I am interested to know how much WHP people are getting from a Vortech Ti.

Please list as much relevent info as possible.

Head Unit: V-3 Ti
Blower pulley size: 3.4"
Crank pulley size: Pretty sure it was 7.625" but I will measure and update
Boost level: controller limited to 9.5 PSI
Injectors: 1,300 cc
Fuel system: Fore triple pump, return style
Fuel: E85
BoV: TurboSmart RacePort
Trans: auto, 4L60E, 3,200 stall
Diff ratio: 3.42
Mods: 1 3/4" long tube headers, cats, 3" mids, 3" Borla S-Type II

LS3 with cam and springs, pushrods, trunnion upgrade

746 WHP on a hot day, 95 degrees in the shop. The tech screwed up the previous pull so the engine was heat soaked.

Is anyone making 1,000 on a Ti?

If you have a modestly larger head unit, please post your results too. That is where this is going. If I am not able to make 1,000 and was to upgrade the blower, which one would I go to.

I will be changing to 2" headers soon and changing the diff ratio, at least 3.15, possibly lower, 2.93.

As we speak the final details are being addressed for the new engine install. 427, FAST 102, DART Pro1 280 LS heads massaged a bit by Preston at Bischoff. Callies Compstar 8 CW crank and Xtreme rods, Diamond 2618 pistons, 11.375:1 static CR. I expect the install to be complete in the next couple of days.

 

990whp was the max I was able to get out of my sleeved 427 setup with 11.5:1 CR. Carrillo flat top pistons, Callies Ultra Enforcer I-Beam rods, TSP forged crank, TSP chromoly pushrods, TSP Cathedral low profile sheet metal intake, PRC 247cc heads, NW103 TB, FIC 2000 injectors, Fore Triple Pump (3x 525 pumps). Currently waiting on AFI to finish building an AF2-102B unit for me which should give the car some extra oomph in between an F1A-94 and F1-X.

 

So close.

What SC?

 

V3-Ti on 3.47 pulley

 

Cast impeller or billet?

 

The standard cast unit.

 

864rwhp. 12psi, 3.5 griptech pulley. The tune is extremely aggressive. TI capable of 950-1000rwhp with the right setup. I know someone that’s made that. I made 850rwhp on the old Novi 1500(T trim, obviously non billet wheel).

 

864 on what engine and fuel please?

 

Not Winter, but mine made 860 on 91 with the flex fuel setup. I still run an alky meth setup for that purpose in case I am in an area with no E.

 

Meth too? You answered my question.

 

I made 843whp on an Ls2 with a 3.125" with 10% OD balancer (V2TI)

 

93?

 

sorry...93 and meth

 

same as I am Flex Fuel and meth. Made 850rwhp 15+ years ago on 93 and meth.

I’m pulling mine back to 750-800. Saving the tune for the next half mile in Texas.

The new billet wheel does not flow anymore peak cfm then the cast wheel as per Vortech. The improvement is better cfm in the mid range. That is why they do not rate it for more HP.

Yeah, completely incorrect, but ok. It flows 200cfm more. T trim was a 1200cfm blower. TI is a a 1400cfm blower. Same thing Procharged did with their P1X and D1X before Vortech did on their small blower line. T trim was an 825hp blower. TI is rated for 950hp. But hey, what do I know, only made 1000+whp 16 years ago and have had over 10 head units on my 5 vettes over the last 20 years.

 

What was your setup to make 1k?

A billet impeller of the same profile as the cast version will be more efficient meaning at the same CFM the temperature will be lower and thus providing more oxygen.

 

Actual the information is 100% correct.

I am not talking about the T trim vs the TI. No one talks about the T Trim anymore and the OP is referencing a TI not a T trim.

I'm not questioning your knowledge from 16 years ago. A lot has changed in the last 16 years. I personally have been building and racing alittle over 30 years and constantly learning to keep up with the changes. I have built everything from Strokers ,Centris, PD's and Nitrous setups. Not to mention building and racing Hayabusa's. Been in the automotive field for going 30 years. Have built other platforms along with doing turbo LS swaps. In the last 9 years owning my C6 I have run 5 different head units (2 vortechs, 1 paxton, 1 afi and 1 ess) on LS3's. I have a few friends that run C6'S with Prochargers. I also have few running custom Twin Turbo setups. Most all of my friends own and actively race C6's. All are big power cars. If you ever make it down to central TX for a meet you will likely meet them and me. I'm very familiar with all the current and last 10 years worth of Vortech , Paxton ,Procharger , AFI and ESS units. I have a good friend with a old T-trim on his C6 and have run both the V3TI and V1TI. Then ran a 2200HD (1450CFM 1000hp) to see how it compared to the TI. So I'm pretty knowledgeable when it comes to them and what they are capable of along with how the larger head unit act.

The TI up until the last few years came with a cast wheel (1400cfm/950hp rated). In the last few years they start putting billet wheels in them. I called Vortech and asked about the new billet wheel. I think the TI is a great head unit. Vortech's response was "The billet wheel did not add peak cfm but added mid range cfm. So the 950hp peak is still the same. Will make more power through the mid range".

 

Correct in the areas of the map where the design is meant to be. Typically a billet wheel of the same profile in any application will pickup 30-50hp mid range. The peak the hp will be the same as cast because the wheel flow the same peak cfm.

Your struggle to make 1000whp will be the head unit and transmission. Highest HP TI's are all M6's. Doesn't mean the car will be slow or anything. Auto's just dyno lower numbers because they rob more power. Just means it will be hard to achieve that number. Your best bet is to run a short runner intake, bellmouth, put a 3gpm meth nozzle in front of the blower and pulley down hard on it to get everything from it. I know a guy that maxed out a 2200HD 3.0/10% on a 427/A6 that made 1011whp.

 

As a concession to aesthetics I got a FAST 102 LSXr with medium runners. I know it is not much of an improvement, if any, over the factory intake, the factory intake is not appealing.

I really don't want to go to a HU that you have to spin faster than 55k. I would rather just not make 1k than go to a YSi so that is a limitation.


I think you are conflating two different ideas.


"Correct in the areas of the map where the design is meant to be." Would seem to be addressing where the shape of a billet wheel differs from the shape of the billet wheel. Which I believe is what Vortech has done with it's billet wheels.

"The peak the hp will be the same as cast because the wheel flow the same peak cfm." If the intended profile of the billet wheel is 'the same' as the shape of the cast wheel, which it will not be because it is not possible to achieve the same precision in a cast as you can when you machine the object, I would expect the billet wheel to be more efficient and produce less heating and therefore more HP at the same RPM because the air would be more dense. The fins of a billet impeller will be thinner so the impeller will capture and move more air per revolution.

I will see if I can find information on the wheel I have. I think I picked the 'better in the middle' instead of 'better at the top end'. Damn.

What I really need is to be able to read a compressor map. I have been staring at them and they still look like pea soup to me. LOL If one were to change to something different like a Magic Eye picture I will crap myself.

Good convo!

Peace
