nos tpi plate system
Anyone running the NOS tpi plate system on an L98? What mods. to the fuel system and timming need to be done. I have a hypertech chip in it, installed by the former owner. Will this provide to much advance at W.O.T. Don't know if it's a stage 1 or 2. E-mailed the #'s to hypertech they said it was to old to cross refrence. Thanks for the help.

Thanks for your help.Pull out 2 degrees of base timming or advance? Also, can that hypertech chip be custom programed to suit my needs or should I try to get a stock one from GM?

If you get a timing retard, and continue to use your chip, "at least" pull out the regular recomended 2 degree's per 50 HP nitrous increase to begin with (so 4 degrees pulled for your 100 shot)...Even pull 6 degrees to be on the safe side since your chip "could" be bringing your timing well over 40 degrees total.......you can always take a degree or so (less) out after you inspect the plugs and get it running we'll
.... No harm in playing it safe

I run that system on my 91. I have run my Jet stage II chip with no problems. I spray a 150 shot and pull anywhere from 6 to 9 degrees out while on the bottle depending on how thick the air is. My base timing is bumped to 12*. Fuel pressure plays a huge roll on the result of your tune. I run about 44# at the rail. I have run this setup for 3 years with no problems. Always run the best gas you can.

Thanks repoman, I plan on adding an edelbrock in tank pump, adjustable fuel presure reg., a mallory hyfire 6 ( it has a single stage retard), and 2 heat range cooler plugs to start with before adding the spray. Can you change the plate system to a single nozzel system and run it on a different car? Also can you increase the HP of the plate system with bigger fuel and NOS jets, without changing to bigger solenoids?

As far as the HP increase.. If it is the off the shelf system made by NOS for the tpi then you are about at the limits of the solenoids. You whould have to step up to larger solenoids to get more then 150 out of it. 150 is more then enough to spray on a stocker. Anymore then that its a crap shoot on the pistons. I have seen it done with 200 but only a few races. Im going to build a new motor this winter so the last race of the season Im going to spray 250 in two stages to mine just to see what happens LMAO! She will run like hell or loose a motor. Either way its going to be interesting.
Hope this helps.

That does help alot. The more info I have, the more reliable motor frendliy system I can build. The only change to my plan,I'm going to make is an MSD 6A, box, and Msd start/retard box instead of the mallory.Other wise a new edelbrock in tank pump, adjustable fuel presure reg. and Nos tpi 150 plate system is the way to go for my mainly street '86.

It turns the N2O on and off at set RPM's. You don't want to be spraying when the engine bogs or be spraying if you hit the rev limiter, they're around 89 bucks from Summit.
