AES 398 - Turbo Size EDIT:
Alright, sold my GTK-850. Closing in on choosing a turbo..
Been talking to Justin @ comp turbo. I want around 1100rwhp eventually..
Specs on 398 - LQ9 Block. TFS LS220 65cc heads. 4.030 bore, -15cc dish, 1.140ch. 3.900 crank, 6.125 rod. 9.4:1 rough cr. Custom comp roller approx 232 232 580lift 114lobe. New holley efi front inlet. Will be running on aus98 fuel (93us). Probably with meth injection. T56 gearbox. Moser 12bolt.
Will a Comp Turbo oil less CT5X 8279 suit my application? I know it's a little smaller than the usual 88/91mm. But these comp turbos flow better, spool up easier, etc. I think this one is around 142lbs/min. *HP rating is 1350
What size housing should i get?
90 T4 divided 4" V band
1.00 T4 divided 4" V band
1.10 T4 divided 4" V band
1.25 T4 divided 4" V band
.90 T6 open 5" V band
1.08 T6 open 5" V band
1.23 T6 open 5" V band
1.39 T6 open 5" V band
1.00 Tial SS v-band inlet/outlet
1.16 Tial SS v-band inlet/outlet
1.30 Tial SS v-band inlet/outlet
Any help is appreciated.
Thanks
Jeremy
Hey guys, first topic here... Be nice.
Building a 67 Nova streetfighter. Have ordered an AES398 from Fraser. Using a T56.
What is the ideal turbo size? I want to make around 1000-1200rwhp on 98octane fuel. (USA 93 octane).
I currently have 1x Turbonetics GTK-850 oil only turbo. Brand new. Kind of a waste if i don't use it. So should i buy another one and go twins?
Or some kind of 91mm single turbo? Advantages and disadvantages of both plz?
Room isn't really an issue, using TCI Pro Touring front clip. So i can cut into fenders etc.
Thanks

You could easily do twins, or go to a single GT91 if your on a budget. Either setup would reach those #'s. Twin GTK's though would allow for more room later down the road.

This is where it gets weird... There's a few cars over here in AUS running the later Tuet6000 T56 which i have. Making around 1000rwhp and holding together. If it grenades, no biggy. As long as i can get around 8-900 rwhp to start with.

Turbine size is what will be the choke point.
I wouldn't use anything with a turbine wheel smaller than 94mm no matter the brand turbo.
Doesn't matter if the bearings ride on astro glide the turbine wheel is always the choke point.

Ok but i don't want to go any further than around 1100. Don't want to stress the block/head relationship lol.. Howcome the guys at comp turbo recommend the smaller one?
This is all new to me.. I would also like to stay oil less. Don't think they do a larger frame turbo in oil less.

ray @ unleashed performance seems to be the guy doing the oil less turbo system. you may want to talk with him. i think its a butt mount but its custom and they are starting to get those down pat anyways these days.
Longrange4u with a 91mm rear mount and with the tuning of LMR and even at over 3700-3900 lbs with the iron block I believe hes going low 9's and making around 1100. seems like the enging was aes 390.....or he may have swapped it to LMR 408. pm him and ask about it.
Indeed my friend......turbine wheel is what kills most LS based setups.
