red 454

HI guys
i have a harrop HTV2300 2.3 LITER PD blower (similar to a MAGNAR CHARGER)on a stock bottom end ls3
it is under driven at the moment making max of 10psi
im thinking of doing a forged lsx 454 and putting the 2300 on top
what i want to know is the 2300 good enough to give 10 psi on the 454 or even 7psi
harrop in the US say 17,000 rpm about 2.5 to 1
is about as fast as you want to go on the blower speed ? would you get any boost at all at that rpm from a 2.3 liter blower on a 454 ?? thanks for any info

no takers on this ??

man its only been half a day, i know im new here but im not new to forums give it a few days, most here have daily jobs, families n such, there's a shitton of knowledge here and it may take a little time to get a response.

The 2300 will pump enough air to see 10psi on a 454 if it has a crappy exhaust and isn't built right. It's more at home on a much smaller motor. You need to come up with a hp goal more than a boost goal. A TVS 2300 will make plus or minus 700 rwhp effeciently. If you're looking for a whole lot more power, you might be better served to find a bigger blower. Yes, it can make the bigger hp numbers. There are probably better ways to make those numbers though.

cheers no worries im just used TO our FORUM if you dont get an answer straight away in gets buried
and no one see it LOL

So this blower will work well on a stock cube LS1 f-body?

Don't have a clue if there's a kit avialable that will bolt things together easily. Do know that 5.7l's are easily fed by the 2300. It can pump enough air to make some really serious power and breaks lots of sheeeeet.

red 454

it will over feed a stock bottom end ls3 to desigened to suite 376/to 427 ci with forged bits
mine is under driven making 10psi with a stock bottom end ls3 with cam headers and full 3" duel system

It will not work on a 454.

red 454

well that is a dame shame

ayousef

is this similar to the tvs2300 because if so, someone put in a 434ci motor and couldnt get more than 6psi of boost through that supercharger. but then again, people like MTI racing made big power, but not only that, they made HUGE torque with a TVS2300 on a 500ci motor.

red 454

yes it is similar it has the same roters
any info on the 500 ci motor what blower speed ?

LOL..yeah i guess with all the low end TQ there's bound to be some broken
parts...Bye Bye stock 10 bolt..haha

I have used a HTV2300 on a built 454 with pretty good success.
I ran the Harrop 10PK pulley kit with the 3.071:1 ratio pulley set.
I also installed one of my "Dual-80" throttle bodies.
Peak psi was 14.5, & IAT's got to ~80C on the engine dyno & it pulled a little under 1000hp on pump fuel. With more tune time we would have cracked 1000hp - we only ran conserviative timing.

Those twin throttle body setups are a great looking piece of engineering

What sort of torque increase did you see from them?

red 454

very nice bit of gear
when you say built 454 can you elaborate on that
lsx block ? pistons ?comp ? cam size ect
trying to get one built to take the 2300 but no takers yet
thanks

Thanks ...
The increase in torque was not as great as I would have liked - typically 35-45 ftlb depending on application.

From memory ...
- LSX & ported/chambered LS3 heads
- Custom Mahle pistons (I think)
- ~9.5:1 CR
- 235/248, 115LSA

I did not have much to do with the engine build.
The HTV2300 was overdriven LOTS - 10PK at ~3:1 drive ratio.
