Here are the runs in the order that I ran them

The only changes since my last runs were the addition of rear coil spring airbags, aluminum LCA bushings, a jet change on the carburetor (still too rich at high rpm though), pumped up the front tires to 45 psi, closed windows, and ran at night in cooler air (like 83 degrees out)

as you will see, my traction is still terrible. The car launches much better now though, way more consistent, and zero wheelhop. I think my poor traction its a combination of a few things, 1 being my tires are probably 3 to 4 years old and almost bald 2. I havent driven in two years. 3. the road I do this on is country and the only thing that travels on it is mostly big trucks hauling construction trash so its rather dusty.
Its not just the launch either, the 1-2 shift has mad wheel spin. But enough excuses

here are the times in the order in which they occurred
2.385 60'
330' 6.071
1/8 9.075 @ 83.59
1000' 11.645
1/4 13.812@104.44 (best Mph)

This run was the first and the car was nice and cool. Only one cooling fan on. I think this run the car was developing the most power but the launch was crappy. The trap speed at the track would have been probably around 103. I can sit here and do the math to figure it out (the gtech logs enough info) but the car wasnt accelerating too hard at 6000 rpm so the speed in the last 60 feet was fairly constant (low g force measurement registered) and im lazy

run no.2
was a 13.9 @ 100.9 I wont bother with details on this run because I accidentally let off before the quarter was over.

run number 3, both fans on, no aircleaner.. manifold was probably real toasty by now, was right after run number 2
2.368 60'
330 6.061
1/8 9.089 at 82.76 mph
1000' 11.683
1/4 13.872@103.59


my final (and best ET) let the car cool for a little bit by just driving with both fans on so that it got back down to about 180 deg.

60' 2.334
330' 6.010
1/8 9.023 at 83.25
1000' 11.606
1/4 13.783@104.09 mph


theres still alot more left in this thing, its crossing the line at 6000 rpm and my wide band has me at like 12.0 afr.. i need to open the airbleeds because at 5000 rpm the afr is right on, at 5500 it starts going real rich, and the engine starts petering out fast.
Another thing, when i put my manifold back on I idiotically forgot to put the little heat riser blocker plates on the gasket. So the manifold is getting hot as hell really fast now.
Obviously traction is still a problem, with a proper launch it will see 13.4, this is ignoring the fact that I have quite a bit of wheel spin when I hit second gear

btw beastgta.. I think the jet change was good for maybe a mile and a half an hour in the quarter, the rest was weather. I know it definately gained power with the jet change. Dunno how much that is worth hp wise, maybe 10-15?


Tbi should be interesting. The carb doesnt do a very good job of giving me a consistent afr.. im going to have to play with the airbleeds which is tricky business to see if i can get it to lean out above 5500. With the TBI tuning that kind of curve is no problem. I also think it will launch better. Its a fine line between blowing the tires off and bogging the motor with the carb the TBI had much better low end torque (like under 3000) than the carb setup does.
We shall see what happens

 

I am curious what it would do at the track.

 

double post!

 

It will sit in line for about 6 hours and maybe make three runs in that time through 5 weight oil from the block of a few imports that exploded during that time frame.

if by some act of *** nothing exploded it would probably run the same exact times

 

What's the rest of your setup? . . . and welcome back. When do you go back to Oki?

 

Its a 305 .030 over
416 heads fully ported by me with stock valves, probably between 8.8 and 9:1 compression
214/224 .474 .498 cam
crankshaft oil wiper
edelbrock Torker II single plane
Edelbrock 600 cfm chokeless carb
edelbrock headers and full exhaust with no cat
T5 tranny
solid mounted torque arm
lca loweringbrackets
3.42 gears
Powertrax locker
no front sway bar, relocated battery, no AC, no rear seats or spare.. probably around 3100 pounds total or less

and thanks for the welcome back, I wasnt pcs to oki, i was deployed there for a 6 month cycle but we got extended. All told it was 380 days deployed. I am DONE with oki man I go back out to camp pendleton on the 26th. Are you ever out there?

 

Pendleton yes, Oki no. Most of my time has been spent on the east coast and Europe.

I love the weather out there, but that's about it. It's way too expensive and WAY TOO easy to get in trouble out there. I guess I'm just an east coast Marine, born, raised and stationed.

 

oh dont get me wrong, I came out of the east coast, no hollywood marine here i went to all my schools on the east coast too and then I got my orders for pendleton which surprised me and ive been way over there since.

if you are ever out in pendleton give me a holler

 

Ditto Ja!

 

Eliminate all nay sayers and take it to the track. It's still fun to race ricers at the track.

