Well not sure where you are located or what the DA was but I ran 11.94 ET with a completely stock engine internally with just headers, stall, 3.70 gears at 3,665 lbs.

I hope this helps!

That STOCK INTAKE is really killing you and is a SUPER RESTRICTION on a head and cam car! You still have the ls1 intake! Upgrade that to at least a ls6 intake (ported ls6 would be better) and ported throttle body. If you really want the best results and the most HP go with a ported FAST intake and a nick williams throttle body. You will see a drastic difference!!!! Make sure when you swap your intake and TB you get your car retuned for the best results! Goodluck :) Also do you have an aftermarket CAI or stock?

Depends on your budget? If your on a budget you can buy a nice ported ls6 intake and ported TB combo that ive seen sold on here for about $350 min to about $400 max.

If your not on a budget I would say a ported FAST 90 or 92 with a Nick Williams throttle body. Another suggestion would be to go with the new FAST 102 intake but there seems to be mixed reviews on it for a stock 346 CI motor. Some ppl say its overkill some ppl like it. You would be good with any of the intakes mentioned though and it will be a a significant increase from that stock ls1 intake/TB. Your leaving alot of HP/TQ on the table with that ls1 intake/TB man.

DAMN NICE TO KNOW how will my ET times vary?

what was your 60'? that mph is good for at least 11.70's

1.78 on mt street radial 2's

Still even with the stock intake something is not right. The car is down on power or something. How much experience do you have with porting? A bad port job can hurt power. My car goes 12.2 @ 110 on stock LS1 intake and stock cam and stock 853s.

not much but i did feel the difference over stock 241 heads. it may just be the heads though i didnt polish them as much as i should have.

This could be true a bad port job could hurt power although we dont know the DA you ran in vs his. He could be running in really bad DA which will result in a much worse et and trap speed. There are head and cam full bolt ons, ls6 intake, P&P TB, gears and stalled cars that trap only around 114-116 (possibly bad DA) so considering OP has the stock ls1 intake/ TB trapping almost 114 isnt bad at all.

OP what HP/TQ numbers did it make on the dyno?

it has never been dynoed. but changing from the previous tuner to the one i have now (flaco) i gained 2-3 mph

work on the 60' for sure. what size MT radials? what brand stall? what other bolt ons do u have? what do you have for suspension?

Aw man.. Car still has alot left in it. Any head and cam car needs to be dynotuned for maximum results. The more power you add the more that ls1 intake becomes more of a restriction. On just a stock car (98-00) ppl swap over to the ls6 intake a dyno it and see nice gains so you will see really good gains with a heads and cam car rather you decide to get a ls6 or FAST intake. Add a ported intake and ported TB then get it dynotuned and it will definitely be a night and day difference!

sounds like a deal i also have a 370 s10 with ls1 intake i should upgrade it as well.

ttt! more help please!

anyone else???? point me in the right direction thanks!

About? No it isn't up to par. Intakes have been suggested. Work through it

so its my intake that should be worked on?????? will an ls6 suffice or should i go bigger????

Ls6 intake, p&p tb and a tune will work fine for you. If you don't hit 11.9x or better after that I will kick myself in the dick.
