300whp Jamaica style

In an ideal world, no one would throw around or ask for 'figures'. These mean very little in the real world.

Just post up a dyno result when you have the end product. Let people digest, approve or question it how they wish.

Here's a video of a guy making 701WHP on an 11.5:1 compression 2 litre motor @ 25+psi with a stock head gasket, stock intake etc

** EDITED BY ADMIN **

thats a street racing vidoes lad we dont do that on the site

i thought the big hp cars in jamaica are running methanol or something so they can get these sort of figures.

i'm pretty certain they dont use normal 97 ron fuel out of the pumps

Rule is that I'm pretty sure any power can be acheived if required, but for what period of time and how long remains unknown, depends if you see reliability as a factor. Take a look at this email...


"Hi Nathan,

I came across your site purely by accident this morning.

I was one of the small team that launched Daihatsu in the UK in 1977 and I, and others, tested the first Gtti that was ever sent over to the UK from the factory for evaluation (in a curious pastel green colour). It required a lot of change (mainly to do with suspension) which the factory accepted without reservation.

We put a Gtti into the RAC rally one year, I think prepared by Hugh Chamberlain, and, as a side result, one red road car was prepared; it produced about 145bhp and I used it on occasion - it was a real Q car in those days.

What is not generally known is that one of the Formula 1 teams of that era (now defunct) bought three engines from us for development at a time when no decision had been made regarding the size etc of future F1 engines. I believe they were all destroyed in the process but we were told that, briefly, over 900 bhp was produced. I should emphasise that this was received information and we saw no physical proof.

Daihatsus generally were very reliable and the Charade, in all its forms, was a great favourite of mine. I ended up as sales director before moving over, within our group, to launch and then run Chrysler Jeep.

Kind regards,

Richard

this as been a very gud read and im pretty new to the gt seen and learning alot about tuning the little beast, i lik how people out there r using there imagination i went to a meet n under every ones bonnet was lik luking at the same engine cos every ones done the same n was makin me think about getting sumthing different to tune, but now this has made me start to think so cheers guys keep up the gud work

Thanks for the kind words guys. And no I'm not going to stop posting this build up because its very important to me. The people involved with with project are not part of the local tuning establishment. Let me further answer some questions.

1: We don't use 97, because we don't have 97. Jamaican gas is 87 and 90 octane with a RON number of 93. For reference JDM fuel is 102RON. I'm sure we can reach the power goals on our 90 depending on how its tuned. As for methanol/water injection I'm with Corky Bell on this one, I'm not a fan. I've seen it work, but its not too popular down here. Kinda expensive.

2: I have no question the figures can be achieved. The owner is actually building a circuit car. That's the engine he got with the car and that's what we have to tune with. I think 200whp is more than enough for our local scene as my friend's rally car using the FIA group N restrictor makes 210whp on his 4E td04L set up. He won our national drivers championship so the car is fast enough at power level. I expect this car to run on average 250whp with the option for 300whp. So what we're going to do is tune for the 300whp and then turn the boost down.

3: Sometimes in my trying to make things simple it comes across with pieces of information that advanced people, like GTti will of course recognize. I agree that boost is an important element, but many don't understand that its the CFM of the turbocharger that makes the power. Building your car for a specific boost level really is not a good starting point. What you need to do is find a turbocharger that has the CFM to meet your power needs, and then try and find a compressor map because trying to run a certain amount of boost on X turbocharger may not produce the power levels you want because you're out of the optimum operational range of that unit.

4: I have never regretted being part of GT Turbo, because you guys are the most active English-speaking online EP community in the world. The large majority of my experience here has been positive, and many of you have assisted me as well. So I really understand the skeptics, its something I've faced in my own country in relation to other projects I've worked on. As I was told I'm just going to have to do it so they can see.

5: Hi CR turbo motors are also rather common over here like the USA. There are tons of Hondas running stock CR with low boost setups. They only go POP if you try and go beyond the bonds of what it can handle.

Fair point your build thread and advice I must admit and wil say is 110%fella.

You do take time and effort to put this up, will be eagerly awaiting your final results too.

i'm going to be a nay sayer here but.......


without using some form of special racing fuel like ethanol, it will just blow.

if this wasnt the case then why isnt everyone doing it?

rory, i respect you for all you have done for the site, your very knowledgeable.

also i distinctly remember a thread on the old forum where someone from another country was saying he got 300whp and it turned out out he was running some form of fuel where you can almost run whatever knock you like and turn the boost up (cfm up) because it cooled the pistons down so much.

so are you definately sure you are running it on road going fuel?

also a member on here tried running a td04 at 1.4 bar on stock internals, and it only lasted a couple of weeks before going pop, this was done on a stock 4efte

I love threads like this that go into detail and think some of the comments in this thread are a little hostile 2 say the least. I know everyone on here loves to see build progress and thats what we should incourage; not make little comments allover his build thread! I have doubts about the stock internals but lets just wait and see what progress is made and how obstacles are tackled. Dont doubt the man until hes enforced the plan ;).
Good luck Rory, keep us updated :drive:

glanza wasnt it? and he bent a rod not pistons didnt he? 4efte rods are different from the 5e ones arent they?

rods arent any weaker, i'm not sure what happened, all i know was his engine only lasted a couple of weeks, (from memory i think the rod went through the block)

cal (i know no one likes him) tried the same thing and the same happened to his engine.

either that or us british and maltese have far to much money to burn.

there must be some secrets that the jamaicans know that we dont for this way to possibly work.

He just stated that the fuel was 93 RON, that's only slightly below standard british supermarket fuel at 95/97 RON... I imagine the fuel is of a lesser quality but with more additives to increase the resistance against detonation.

Using a richer AFR will help prevent higher cylinder head temperatures, less risk of detonation. Retarding ignition timing will ease the load on the engine. Not ideal for performance but it's up to the owner I guess.

yeah i know, i just feel he is hiding something :p

i dont mean to be pesimistic, i'm just very curious

Its just crazy how everyone in the world can get these great figures whilst us Brits cant..... :(.

We need an international meeting which is highly unlikely. Get GT's/Glanza's from all corners of the earth and all dyno'd on the same dyno in the same day.

This will never happen so there will always be doubt in peoples minds i feel.

it was the rod that faild and went into the block.

so one minute gt rods are better then glanza rods.. and now they arent any weaker? i know its not gt rods hes using.. but 5e ones and they are not as thin as glanza ones.

Disagree, we don't need that. People just need to understand that it is merely a tuning tool and a reference point for the owner.
