Great numbers.

I feel ya brother, a year long tour paid for my build. I stayed with a LS6 intake and P&P TB till I needed bigger injectors and a deal on a fast 92 came around.

post your build in the 408 sticky, get some track times up

jealous of a 416 with a LS6 intake? no thanks, I have a FAST 102 on my 416. My stock cube LS1 with H/C/I made the kind of numbers this guys 416 did.

OP, sick numbers considering the LS6 intake!!

Cool story bro, you want a cookie? Do you sleep better at night with your Fast 102?

Everyone builds their cars at their own pace, OP could easily upgrade to a ported FAST 102/102 when he is ready(cash and time) and gain optimal numbers.

Ryne really knows his stuff.

I saw his Vette run at Irwindale Raceway & it ran like a Rocket ! Ryne also built a 240sx that has an LS7 427 in it & that that car ran that evening also... all i have to say is Holly crap... That thing was so Friggen fast i couldnt believe my eyes...

^^^^^^

Ps I hold my FAST 102 tight at night, until my 416 can take over those duties.


OP congrats on the numbers, I know the times are tough and those damn intakes are PRICEY to say the least but hey save a buck here and there and you'll see what I mean when you slap it on. You'll fall in love with your car again!

i agree with the fast but...To make my second point...my car now spins my 315s like they are not even there first gear at about 3800 forget traction now my focus now is useable power i dont care if you make 1000RWHP i care what you make and can hook on the street. 3 note for all you LS3 head is the only way to go people...i built my car for the purpose of cornering, and the lower rmp range for trq. I am not big into drag racing it has its place in the world..but for me i care about not only making power but driving it. Any rich *** hat can go buy a twin turbo vett and think his a bad ***.. but as soon as you take him to a autox or open track day there is a big difference in owning a powerful car and being able to drive your powerful car. you can not replace the driver mod

i have some great info for you considering ls3heads vs ls1 stlye heads in the new carcraft Mag ill buy it tomorrow and scan the article so you can read it

congrats on the build, racerfox!

another less expensive option is to have TPiS mod your ls6 intake with a 90-92mm snout, and put a tb to match it. this is what i had at first with my 418. with a coolant leaking cyl 8, it made 507rwhp/484rwtq, 450rwtq @ 3000rpm!

i was able to get a 102 at a decent price. though i am not done tuning it, i am not that convinced on it yet.

again, congrats and enjoy!!

EDIT: my cam is very similar to yours, and the heads were WCCH ls6 with 63cc.

T.Man

I said the very same thing on the first page.

It may not have the same "lungs" that a 90/92/102 will past 6500 but under that, it should go head to head if not do better.

jegten

really?
that's funny! sorry i didn't see it.

that is the exact range i built mine for. and to be honest, if i don't figure this out with the tune, i might just go back to that setup. it just does not feel that torquey at the bottom. my ls6 was ported and had a NW 92mm tb. loved it!

racerfox

your cam selection and cylinder head mid range lift numbers will determine your low end trq then an intake will that's why i did not go with ls3 heads i do not believe that they make more power down low then a ls1 style head

the only reason i still have a ls6 is money

next step is NT05R's for the rear and a new ford 9'
i am to afraid of sticky tires with that trq and a stock 10 bolt with 170+ miles....

Interesting thread. I have the same cam other than 114+2, that maybe significant.

A good cathedral style head, ported Fast 102, NW 102, 1 7/8's 3" mid & rear.

Really interesting to hear jegten comments of potentially going back wards with larger Intake & TB. Ive had discussion with other builders that agree & comment just going back to the 90mm TB is better with the Fast 102. Or a cam change that fits that combination better.

I'm finding this cam rather nasty from a street manners side & it is probably aggravated with the large Intake set up.

jegten

iirc, intake runner length/size also affects torque. hence, the difference i am finding.

money was the reason i had TPiS mod my ported ls6. the financial feasibility of the 102 is the reason why i went with it. given my >6500 rpm range, i could go either way. but now, i am wondering if i should have stayed with my initial setup. just sharing my experience.

jegten

iTrader: (22)

my cam is also a 243 but with a little more top duration, and very tight lsa and icl.

the 102 has shown smooth performance midrange to 7k rpm (which i went there by "mistake" lol). <3500 rpm, i have notice a difference. maybe it is in the tune, that's why i am still working on it before making a decision. there is a huge difference in the tune, i found, >3200rpm.

i am really hoping i can get the power back down low, b/c my engine bay now looks purdy! lol who cares about performance now! haha

oh! i spent quite a bit of time on the tune for driveability (sp?). so, aside from the huge torque, it is nice. though, it does seem i had to "learn" how to drive the car again. lol

my tune is sp and i love it ryne spent at least 4 hours dyno/street tuning it it bucks at around 1500-1600 rpm with that cam but other then that is great
