 4k stall instead. He thinks i will kick myself in the *** if i never know what the set up was fully capable of... what do you guys think?

 

What does the tire/gear/converter situation look like? Also, what, if any, suspension miss?

 

Locker, 4.10s , 3k stall, mt et streets 28x11.5s

Suspension.. adjustable torque arm, lcarbs in middle hole, lower control arms, and air bags at 8 psi

Thats it for now. I dont know if a set of 90/10s would be a good investment for up front?

It spins out of the hole every time also

 

how old are the tires? how much psi? that thing should hook on ice

 

The tires are like 5 or 6 years old... they are almost out of tread and @ 16psi

 

I think you have alot more in your combo. I think it depends on how fast you wanna go? 11's youll be fine, but 10's all motor is probably out of the question.

Also i go between my month old 26" 275/50/15 tires and my 4 year old worn out 28" tires and i pull 1.6x 60 foots with both consistently and run the same mph. Not sure how or why, it just works. Also the only suspension mods i have are sfc's and lca's with relocation brackets (in the middle hole) and a panhard bar.

 

If i want 10s i will need a hell of a lot more cam, compression and head..i should find out shortly if im getting hired where my dad works in which case i will have a lot more money to play with

 

I know my compression is hurting me? Who makes a set of heads that will raise my compression from roughly 9.3 to 11? Obviously aluminum and at least a 195 runner. I can only find 55cc combustion chambers for l98

 

I have tires that are 5 years old, but they are in the shade deflated not in use, you take care of yours?

 

They were on my dads chevelle which is inside and on wheel dollies in the corner.. they seem a little hard but other than that like normal.. sidewalls are still like brand new

It could just be the track too, it is larue we are talking about. The track has no tech inspection and has small potholes going through the traps

 

5 years old? throw them away.

a better track would help, but you're down on mph...that thing should go 108 or better. so double check WOT. where is timing set at?

 

Timing is set at 34 all in and i verified that it does go wot with the pedal

 

shift points? what heads? vortecs? have you tried any more or less timing at all?

 

I'm shifing about 5800 and rolling through the traps at 5500... I tried moving it to 36 but i. Don't know if it liked it bc of the vacuum leak

 

I'm in the process of putting the msd atomic system on then i will see how well the car really does run

 

Thought you were doing a Carb Shop carb and blower?

 

I was going to, but this way I never have to buy a carb again. I will know what the set up is really capable of. I also installed a line lock and shed a bit of weight

 

Well that atomic system is a piece of garbage... taking it back to jegs

I'm not sure what to do at this point as i have wasted so much money for all the other stuff for it.

 

Umm, details?

 

I put it on and I fouled 3 sets of plugs and it never ran. The bad part is the msd tech line told me it was timing related which I drove it into the garage before I started the swap. I suppose ill be switching back to carbed.

Oh I had spark and fuel, it was like it gave too much fuel at one time and flooded the engine. When I called jegs to tell them I was bringing it back their response was " oh great, another one"

 

Well that sucks...we were looking at that as an option for a dd we have...

 

Hold the phone...
The gas I put in the tank, had water in it. A month prior a tree smashed through the roof of the shop and the gas cans were laying under the hole. Needless to say I couldn't light the gas with a torch.

I'm going to try to put it back on today

 

You have been having a taste of the way things go for me. Hang in there and keep us up to date.

 

well i got it back on and it runs!!!!!

it drives very smooth and better than the carb did. it idles at 750 very well.
i got the injector duty cycle error so i had to turn the regulator pressure up. it said 400hp engines start at 60psi. i started at 55psi and i just turned it up to 60 psi. it would spit and sputter when i was all the way in it.

after i get the bugs worked out im sure it will be flawless. i got a video and will try to upload it now

 

just a quick video,

btw thats the smog pump, not an exhaust leak lol

 

Those systems are great I have installed them for customers but they always seems to take a while to sort themselves out on the higher HP vehicles. Definitely not as fast acting as you would think!


Though it sounds like a couple minor jet changes and some suspension adjustments and you maybe could have netted alot better time for less money spent. But hey the atomic system should work well for future upgrades!

 

Sounds good man, I'm glad you thought to try it again. That system is supposed to be awesome.

 

Well the fuel pressure is at 65 psi and no more sputter. It is a completely different car now. I will be in the 12s now for sure.

 

Awesome! I'm excited to see your times. We can compare the newer technologies in your system, to the old style q-jet in mine. If yours runs good, i might have to invest in one one of these days,lol.

 

Sounds good buddy, looking foward to making it to the track again

 

Will be making it to the track again tomorrow. It will be the last time going t.o the track with this motor. Dad is putting his chevelle back to stock and wants my mild motor for his 383, also giving me his tci 350 trans with brake and 4k stall. Should put me deep in the 11s

 

well nice! lol

 

There was a guy in the Alt Intake forums that was having all sorts of tuning issues with his vortec and his plugs were the wrong reach (like you said yours was.) That really freaks things out.

 

Well I didn't get to run it, the car was sputtering again. I figured it out though, its vapor lock. My fuel filter is holding heat from the exhaust. Going to wrap the exhaust and filter

 

Wrapped the exhaust, fileter and added a set of 3 way adjustable rear shocks today. Ill find out tomorrow if the vapor lock is fixed
