Stock 95z28 M6 with zr1's on it
stock from the tranny back...clutch and rear and gears....

mods
k&n cold air
Hooker longtubes 2.5 ory into single 3 inch cutout(electric) then STOCK catback
EWP
and madz28 bolt on tune....(from another car and i dont think its spot on)

294 337 with the cutout closed through stock catback
303 348 with cutout open

i can still put on some asp pullies(balancer ones)
58mm t/b
and a LS1 lid setup and i think i can get 320 out of it...if i wanted to i could do rockers and possibly make 335 maybe more getting it dynotuned

Thats some really good numbers for those mods. i always thought that the 330 range was aftermarket cam territory though.

Good numbers! Though looking for over 330 may be asking a bit much.

Shon's record holding bolt-on car dyno'd 327... So yeah.. over that is most likely not gunna happen without a happy dyno or a freak

well ill be stiicking on some pullies(7-12)...and a lid(8-10)...then i should be around 320...i dont know if ill do rockers(15) if i do i will see what it makes...should be bear 330 conservatively...then a dynotune(6-7)...327 seems like cake now...(btw you forget didnt he have a 12 bolt and 4.33 eating up power?

also i asked madz28 it has 1 degree over stock on his bolt on tunes...so i think i can still add about 3 degrees and still be safe and fine with 93 octane

i got about 2hp from the under charge pullys and about 5hp from 1.6 roller rockers going by summits hp for there aftermarket parts i should be close to400hp with just boltons

TXFORMULA

i think the pulley would be worth it since you have an electric waterpump. i doubt the ls1 lid will flow much if any better than your k&n. i think the 1.6 rockers would be worthy out of the stuff you listed. ive been told by 2 different engine builders that it takes alot to outflow the stock tb but that if its matched to the intake you might get slightly better throttle response.

I got 0 hp from a 58 mm throttle body but picked up 7 ft pounds of tq.

I really really doubt you'll get over 20hp from the stuff you're chucking on there. More like 10ish. Unless you get the UD pulley incorporated into the balancer to shave some rotating weight. Also, you'll probably loose a few ponies ditching the CAI.

u should have great #'s for just bolt ons but i doubt it will be much over 330

The 9" or 12bolt he has does eat some power. Gears don't eat up power. But he has a m6.

Auto's eat the power.

m6 cars always dyno better

For the 15th time, SHON HERRON NEVER DYNOED THAT CAR! HE HAD THE BOLT ON 1/4 mile ET RECORD.

With 303 from what you have, I'd say a 320 is definately doable with the lid, the rockers and a good tune.

Except he expects 20 from UD, bigger TB and a lid, and we all know a lid doesn't perform as well as a standard CAI. It just wins the Cool Factor award The mods he has won't merit the need for a bigger TB, and UD pullies are a toss up depending on the style you go with (bolt overs or replacement balancer with built in UD). Now, a UD, EWP and rockers and I bet you'd get 20 easily. A tune more suited for what you have could net another 2-5 as well.

the ud pullie incorperated balancer i see about 10 from....
the t/b i expect a couple maybe 5 i know the stock t/b is good for bolt ons but it cant hurt....i will open then intake to match....
the rockers i see at least 10 from i hope 15+...
and the tune i have only has 1 degree over stock...i hope to add another 3 or so which should get me at least 5-10....
i can see myself getting another 25 from those mods above...

and I can PERSONALLY vouch that a ls1 lid is 1000000 times better than a lt1 CAI the lt1 cai narrows down by the abs block and limits a bunch of flow....
i PERSOANLLY gained 2 tenths on the exact same car back to back by swapping these...it was my cam only motor...so that being said i see about 5-15 from a ls1 lid

i strongly believe 330 is achieveable...not many people do FULL bolt ons....most do bolt ons like i have now...just a couple big ones...ill so all of these and i will let you guys know what it makes...

cliffnotes
ls1 lid over the lt1 cai
balancer/ud asp pullies replace stock
58mm t.b over stock
1.6rr nsa with guideplates stock
new tune


also forgot to mention if o got desperate id do a lightweight flywheel...but i prlly wont..that should gain a fe hp from loss in rotating mass

Don't quote me here, but from what I remember, the stock 48mm TB can feed 450hp. Likewise, the one guy above said he gained nothing but TQ.

And all the threads I've read on here pitting the CAI vs a Lid, almost everyone said that the CAI actually makes about 2hp more. You're more than welcomed to do the search and read then. I'd just search 'CAI vs Lid' or 'CAI vs Ram Air'.

I still say put your money into a EWP instead of a 58mm and then get one of the ported stockers (52-54mm) off eBay for like $150-185. Most include an Air Foil to boot. No need for intake modding then (intake is 54mm).

An ls1 lid wont gain any more power, you wont hit 320 even though you have great #'s.

read first post he already has ewp

Sure a 48mm TB will feed 450hp but that doesnt mean a 58 wouldnt do better.

The owner of another f-body site did tests and he was seeing more air in the manifold with bolt ons with the 58mm TB. He was just barely and I mean barely short of atmoshpheric pressure in the manifold.

Its been a long time since I saw it, Ill try and find it again.

great numbers!

you should add slightly stiffer valvesprings to that list.
