grumpyvette Posted July 7, 2003 Share Posted July 7, 2003 the MOST the stock TPI came with factory rated was 245hp first year http://www.rogerscorvette.com/specs/85.htm last year http://www.netvettes.com/1991.html with port work you can get in the low 300 hp range BUT ITS BASICALLY A WASTE OF TIME AND MONEY,it only flows about 200cfm stock and fully ported flows about 230-240cfm READ THIS http://www.eecis.udel.edu/~davis/z28/winter01/dyno/dyno021105/webpage021105.html heres a custom lowered version of the stealth ram efi that MAKES AN EASY 30-90 hp more than a TPI (DEPENDS ON ENGINE COMBO)with more than 1" more hood clearance (about 8.7-9" tall depenging on minor mods) http://fasterdeals.com/vette/index.html IT FLOWS ABOUT 275cfm OUT OF THE BOX AND PORTED FLOWS ABOUT 300CFM,THATS A HUGE IMPROVEMENT WORTH EASILY MEASURED HP OVER ANY TPI, WITH IMPROVED HEADS AND CAM A 30-90 HP INCREASE DUE TO FAR LOWER AIRFLOW RESTRICTION IS POTENTIALLY POSSIABLE AND SEVERAL ENGINES HAVE SHOWN 60-80 HP IMPROVEMENTS WITH MILD MODS heres the holley standard version (JUST OVER 10" tall) Quote Link to comment Share on other sites More sharing options...
warrenp Posted July 9, 2003 Author Share Posted July 9, 2003 the one i am picking up is from an Iroc-Z camero and if i can get 300hp i'll be happy. a friend of mine seemed to think they stocked between 250-300hp and i think i'm going to try and stick it in a nissan 2wd d21 hard body i would do the z conversion. to be truthfully honest. i live in maine and alot of salt is used on the roads. and i do not own a garage to store it in. i have one of those portable garages and i built a wood platform last summer so could work on my vehicles. and i think if i had a z it would have to be stored winters. and i just can't cut that. but 2wd d21's are a dime a dozen! so if i leave it out side i won't feel bad. and the full length frame is always a plus too.

David K Posted July 9, 2003 Share Posted July 9, 2003 A Super Ram or Siamese Runners on TPI engine will get rid of the flow problem with head porting. Quote Link to comment Share on other sites More sharing options...