 

i can spin one and two on the street, but i dont hardly spin at all on my track. that sucks about yours...

 

dont get me wrong, i plan on taking it to the track when i get out to california, carlsbad raceway.
But you guys who think that the track is the end all and be all are sadly mistaken, not all tracks are created equal and you can run wildly different times and different tracks. From elevation change from start to finish at the actual track, to density altitude, to wind conditions, to track surface, rollout, etc youll get different times at different tracks. So if i run a 13.7 on the G tech and I go to a track it could be a 14.0at one and 13.4 at another. Ill have times from carlsbad in due time but its not going to be any slower, carlsbad raceway is a very fast track for a few reasons that I wont mention because youll swear that track is an oddball when infact ill bet a whole lot of tracks have similar conditiosn making them faster or slower (unless you are at one of the really big tracks like say gateway international where alot of money ahs been put into it) . Im tellin ya right now its going to be much faster times at that track

 

Trailer it to Norwalk

 

bah, I can race those guys down here if i want.. not that fun though, just a waste of gas unless they have really flamboyant looking cars in which case its funny to see them lose

 

you have a 5 speed correct with 3.42 gears? What gear were you crossing the finish line at?

 

about 6000 rpm in third gear

 

Wow!! She pulls pretty far into the rpms. Have you thought about possibly going with 4.10s? I know it would be killer on the highway, but you could possibly make even better times theoretically using the rule of thumb that crossing at peak power in your 1:1 gear ratio yields the best times.

 

Yeah I have.. the 3.42s are definately not for me. Ill see what happens when I get to california... maybe ill do that. We will see

 

and actually it stops pulling hard round about 5600-5700 or so, the a/f ratio goes real rich. I think that is the reason for the drop in power. Im going to see about fixing that though.

max hp is around 5500 i guess

 

Just out of curiousity, do you think it's going rich because of air flow, or because of your engine's innards?

 

well im not certain but there are two things, i think the airbleeds might be conservatively sized out of the box and at high airspeeds they arent big enough, this carb is supposed to keep a bunch of engines happy and lean isnt happy for some engines hehe
I heard something about carburetors not being able to slow down the rate that fuel is introduced past peak hp so that they end up being richer on the top end.. this was in an article in hotrod when they were talking to some tuning guru about FI vs fuel injection.. im not sure exaclty why that is the case but thats what it said.


could also be a bunch of things.. like some wacky stuff like this one choke shaft i left in the carb might be hindering flow at high rpm just enough to do this.. etc.. stuff like that.. Im not sure really. I ahve a bunch of spare carter parts though so i can test a few things


with the tbi its alot easier, you have a pinpoint fuel curve where you can adjust spots in the rpm range precisely.. no problem

 

At our track they separated the Imports and Domestics into different classes so I can't beat up on the ricers. One thing I dont understand is the Dodge Stealths run in the domestic class yet Eagle Talon's run in the imports

Pablo: what kind of TBI unit were you going to bolt on there again? a bored out stock unit or Holley 670?

 

I have a holley 670 with GM injector pod modded on there. I plan on modding it a little more for more airflow

 

HOLY CRAP, JPREVOST IS BACK. Now, if we could only find NJ Speeder

 

Not meaning to come across as a naysayer- I just prefer actual track times when gauging total car performance.

I'm sure the GTech unit (or whatever it is), is accurate as it can be, but it has to make assumptions based on inputs.

I work in Research and know full well that often-times this can alter results. Actual track times could be slower, the same or FASTER.......

Hopefully faster! I read some of the stuff on the TPI boards and they seem to have quite a bit of fun harshing on TBI and 6-cyl. track times.

Thanks,
S-D

 

Pablo, I am curious as to why you modded the holley 670 for the stock gm pod. I have heard of it before, but I would think that at, at least with the newer delphi injector pod, the holley would flow better left as is, as the gm's injector pods are much bigger leading to flow limitations I would think. Plus, the regulator is so easy to adjust on the holley unit. I'm not knocking, just curious.

 

well i dont know if the new holleys have different injectors but the holley i have (i purchased it used) had the chrysler style injectors and these things are terrible. They squirt like 8 individual streams (not like a smooth even cone) pretty much right smack dab in the middle of the throttle blade, you can see fuel bouncing off the blade and out of the tb even and the rest of it just runs down the back of the throttle blade. So I modded the tb to work with the gm pod. The gm injectors can also take much higher pressures than the chrysler ones. The regulator part of it isnt a concern to me because i run an NOS external regulator

 

eventually you will .....
