    i just thought i would put it out there that if i ever got on the bottle again i would run a setup like this.



    http://www.nitrousexpress.com/15004-saf ... hanol.html

    The Nitrous Express SAFE (Stand Alone Fuel Enrichment) system improves the performance of any nitrous system. The SAFE system includes a one gallon, high strength, composite fuel cell that can be mounted in most factory battery trays without modification. This adjustable version comes preassembled with a high output internally mounted fuel pump and an adjustable external regulator making installation quick and simple. The regulator is also boost referencing which makes it compatible with supercharged and turbocharged applications. When used with Gasoline, this system will support up to 700 nitrous horsepower. When used with Methanol, this pump will support will support up to 350 nitrous horsepower. When used with race gas or methanol, the need to retard timing is significantly reduced. Often on V8 engines using nitrous boosts of 150 horsepower and above, zero timing retard is required. The SAFE system reduces the need to upgrade OEM fuel pumps, and will completely eliminate pressure drop at the fuel rail in EFI vehicles. The SAFE System includes an integrated fuel level gauge and all mounting hardware for a no hassle installation!

    One gallon, high strength, composite fuel cell that can be mounted in most factory battery trays without modification.
    Pump will support will support 700 nitrous horsepower at 5psi and up to 500 horsepower at 45psi on gasoline or race fuel, 350 nitrous horsepower on Methanol at 5 psi and up to 250 hp at 45 psi
    Comes preassembled with a high output internally mounted fuel pump and an adjustable external regulator
    Regulator is boost referencing at the rate of 1:1 for boosted applications
    Fuel pressure can be adjusted from 3 to 60 psi (no special jetting is required).
    Tank dimensions are 9Lx6Wx8H

    some corporate videos in the link above

    i think it would be cool to use the stand alone with methanol as the additional fuel behind the nitrous. cheaper than race gas!

    I don't have the spare money to repair with huge shots of Nitrous Phil when all goes wrong.
    I have seen Big Block Chevies Split in 2 right through all 5 mains.
    Crankshafts snapped in half.
    Take $40-100K race engine & kiss all goodbye except the valvecovers when a Nitrous engine fails blows up.
    Local guys kept goung to the bank....borrow more $$$&$$$.
    After 500,000 + Spent.......bankrupt.
    Business shut down.
    Divorce.
    Ect.

    Turbo(s) Better Power Adder & safer I think.

    i wouldnt run a huge gun on a car ever again, my mustang was all kinds of nitrous powered and if i ever did it again, i think a 200 shot would be all i want to do or run a big ass turbo and help spool it off the line spraying a 75 or 100 shot for the first two seconds.

    A setup like this would be good for my Firebird for land speed racing. I want to build an engine that I can use for road course work and then when I go to land speed races I'd run it up to about 180 MPH and then hit the button to see if I can hit 200 MPH.

    With my recent findings of Race Fuel Costs 70 Bird Man,
    We are relegated to pump gasoline,
    Methanol, & Aviation Gasoline.
    At $10.00 per gallon average nationwide for 110 octane its Crazy high.
    The Boost levels that excite Phil & Me require 118-120 motor octane.
    That good stuff is $20 per gallon.
    E85 is iffy. Really don't know what your buying & could change alcohol content tomorrow .
    No practicle way to test it at home yet.

    A Pontiac 455 core is a good start.
    I highly recommend for your 1970 Bird.
    Drop right in with no issues or custom fab work.

    Tall Deck 427 built any combo best in Chevy likely yet.
    Methanol fed Turbo be nice plan eventual.

    I've been running 110 leaded for track days, test & tunes etc. for many years. I cut it 50% with 94 octane on the street most of the time. When I build the next engine I'll probably start with an IA II block and work with Jim at CVMS.

    The Indian Adventure 2 Block has the highest Horsepower rating of any aftermarketblock from the GM Family I have seen at 3,000 +.
    If you stick with a basic 455 Pontiac build its cost effective 70 Bird Man.
    What you want to do eventual puts tremendous loads on the crankshaft, Main Bearings, cylinder walls ect.
    Most choose the 3" inch 400 mains but I wouldn't myself.
    I would use the factory 455 spec 3-1/4"mains myself.
    I am not that big into using Chevy spec rods in a Pontiac engine like many today.
    Malcomn McKeller knew what he was doing from day 1.
    If you ever talked to the man 1st hand as I have, he is a Genius.
    The other clowns today sticking Chevy parts in & calling themselves #1 are fucking retards in my Book.

    A factory 455 has huge main bearing cross sections 2-bolt or 4-bolt variety.
    Caps are thicker everwhere in all 3 planes.
    Bigger than BBC.
    ONLY CHRYSLER HEMI 426 IS STOUTER.
    FACTORY 455 CRANKSHAFT IS THE STIFFEST AND STRONGEST OF ANY GM ENGINE.
    A FEW HAVE PUSHED TO 1400-1600 HP ON THE FACTORY 455 CRANK.

    Only Pontiac V8 engines have Factory pinned doweled main caps.
    And are factory lined honed.
    All others are left rough bored from the boring bar.
    Including all Chevy.

    Few facts known by any.

    But I know. Been at it since 1987.

    keep in mind the basic concept of using nitrous to boost power, is simply that adding a gaseous mix of a high oxygen content compressed gas, along with extra fuel, that rapidly expands and cools that gas, the lowered temp, denser oxygen content and added fuel allows the compressed mixture to produce up to about 35% more horse power in a properly designed and built system, added to your average naturally aspirated engine.

    Prices are up and down on Nitrous Grumpy.
    The single plant that made Nitrous oxide was in Florida not far from You.
    It Blew up.
    Entire Building leveled.
    Was a Black Market going on.
    $50-$500 per pound.

    Most went to the Street Outlaw guys on TV.

    Been following....Most switched to Turbos since the Nitrous Plant is gone in Florida.

    All last summer it was impossible to find Nitrous oxide in Chicago area.
    Guys that had it charged a fortune.
    Turbo charged they switched.

    once you star researching this idea of adding nitrous enhanced power booster system, Id strongly suggest you select a WET system as a wet system adds both fuel ans nitrous in controlled amounts where a dry nitrous system assumes the computer control will add injector pulse duration, to keep the ideal fuel/air ratio, this is well beyond the ability of the early tpi computer and sensors to keep up with the tuned port engines ideal fuel/air ratio, demands
    as the early tpi computers calculation speeds were far too slow to keep up.
    and cars with carbs generally don,t have any controls thus the wet systems the only viable option.






    yes reading links and sub-links takes both time and some effort ,
    but you'll almost always save a great deal of other wise potentially wasted money by doing so.
    and youll also generally find you get a much better grasp,
    of how the matched components worked, or were designed to work.

    Educational to watch Grumpy.
    Testimate to how good the late Compacted Graphite Iron Small Block Chevies are.
    Usually signed off as Junk.

    Everything has its its limits as you say.

    Bad thing about Nitrous on the street....hurt the piston or engine your not driving home.
    Let alone 1 hour driving time on the highway.
    Be impossible.

    That darn C4 Corvette IRS & 700R4.
    Just junk for Street racing you know too.

    I have a LT4 C4 Corvette Intake the ex boss from the Race shop gave me Grumpy.
    It is Hogged out .
    Grumpy Race Zone Hogged out.
    Just Huge the ports now.
    It was used on the very 1st few episodes Of Pinks filmed in Joliet.
    A C4 Corvette was featured.

    Nothing hits just right & holds up like a Big Block Chevy or A Pontiac 455.
    Street Race.
