Updates on quest for NA TBI 305s to run 13's.

Just wondering if anyone up north has made it to the track yet?

I went last night and ran 14.51 @ 94.91 mph with poor tune and weak 60'.

I know the Englishtown is now open since my friend went last weekend.

I plan on 14.2s-14.3s come sat. at SLP day in orlando with the stock heads and TBI, will keep you updated.

As much as I'd love too, my work schedule doesn't let me run till May-June.

I'm still working on my mods for the summer though.

With these mods...
crankshaft underpulley
injector spacer
ram air ver 1
cut out
1.6 rockers
3.23 gears
currently 15.4@91 mph

Got new shocks, struts (Kyb gr-2/gasajust) springs (fourthgen z-28 rears), custom built y-pipe with pre cat cutout ver 2 and ram air ver 2 using tpi air cleaner box.

I based the y-pipe off slp's design with the y at the cat. The cutout is there too. It's stainless steel 2 1/5 inch mandrel bend.
Odds are I can pull a 93-95 mph trap speed. It's that much of a difference in how it pulls in rpm in third. I'm not sure how my times will change so I'm not guessing.

I have headers, posi, sfc's coming within the month. Not looking forward to the passenger side. Damn a/c, air tubes, smog pump etc...

I think I'll be definitely in the 14's this year. All on stock heads, intake, tbi, cam...

I'm looking to bleed even more torque out of the engine when I get my hands on an aluminum driveshaft.

305 TBI 700r4 blurple (long beach blue pearl flops from blue to purple depending on light) beast sc with no speed limiter from the factory...

Ran 14.48 @ 96.28 mph in the heat (80*+)and humidity (~80%) today at SLP day in orlando. Shifted at ~5000-5200 rpm = better times. 13's on stock heads are only a few tenths and a nice cool night away.
