ZRATED

got some new track times at Edinburg International Racetrack this past week. This is the first time I head out to the track since my new list of mods to the Lo3.

305 TPI heads with bigger springs
Air gap intake with adapter plate
Holley 670 TBI with 305 injector pod
New headman long tube coated headers with S-extentions
True dual exuast with X-pipe and bullet mufflers
1.6 proform roller rockers
Adjustable billet aluminum control arms and pan hard bar
MSD 6AL with adjustable timming control box(alows you to adjust timming from inside the car)
new purge kit and bottle warmer
SLP stall converter(2800RPM stall speed at the track)

The car is in need of some very good chip tunning it has some bugs that need to be worked. Runs were done with a set of 16" Et streets in the rear and drag lites with front sway bar removed in the front

1st run not a very good 60' time here
E.T. 13.098
MPH 107.734
60' 2.089
2nd run
E.T.12.811 good run but room for improvement
MPH 105.765
60' 1.730
3rd run messed around with the msd timming control ****
E.T 13.058
MPH 109.365 pulling hard on the top end
60' 1.917

Awesome. Great times, that's really cool to see you pulling a 12 second run! How much of a shot of nitrous were you running? I didn't notice if you said that.

Its a 125hp shot of the line

You deffinately need some chip tuning. Your MPH is wicked and good for mid 12's. Those times are amazing. Keep your fingers crossed on the short blocks life though. What does it do off the bottle?

IROCaholic

So are those times with the stock tune or are you saying you have done some tuning but need a little more? Either way awesom times for a 305 with or without nitrous.

How did you adapt the No2 after the holley tbi? Did you just go with a squarebore plate, and did it adapt to the tbi N02 setup ok?

ZRATED

When I installed my intake and holley TB I needed a chip to eliminate vats,egr,speedlimiter and I went for the fastest, cheapest way out....TBICHIPS.com oh well It runs kinda of crapy at part throttle, its mostly due to the increased air flow from the intake, holley TB, and stock injectors with AFPR
I took apart the NOS TBI plate and bored it out to the required 2in, it worked out great, I was thinking about goin with a carb plate setup since they are inexpensive
I also changed the old fuel pump with a brand new TPI unit
No new N/A times yet

If you all have any questions or need more pics just ask

Damn, on that last run you pulled some serious mph.

i have a nitrous question.

how do you control your timing for nitrous use?

and what prep work did you do to the engine before using nitrous?

colder plugs?
synthetic oil?

did u retard the timing from stock timing, or from most advance and go down from their?

do u run 91 octane?

fuel cell or just fill the tank?

ZRATED

Colder plugs and plenty of fuel are a must, I run Autolite #25 plugs which are one step colder, and a new TPI fuel pump which keeps the presure steady
Timing is controled via the msd timing control box that lets you retard the timming from inside the car for nitrous use. I started off with 7 or 8 degrees - current timing and then fine tune from there with the turn of **** and always use 93 octane or higher

Nice man! Hopefully I don't have to trash the 305 here and I can get some times on the bottle!

Mark305TBI

Nice times. But damnit man, you need to crop those pictures. They'd be just a hair less than full screen on my 21" monitor at home, but they're down right enormous on this little 15" panel.

How many times have you used the nitrous?

I thought about running l98 heads and a 100 shot on my 350.

Some people run 125+ shots on stock blocks and they last forever...then there are guys who say they will never put nitrous on stock internals....what do you think about that? Think Id be safe with a 100 shot?

ssxmac

iTrader: (1)

as per holley's web page: small block V8's (302/350/400cid) can typically accept up to 140 extra HP,

If holley claims that, im sure you could prolly run even more with out worrying too much, b/c you know that they're going to be covering their asses. 125 sounds like a safe amount to me though.

That is to broad of a statement. We have crappy cast pistons that are only supposed to handle 300hp. Many other small blocks come with hyper's which can take much more.

88Camaro350

I have the GM goodwrench lo5 replacement. It has NODULAR IRON CRANKSHAFT, POWDERED METAL CONNECTING RODS and FLAT TOP HYPEREUTECTIC PISTONS. Got that straight off the website. My compression is a tad high but I plan on getting the MSD box with the timing adjuster like you have.

