Discussion: Blacktop 20v: The road beyond 200hp

[86er]

Interesting,

Well Im about to go down the modify a blacktop path.
Standard blacktop, open trumpets slight exhaust, bit of avgas and lotsa timing made 130hp at wheels on a dynapack hub dyno.

Bit's im going to be throwing at the engine include
Cams- Toda - in 288 w/ 9mm lift ex 272 w/ 8.5Lift
Cam Gears - Toda-
Valve Springs - Probably Performance springs (yet to be purchased)
Computer - Link LEM G3
Exhaust - Hi Rise close as poss to equal length 4-1's ~850mm primary length into resonator and side exit exhaust
Head - 1996 Blacktop - Ported, cleaning up and flow (to what level yet i dont know yet)
Block - blacktop pistons, silvertop rods (may stress relieve em if i can afford to), balanced and freshened up.
Trumpets-Some form of trumpets (not factory) into a large airbox for cold air.
TRD Head Gasket & Mega Compression, TBC

And thats pretty much it. Will be running it on avgas only. Now take bets as to how much gain i can get over my 1st dyno run with the standard engine.

What is car being used for?
Have you purchased ur cams yet if not Why not use kelford race cams as they have more lift for around same duration (kelford are measured Duration @ .050" on there site and most jap companies like hks toda the way they measure it will work out to about 288 from my understandin anyone can correct me as im not sure exactly what it works out too) and 10mm lift so more power to be had and at 550US thats half price of toda pair
also use 45m diameter primaries on exhaust manifold and 2.5 inch exhaust

good luck i personally think u could surpass the 200bhp mark with tuning and a propper build

Thanks for the kind words.

Yip cam's have been chosen and brought. Now the only reason is because they were second hand (but barely used) and CHEAP. Now in regard to keflords vs Toda, as Im Local to Kelfords the cams have been taken down to them and been fully profiled, so I need to dig up the paper work which gives the true vaules at 50 thou.

Cheers

SRacin, do i know you?

[SRacin]

Hey MrRevhead,

Ya should do, I spent enuf money buying trd bits off Ya. hehe. The engine will be coming out of and going into my ke70 club car.

Havent talked to kelfords about porting, Ive got another really good engine man, who did a beautifull job of my 4K head who will be doing the blacktop.

Cheers
