TVS & E85 suggestions and questions
Their is no one person thats the best at tuning, porting, or building these engins. everyone has their parts to each aspect they do better at than the other.
and to go out and say that their is only one tuner that has broken 400 on a tvs is pretty childish. cause I'm sure their are some cars that have been built that noone on here knows about, or that were built but were never dynoed, like carsteds, I can tell you he was over 400hp on his engine. Yeah he don't have a dyno sheet to prove it, but to give a 500hp vette as good a run as he did, its putting something down.
Need to start shopping for a tvs 1320 or 1900 and begin building a header to accept the exhaust porting
if ur car is ur dd, i would stay with a ported and polished stock tb...the car won't be as jumpy that way...
i have ran both on a ported inlet and cnc ported outlet M62...i ended up putting the ported stock one back on..if u get a good tune the stock tb will be fine. my car made 302whp on e85, built engine ported and polished head, zzp longtube header, zzp 3" exhaust, many other boltons....
the next pull i sprayed 150 shot of nos the car spun the tires and blew the head gasket...i stretched the arp head studs. (lifted the head)

y not just get the head cnc ported and cnc port match the intake and header??
a 3-5whp gain can be had by letting the car cool off for 30 mins.
My experience with the LS4 TB
1)Put it on
2) Take off like a grandma (10% throttle).. hrrrmm this isn't so bad, whats the big deal.
3) Take off like a normal human being (15-30% throttle)... like getting slapped in the face
4) Compare 60-100 times between the two.. found the difference negligible.
5) Took it off

Im not tryin to disagree with anyone..
Im just talking from wat i know as a engine builder and designer to an extent..
if u can't make more air flow through the valve seat y would u have monster ports.. the key is to make the port in the head flow the same area that the valves will...correct me if Im wrong..i build engines for CAT that make more than a 1000 hp

But I never had a 30 minute cool off
3 pulls, back to back... pull the stocker off
not even 5 minutes later...
3 pulls back to back... on the ls4
9whp/4ftlbs gain - Is what it is man...
the point of resistance was not met at the tb. it was met further down the line. when you flat out run out of supercharger, the gains from a larger throttle body are not going to be had.
Spare block is getting the new stronger sleeves put in this month. And assembled before December according to mrbelvedere.
his idea should be sick..
him and i have been talkin back and forth about it for a lil while...Im trading him my gm sleeve puller and installer kit...
i can't wait to see how long these sleeves can hold up..

Infraredline is a prime example
yes actually...
how thick?

say what?
lets just get one thing straight
I'm nothing more than the tester; this port nothing more than an experiment.
Maximizing Head flow characteristics... your provided intelligence to this thread...
- Beyond my comprehension... Just give me a product, I'll get the maf squared away, adjust the needed parameters and see if it works.
