Courtenay Harrup Supercharger A Stage Too Far!

[A11VXL]

We've been playing with a new Harrup HTV Supercharger. This unit is a direct replacement for the LSJ M62 with an output of 1.3L VS the M62's 1.0L litre.
The engine is a 2.2 with Steel Rods, Deleted Balancer Shafts, Modified Head and Cams, 470cc injectors, complete with an awesome 3" 2bular system the Manifold is a 4 into 1 design with 2" primaries- thanks Jim.



359.93 BHP & 287.35 LBS FT. You can also see that we have not hit peak power, just smacked the limiter set @ 7000rpm!! Yes we were tempted to rev it further but we have maxed the fuel pump, so thought better off it .

Now weve got to turn it all down as our brief for the build was 300bhp !! and we are a little over the spec for the pistons!!! Jon

Fecking Hell! When is Johnny booked in then??

[Daniel]

thats wicked any pics of car ??? take it i need a hell of alot of money to have a set up like that lol ???

[Sjdickso]

Oh my word!! Dont let Johnny see this lol.

The supercharger alone is about £2,500+ now. £1.5k exhaust, it's not especially cheap However, compare it to the cost of getting 300bhp out of an Elise with a supercharged Honda and it's a bargain...

££££Tell me about it, I am certain it will be worth it though for the grin factor at least, can't wait to drive it

:O what are the pistons rated to?

/me gets saving

310 wheels

looks like you've got something that's going to be faster than a F430 or Gallardo!

Yea but only up to 150

god that some power to put down! will be eating tyres for breakfast, lunch and dinner!!!!

Great another thing to tell the wife where did my tread go

[sdbutler10]

wow thats amazing. that would be so scarey going up the road sideways all the way lol

[alanoo]

Good job, as I said on the .org a bit too much for an engine with that specs, but definitely promising for any other TVS build in the future

[rik1083]

what would it take to get the engine strong enough for more? are the parts even avialable?
Does it have the standard size pulley?

[vocky]

great job guys


ideally Nick needs some wiseco pistons, then 400 bhp is possible

on a standard z22se engine you would need; eagle steel rods, wiseco pistons, balancer delete, ported head with uprated valves (Nick has saab turbo valves), comp sc cams and a 3" exhaust system

[JohnnyN]

Doo be doo be doo????




Awesome power there Nick. Well done Jon on another fantastic job.

I'm leaving this thread now before I have the urge to sell my wife and children!!

what pistons he have now?
sounds do-able maybe.. I'd have to find a second engine first i think and build it up

[vocky]

standard !

I really hope for you the pistons will survive, but at these power it is more a chance factor than anything else.

LSJ guys are killing their stock pistons around 280-300 whp, and they are already much stronger than L61/Z22SE ones (which proved to be fine at ~250 crank on all hitec/Courtenay conversions, so around 220 whp)

+ uprated fuel pump system (with swirl pot), big injectors, ARP head bolts (400 bhp starts to be a lot for OE ones, crank ones should be fine), and ARP flywheel bolts too
(and maybe a ported inlet manifold to keep the TVS in a good pressure ratio area if the head flows)

I'll personally prefer Diamond racing or Je pistons for such a high power level too

Yea I know that's why it's on my do asap list got to drop the engine again

[rik1083]

don't the standard ones have the wrong compression? or are you still using the head spacer?

[nickb777]

Spacer on mine to reduce comp ratio

A must have for those who do not have a full access to the ECU maps of course
