ported plenum and injector housings..

[Vette73]

Thinking of doing this mod to my 91....Just had headers cat back hurst shifter ,Haiback chip and intake temp sensor wire relocated to the front near the air filter done to the car..

Really liked the additional horsepower gains i picked up and of course the sound........I know a lot of members port the plenum and injector housings.......Is the horsepower gains throughout the rev range or more up on top? Im not to hung up on peak horsepower numbers,more impressed with seat of the pants feel..

Thanks....

I bought a set of injector housings and plenum from Locobob. HP went from 353 to 397 RWHP. I was pleased. Problem with seat of the pants was the winter. I parked the car with 353 hp, five months later I got to drive it with 397 hp, long delay to try to judge s.o.t.p.

Efnfast what else is done to your car? 44rwhp from the plenum and injector housing is amazing!

[efnfast]

injectors, coils and wires. But I don't attribute any of that to HP gains. Locobob did a trade with me. My car also has headers, exhaust, and a Marc H chip, but that stuff got me from 311 hp to 353. -Steve

Glad to hear you're happy wid um! Locobob is meticulous in his work, and I'm not surprised at the gains you got.

How much does Locobob charge for the porting?

[Vette73]

700 for the porting....From what I understand is you send him 700.....He ports one, sends you the plenum when it's ready....Then you send him yours...

[Locobob]

Actually I charge $900 to do a customer supplied, $1500 for my core - $600 refunded with core return. I do these completely by hand - usually 60-70 hours of meticulous work.
