Called Hellion and spoke to Jeff...awsome guy.

Called Hellion and spoke to Jeff...awsome guy.
- looking at around 425 rear wheel hp
- the tuner that comes with the kit is a SCT X3 with a full tune not a base one as the site elludes too. Said that the tune should be pretty spot on but of course they do recommend a dyno run just to validate the A/f.
- upr K-member coil over kit without shock (which is what i thought)
- Basic turbo is a channel bearing turbo and he said there is no reason to go to a ball bearing turbo till over mid 600hp
- injectors very said sometimes 36 somtimes 42 depends on whats on hand but said e believes that anything ordered round this time will have 42's (flow about the same no issues there)
- fuel pump is a focus svt
- maf is a 90mm lightning maf should be good to about 600hp recommended a diablo extender beyond that
- shipping takes about a week and he will be emailing me today a list of prefered tuners and installers (i will be installing but ill post what he sends)

The 90mm LMAF will not work to 600hp, is it in a draw thru or blow thru setup? Most turbo are blow thru but I don't know how that system is setup. Blow thru maybe 400rwhp, draw thru 450rwhp but it all depends. The fuel pump might be ok but my friends 99 Cobra didn't have enough at 400-425rwhp with that. Maybe a GT is different but not sure why it would be.
might be right..looking at the install pictures it appears to be a draw through. either way at my current build with stock block and using prescribed psi i should be ok. if the pump lacks i have a buddy that has a KB boost a pump sitting around.
good catch on that though.

Called back cause you had me a bit concerned. Spoke to Mr Urist him self....
It is a draw through design and he confirmed what you said. I brought up that the jeff guy said that it would support up to 600. He said that he would speak to him but that it would if a mafia voltage extender was used as for the fuel pump he said he had no idea. Other then that they seem pretty decent.

It is 2 different power bands and when people say Hellion, Hellion does not make turbos they make kits and in many cases there kits are restrictive with small pipe work and to many bends, therfore tuning them for driveabilty at times is tricky. I cant see spending the money on a Turbo on a stock block and never running the Turbo were it likes to run. Example with twins, I have a customers car that has twin 61mm and he runs them at 7psi per turbo, imo that is useless you can run one 61 at 20psi all day. I like Precision turbos much better.
Blowers are fun all around because there is no lag and power is instant for a street driven car with a stock engine. Do not get me wrong, Turbos will make more power but with that also comes the price tag. Turbo's like to eat parts and break things as well so you need to think long term what your plan for the car is before you spend a dime. We carry all blowers and turbos so let me know if we can help. We also offer free pick up and delivery and Kevin is a outstanding tuner blower or turbo.

I understand that Hellion doesnt manufacture the head units but design kits around the TC its self. This isnt my first turbo car. But this will prob be much more efficiant than my JY twins on my 86. Alot has changed since then as that was over 8 years ago when incon was still around. as far as pipe sizing I would think that been taken into account with the efficiancy of the head unit casing, perpeller, bearings, cooling, ect. All kits are just that, kits; even supercharger kits are built for the general masses and may have pluses or negatives in one area or another.
I know I asked which direction I should go, but this was not because I did not know what a turbo or a twin screw was... but that this is my first on a modualar engine. I have run pretty much everything out there other than this new compound boost thing. the 88gt went from S-trim to T-trim, 86 gt went from T-trim 331 to twin t3/4's, 95 cobra 5.0 dss block with a KB 1.7
This 4.6 is a new animal to me as the low end torque lacks compaired to traditional pushrod engines but with a positive on the upper end of the rpm curve where turbo's thrive. reguardless looking at a
Your comment about turbo's "eat parts and break things" had me confused as this is the norm with any modification beyond manufacturers or designers specifications. Any supercharger/Turbo/Nitros ect with have the same issues when not configurd or tuned correctly within the safe AFR/HP window or the parts its supporting. when you combine racing with the need to go faster any technology used will "eat parts" as you put it.
I do appreciate your assistance...but i think i will be going the turbo route.
Fun part is I dont need to do tons of welding and play with the tables in the tweecer for 4 months.
like years ago. JD

I think I will take the summer building up a proper longblock for stand by. but as of this moment ill be happy with low 400.
I just need to focus on getting the upgrades done that i have sitting collecting dust for the last year. I think im a bit ADD get a new toy loose interest in the rest...then after a while i come back around and refocus. Last year it was the bike. Year befor that the sled.
