The 1st dyno is the stock engine, stock plenum & TB vs TPI upper plenum & TPI TB. Gained 2whp peak at the expense of loosing 7 ft/lbs peak. The gain came past 4800rpm with 4whp and 3wlbs/ft gained @ 5500rpm. I could definitely feel the mid range lost in power, it was very noticeable, but could hardly feel the slight advantage of the top end. On a stock engine, I would stay with the stock plenum.
The 2nd dyno is the stock engine with the TPI plenum vs the same upgraded 2.8. I immediately felt the midrange punch and the never ending top end! I was very happy to see a peak gain of 32whp and 21wft/lbs over the stocker with the TPI upper plenum, but I really got excited when I saw the numbers at the 6000rpm mark! A whopping 45whp and 32wft/lbs of torque with darthfiero's 1st chip. The 1st dyno numbers came at 147whp, after dialing the fuel back to stock setting it gained 8whp to end up with the mentioned 155whp but still rich all over the place. Right now it has the 4th chip and it feels very strong. I will dyno in the near future and will update on the final numbers.
Thank againg Craig!

I doubt it. I'm not into ultimate, max bragging power. My goal is noticeable humble engine power combined with a lightweight, nimble, balanced and predictable handling chassis with awesome stopping power and with the reliability to withstand the punishment in the hot summer week ends on my local road course and some spirited driving when I want to forget about the world.

Thats respectable. Does it have roller lifters? I bet with all the upgrades and machining it runs quieter, but the exhaust note is loud with the headers and race muffler.
nooo I dont means "bahh" like dont like, I means like good numbers on the comparison with the 2.8 stock w big plenum and 2.8 modified engines lol dont be mad loco, esta bueno ese invento y lo que yo tengo es el 2.8 de fabrica con transmission 6 cambios y tengo un GT 86 que es pa inventar con el,,,, por eso estoy observando inventos por ay a ver que hago jejejeje gracias cuidate!!!!

No rollers. It had the stock flat tappets but after one of them pumped up on me and resulted in a bent valve I replaced them with a set of SBC racing hydraulics from Comp Cams. These are adjustable from .000 to .030 preload, I have them at .000 or no preload. So, the are a little noisier than usual but that doesn't bother me. I'd rather have the assurance that when I hit 6500-7000rpm and the oil pressure pumps them up it will not affect the vavetrain clearances. On the contrary, now I have solid lifter performance in the top end.