I think I would be safe with a 100 shot. I will be running a holley blue 110gph pump...plenty of fuel. And a MSD 6al box for my rev limiter. With my internals you think I could handle l98 heads, lt4 cam, street dominator intake, 670 SA carb, TES headers, no cat, and a hooker catback with 100hp shot of nitrous?

I want to get into the 7's in the 1/8th. I think I could do it with all that if I can hook.

88Camaro350

OOOOO BTW:

Those are some really good times.

I know a guy that has a 2002 TA a4. Only 2 mods he has is a SLP catback and a 150 shot of nitrous. His best 1/4 mile run was only a 12.54. He even has 17x9.5 tires, 275's in the back I think.

He's gonna crap himself when I tell him what you have and what your running.

njspder

125 shot is safe for a stock motor. camaroracer1992 prolly ran 20bottles or more through his old 305 and when we took it apart it looked like new.
as long as you have nitrous and fuel pills matched correctly it is not really that huge a strain on teh motor.

not bad.....not bad at all

And what kit do you recommend NJSpeeder? The TBI kit or something else? I'm not very familiar w/ "wet" or "dry." I'm N20 skeptical.

92rsbowtie

hey, zrated, where did you find all the components of your exhaust system, if you don't mind me asking

TraviZ

iTrader: (2)

dry kit is just nitrous, but tells the injectors to raise pressure and inject more fuel

a wet kit injects nitrous and fuel independantly and doesnt have to rely on bumping up pressure in the injectors.

88Camaro350

For TBI (and carb like me) I would definetly run a wet kit. Safer and easier to tune in.

I am going to get the edelbrock performer kit. It comes with 50, 75, and 100 jets. I am not gonna go over 100 until I get a stronger bottom end. Still 100hp will be nice. I'm hoping I can get well in the 12's with l98 heads, my cam, my intake/carb/exhaust and a 100 shot. Suspension is probably what I'm gonna need to accomplish this.

ZRATED

My exhuast only runs up to the rear end and stops there but it has a very nice rumble to it
Coated long tube headman headers from American coating specialties 310$ shipped
Headman S-extensions-jegs 21$or so< these are a must
2-2 1/2 Bullet Mufflers-jegs 65$
Stainless steel X-pipe-ebay40$
45 degree mandrel bent tubing Jcwhitney.com your gona need about 2 or 3 of them I think they run 9$each
Then just take to a good muffler shop and have them add a few peices of straight pipe and weld it all in.
It fits really nice in the drive shaft tunnel, the only problem is the pipe to ground clearance over the trany cross member
But the sound rocks!!!!

92rsbowtie

do you have a sound clip?

TraviZ

iTrader: (2)

hey can i ask how and where you tapped the fuel line for the nitrous?

i know we have that rubber part of the fuel line by the driver side valve cover.

i want to tap into that but cant seem to find a part that i need.

ZRATED

Nope I do not have a sound clip yet, but you can give me a call and hear it over the phone
To the supply the fuel I used a simple hardware store T-fitting with hose clamps on the fuel line and ran it from there

TraviZ

iTrader: (2)

what kind of t fitting? was it

5/8" all 3 sides?

or what?

thanks for a quick response!

i could do it like nos does it, but thats expensive, i would need a 4an Tee and a 4an to 5/8" compression fitting..

thats like 30 bux right their :S

ZRATED

I just used a 3/8" tee and regular hose clamps our TBI systems do not run at that high of a presure
I will take detailed pics of my fuel lines if you want me to

TraviZ

iTrader: (2)

that would be awesome if you could do that.

did you just pick up the tee at a local hardware store?

how did you fit it inot the 4an line?

91RSHawaii

nice exhaust set up zrated, i was looking into the whole bullet exhaust myself, but didnt really want to run true duals, do you know if it would be possibly to use a Y pipe instead of an Xpipe, and run the fake dual exhaust off of the singular exhaust from the headers?

90RS305

True dat, true dat! I've met a few guys (they were roomates) with LO3's (couldn't get them for the life of me to check this place out ) and they were both running 175 shots. One had fordged pistons the other had stock internals and both cars seemed like they just came off the show room floor. I asked them if they had run them more than 3 times (thinking they were ing) and they both told me they spray all the time. After a few minutes of talking they had me convinced it was true, so I grew to love the mighty 305 even more...

Bruce (90RS305)

90RS305

Ohh yeah, they both said they ran 14 on the bottle...
